| fast-uri is a dependency-free RFC 3986 URI parser and serializer for Node.js. In versions before 2.4.8, from 3.0.0 through 3.1.8, and from 4.0.0 through 4.2.2, fast-uri percent-decodes the scheme component with the legacy global unescape() function before validating it, so an input whose decoded scheme is a dangerous token is emitted as a live scheme even though RFC 3986 does not allow percent-encoding in a scheme and no other parser accepts it. An application that screens dangerous schemes on the raw input and then stores or renders the normalized or resolved result can turn an inert string into an executable javascript, data, or vbscript URL, producing a stored or reflected cross-site scripting vector, and the equal() comparison treats an encoded and a plain scheme as the same, which can bypass equality-based allowlists. The issue is fixed in fast-uri 2.4.8, 3.1.9, and 4.2.3, and users should upgrade to one of these versions or later. As a workaround, reject input whose scheme part contains a percent sign, or check the parsed scheme against an allowlist after normalization and use that same parsed result rather than the raw string. |
| fast-uri is a dependency-free RFC 3986 URI parser and serializer for Node.js. In versions from 2.4.2 through 2.4.7, from 3.1.3 through 3.1.8, and from 4.0.1 through 4.2.2, for HTTP-family schemes the canonicalizeHost() function passes the parsed host to the WHATWG URL parser and adopts its hostname without checking that the parser consumed the entire input as a host, so the authority can be silently rewritten: data before an at-sign is dropped and tab, carriage-return, and line-feed characters are stripped, with no error reported. An application that enforces host-based policy such as denylists, loopback filtering, redirect validation, or outbound proxy routing on one representation can then see the canonical host diverge from what it checked, allowing traffic to be steered to an unintended destination. The issue is fixed in fast-uri 2.4.8, 3.1.9, and 4.2.3, and users should upgrade to one of these versions or later. As a workaround, reject an authority that contains more than one at-sign or any tab, carriage-return, or line-feed before calling fast-uri, or treat any non-empty parse error as fatal and compare hosts only from the same parse result. |
| json-smart through 2.6.0 contains an input validation bypass vulnerability that allows attackers to evade strict-mode trailing-data checks by inserting a literal 0x1A character. Attackers can append 0x1A and malformed content to pass JSONValue.parseStrict or isValidJsonStrict validation, creating parser differentials with downstream parsers like Jackson or Gson. |
| In MariaDB server version through 11.8.5, when server audit plugin is enabled with server_audit_events variable configured with QUERY_DCL, QUERY_DDL, or QUERY_DML filtering, if an authenticated database user invokes a SQL statement prefixed with double-hyphen (—) or hash (#) style comments, the statement is not logged. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: rtw89: pci: validate release report content before using for RTL8922DE
The commit 957eda596c76
("wifi: rtw89: pci: validate sequence number of TX release report")
does validation on existing chips, which somehow a release report of SKB
becomes malformed. As no clear cause found, add rules ahead for RTL8922DE
to avoid crash if it happens. |
| RabbitMQ is a messaging and streaming broker. From 3.13.0 until 3.13.19, 4.0.24, 4.1.15, 4.2.10, and 4.3.5, the MQTT 5 parser in deps/rabbitmq_mqtt/src/rabbit_mqtt_packet.erl accepts Request-Problem-Information on PUBLISH packets even though the property is valid only for CONNECT. An authenticated publisher with topic write permission can cause the broker to store and route that inapplicable property to a separately authenticated matching subscriber. When the subscriber path serializes the outbound PUBLISH, serialise_prop/2 has no matching clause, and the uncontained function_clause exception closes the victim MQTT or Web MQTT connection. The publisher connection and broker remain available, and queued replay, retained-message persistence, and broker-wide denial of service were not established. This issue is fixed in versions 3.13.19, 4.0.24, