| Authentication bypass by spoofing vulnerability in Apache Syncope.
When the configured JWKS settings for internal JWT authentication are disclosed (at least protocol and key), an attacker can spoof another user's privileges after completing a successful authentication and obtaining a valid JWT.
This issue affects Apache Syncope: from 3.0.0-M0 through 3.0.16, from 4.0.0-M0 through 4.0.7, from 4.1.0-M0 through 4.1.2.
Users are recommended to upgrade to version 4.0.8 / 4.1.3, which fix this issue. |
| Description
A submitted topology carries two lists of blobstore keys, `dependency_jars` and `dependency_artifacts`,
which the client fills in after uploading the corresponding blobs. Nimbus performed no validation of their
contents on the submission path, yet acts on them in two places.
During cleanup of a finished topology, Nimbus deletes the keys named in those lists, and the deletion is
performed as the Nimbus subject, for which the blobstore short-circuits its ACL check. A submitter who
listed a key belonging to another topology, such as its `-stormjar.jar`, could therefore cause
that blob to be deleted when their own topology was cleaned up.
Separately, on acquiring leadership a Nimbus compares the dependency keys of all active topologies against
the blobstore contents and surrenders leadership if any is missing. A single key that does not exist, on a
single active topology, therefore causes every Nimbus to acquire leadership, surrender it and requeue
indefinitely, leaving the cluster without a leader and unable to schedule, clean up or accept submissions.
Mitigation
Upgrade to 3.1.0, where a submission is refused unless every entry in both lists is a dependency blob key
and exists in the blobstore.
Note that this validates new submissions only; a topology stored by an affected version with an invalid list
is unaffected by the upgrade. An operator whose cluster is failing to retain a leader should inspect the
Nimbus log for the dependency keys reported as missing and remove or resubmit the topology naming them.
Users who cannot upgrade immediately should restrict topology submission to trusted principals.

| Description
Nimbus validated `topology.blobstore.map` against the calling subject at submission time only. The rebalance
operation accepts configuration overrides and stripped a small set of keys from them, but never re-ran that
validation, so a caller authorised to rebalance a topology could introduce a blobstore map entry naming a
blob whose ACL does not grant them access. Supervisors localise whatever key the map names, placing the
blob's contents into the topology's working directory.
The same advisory covers `listBlobs`, which performed no authorization check and passed no subject, unlike
the neighbouring `getBlobMeta` and `beginBlobDownload` operations. It therefore returned every key in the
blobstore to any caller able to reach the Nimbus Thrift port, which provides the key names that make the
above practical. On its own the disclosure is metadata only.
Mitigation
Upgrade to 3.1.0, where rebalance configuration overrides are validated exactly as submission-time
configuration is, against the rebalancing caller, and where `listBlobs` applies the configured
authorization.
Users who cannot upgrade immediately should restrict rebalance rights to trusted principals, keeping in mind
that membership of a topology's `topology.users` or `topology.groups` confers them.

| Description
`SimpleACLAuthorizer` evaluated the user-level command set by returning early when `nimbus.users` was empty,
before `nimbus.groups` was considered. An operator who restricted cluster access by group alone, leaving
`nimbus.users` unset, therefore received no restriction at all: every authenticated principal was permitted
every user-level operation, including `submitTopology`, `beginFileUpload` and `getNimbusConf`.
`docs/SECURITY.md` presents `nimbus.groups` as a supported way to lock down a cluster, so a deployment
following the documentation could believe it was restricted while it was not. The failure is silent; nothing
in the logs or the configuration indicates that the group list is being ignored.
Both lists left empty continues to mean that no restriction is configured, which is the shipped default and
is unchanged.
Mitigation
Upgrade to 3.1.0, where `nimbus.groups` is evaluated whether or not `nimbus.users` is set.
Users who cannot upgrade immediately should additionally populate `nimbus.users` with the intended
principals, since a non-empty user list causes the group list to be evaluated on affected versions.
Operators should review Nimbus access logs for operations by principals outside the intended groups.
Note that after upgrading, a cluster configured with `nimbus.groups` alone becomes restrictive for the first
time. This includes `NimbusClient`, which calls `getLeader` on every connection, so clients outside the
configured groups will begin to be refused.

| Description
A topology's `topology.blobstore.map` lets the submitter choose a local name for each blob that the
supervisor localises. That name was used to build a path under the topology's working directory without
normalisation, in both `AsyncLocalizer` and `Container.createBlobstoreLinks`, and the symlink helper
force-deletes whatever already exists at the target before creating the link.
A submitter could therefore use `../` segments to direct that delete-and-symlink operation at an arbitrary
path, as the supervisor user, on every node the topology is scheduled onto. The consequences include
recursive deletion of supervisor-owned content and planting a symlink that causes a subsequent worker
launch to execute attacker-chosen code as another tenant's operating-system user, which defeats the
isolation that `supervisor.run.worker.as.user` is intended to provide.
Mitigation
Upgrade to 3.1.0, where the resolved target must lie inside the expected root at both call sites.
Users who cannot upgrade immediately should restrict topology submission to trusted principals, and may
reject submissions whose `topology.blobstore.map` entries contain path separators or `..` segments before
they reach Nimbus.

| Incorrect Implementation of Authentication Algorithm in the password-reset and login JWT validation in Apache OFBiz 24.09 before 24.09.08 on all platforms allows an attacker who has obtained a user's password-reset token (via email interception, log exposure, or a man-in-the-middle on the mail transport) to authenticate as that user and obtain a full, unrestricted session, including administrative access if the targeted account is an administrator, by submitting the token directly to the login endpoint instead of the intended password-change flow. Users are recommended to upgrade to version 24.09.08, which fixes this issue. |
| Incorrect Privilege Assignment in the Order Manager in Apache OFBiz 24.09 before 24.09.08 on all platforms allows an authenticated user who holds only order view permissions (ORDERMGR_VIEW), without ORDERMGR_UPDATE or any role on the order, to modify approved orders, changing a ship group's shipping address and shipment method or appending items with an overridden price, via the updateShipGroupShipInfo and appendOrderItem services. Users are recommended to upgrade to version 24.09.08, which fixes this issue. |
| Uncontrolled Resource Consumption in ServiceMultiEventHandler in Apache OFBiz 24.09 before 24.09.08 on all platforms allows a remote unauthenticated attacker to pin a server request thread for an attacker-chosen number of synchronous service dispatches, up to the signed-integer maximum, by submitting a single small HTTP request whose parameter names encode a row count via the "o" suffix used by multi-form submissions, because UtilHttp.getMultiFormRowCount derives that count from the largest such suffix with no upper bound and ServiceMultiEventHandler.invoke then loops that many times calling dispatcher.runSync, with the request-map for getFinAccountTransRunningTotalAndBalances reaching this handler with no authentication or CSRF requirement on a stock deployment. Users are recommended to upgrade to version 24.09.08, which fixes this issue. |
| Authentication Bypass by Capture-replay in ExternalLoginKeysManager in Apache OFBiz 24.09 before 24.09.08 on all platforms allows a remote unauthenticated attacker who captures a live externalLoginKey value to obtain a complete, cookie-free, reusable session as the user who issued it, in every webapp that user can reach, because checkExternalLoginKey runs as a global preprocessor ahead of both the CSRF and authentication checks and accepts the key as a bearer credential that is never bound to a client, never expires, and is not invalidated after use, while the framework itself both appends live keys to every cross-webapp link it renders and, via WidgetWorker's unvalidated inter-app link target, lets an authenticated user's key be attached to an attacker-chosen absolute URL and delivered directly to the attacker's own server. Users are recommended to upgrade to version 24.09.08, which fixes this issue. |
| Improper Neutralization of Special Elements Used in a Template Engine ('Server-Side Template Injection') in MacroScreenRenderer in Apache OFBiz 24.09 before 24.09.08 on all platforms allows a remote authenticated attacker holding only the two view permissions of a control-servlet webapp (e.g. CATALOG_VIEW and OFBTOOLS_VIEW on /catalog, held by OFBiz's own shipped order-entry clerk role) to execute arbitrary operating system commands as the OFBiz service account with a single GET request, by placing an apostrophe followed by FreeMarker expression source in a screen link parameter value, because renderLink concatenates link parameter values verbatim between apostrophes into an unquoted, unescaped template-source string that is compiled and evaluated at render time, allowing the injected expression to reach the allow-listed FlexibleStringExpander.expandString call and, through a runtime-assembled Groovy interpolation, unsandboxed code execution. Users are recommended to upgrade to version 24.09.08, which fixes this issue. |
| Improper Neutralization of Special Elements Used in an Expression Language Statement ('Expression Language Injection') in EmailServices in Apache OFBiz 24.09 before 24.09.08 on all platforms allows a remote authenticated attacker holding only OFBTOOLS_VIEW and ACCOUNTING_VIEW, the two view-level permissions that open the Accounting application, to execute arbitrary operating system commands as the account running OFBiz, by submitting a ${groovy:...} expression as the bodyText or subject value to the shipped Send Per Email invoice form, because sendMailFromScreen passes those caller-supplied values through FlexibleStringExpander.expandString, which compiles and evaluates embedded Groovy on a class loader that carries none of the SecureASTCustomizer restrictions GroovyUtil.eval applies elsewhere, behind a service and request-map that declare no permission check beyond base authentication. Users are recommended to upgrade to version 24.09.08, which fixes this issue. |
| Missing Authorization in XmlDsDump in Apache OFBiz 24.09 before 24.09.08 on all platforms allows a remote authenticated attacker holding only the webtools base permissions (OFBTOOLS_VIEW, WEBTOOLS_VIEW) — explicitly not the ENTITY_MAINT permission the export feature declares and visibly refuses to render for — to export the contents of any database entity, including UserLogin with its currentPassword hashes, to any filesystem path the OFBiz process can write, including a web-served docroot, and to create arbitrary directories or truncate arbitrary existing files at those paths, because the XmlDsDump screen action writes the requested entity data via new FileOutputStream on unvalidated outpath and filename request parameters before the screen's ENTITY_MAINT permission check runs, unlike the equivalent Java service entityExportAll, which enforces both a permission check and a file-path allow-list. Users are recommended to upgrade to version 24.09.08, which fixes this issue. |
| Improper Control of Generation of Code ('Code Injection') in ModelFormField in the Apache OFBiz cms plugin before 24.09.08 on all platforms allows a remote authenticated attacker holding only CMS content-editor access to execute arbitrary operating system commands as the OFBiz process user via a single HTTP POST request, by submitting a crafted caContentIdTo parameter to EditAddContent, because the CMS screen copies that parameter into a top-level context variable that is interpolated into a form field's use-when attribute and the resulting string is passed unvalidated to GroovyUtil.eval(), whose compile-time SecureASTCustomizer sandbox does not restrict runtime reflection, allowing a payload that closes the expanded string literal and invokes java.lang.Runtime via reflection. Users are recommended to upgrade to version 24.09.08, which fixes this issue. |
| Improper Control of Generation of Code ('Code Injection') in Apache OFBiz 24.09 before 24.09.08 on all platforms allows a remote unauthenticated attacker to execute arbitrary code on the server by staging crafted widget XML in a multipart upload and overriding the mainDecoratorLocation used by a manager login route through an anonymous JSON request, causing OFBiz to load the staged XML through its live screen descriptor mechanism and evaluate an unsandboxed Groovy expression while rendering the authentication-failure page. Further validation established the following:
-- The exploit does not require a malformed or incomplete multipart body: a well-formed multipart request that is kept in flight and then allowed to complete normally is sufficient.
-- The screen loader reads the widget XML from a live process file descriptor while the upload is streaming, rather than from any file the attacker persists to disk.
-- The same underlying issue is also reachable through the public, explicitly unauthenticated /sfa/control/editPortalPageColumnWidth route, returning command output directly in an HTTP 200 response — it is not limited to the login-failure rendering path used in the original report.
Users are recommended to upgrade to version 24.09.08, which fixes this issue. |
| Incorrect Authorization in the updateLayout simple-method in applications/content/minilang/layout/LayoutEvents.xml in Apache OFBiz 24.09 before 24.09.08 on all platforms allows a remote authenticated attacker holding only OFBTOOLS_VIEW and CONTENTMGR_VIEW to execute arbitrary commands as the OFBiz process user, by using updateLayout's authorization check — which validates only the fixed CONTENT_CREATE operation rather than an update permission on the actual Content record and an independently selected DataResource — to relink an existing RESPONSE-purpose Content record and convert an arbitrary, independently selected DataResource into an OFBIZ_FILE/FTL resource pointed at the OFBiz access log, poisoned via a crafted User-Agent header and evaluated through the normal authenticated showContent route. Users are recommended to upgrade to version 24.09.08, which fixes this issue. |
| Improper Neutralization of Special Elements Used in a Template Engine ('Server-Side Template Injection') in Apache OFBiz 24.09 before 24.09.08 on all platforms allows a remote authenticated attacker holding only a stock non-administrative account to execute arbitrary operating system commands as the OFBiz process user, by using the updateLayoutImage event, which writes DataResource fields with no permission check, to retype an attacker-created DataResource as an FTL template evaluating its own primary key, then using the resulting FreeMarker evaluation to plant an OFBiz Form Widget whose use-when attribute runs unsandboxed Groovy. Users are recommended to upgrade to version 24.09.08, which fixes this issue. |
| Incorrect default value in the REST API framework's .rest.xml definition parser (ModelApiReader) in Apache OFBiz through 24.09.07 on all platforms allows a remote, unauthenticated attacker to invoke a REST API operation without providing valid credentials via a .rest.xml resource or operation definition that omits the auth attribute, which ModelApiReader incorrectly resolves to false instead of the true default declared by rest-api.xsd.
Users are recommended to upgrade to version 24.09.08, which fixes this issue. |
| A buffer overflow vulnerability in the Brotli decoder (c/dec/decode.c) in Google Brotli versions 1.0.3 through 1.2.0 on all platforms allows a remote unauthenticated attacker to corrupt adjacent decoder state memory, disclose sensitive memory contents, cause a denial of service, or potentially execute arbitrary code using a crafted Brotli-compressed stream.
Users need to update any Brotli libraries or binaries between 1.0.3 through 1.2.0 to the latest available version: 1.0.10 or 1.1.1 or 1.2.1. |
| ** UNSUPPORTED WHEN ASSIGNED ** Deserialization of an inbound SOAP fault in Apache Axis 1.x allows unauthenticated remote class instantiation. When a SOAP <Fault> carries a <detail><exceptionName> element, Axis loads the named class and, if a String <data> element is also present, instantiates it through its String constructor before checking that it is an AxisFault. Loading alone runs the class's static initializer. With a suitable class on the application's classpath this leads to remote code execution. The fault is parsed while the engine resolves the target service, before any per-service handler chain runs, so authentication handlers configured on a service do not protect against it. This affects all Apache Axis 1.x versions through 1.4.
As Axis 1 has been EOL we recommend you migrate to a different SOAP engine, such as Apache Axis 2/Java. Alternatively you could use a build of Axis with the patch from https://github.com/apache/axis-axis1-java/commit/41f3b4e8d04e310ca81f86b92630ab2c11d608bd applied. The Apache Axis project does not expect to create an Axis 1.x release fixing this problem. |
| Allocation of Resources Without Limits or Throttling in Apache James Mime4J library prior version 0.8.15 allows Denial of Service upon parsing Mime messages.
Users are recommended to upgrade to version 0.8.15 which fixes the issue by enforcing new limits and providing better defaults. |
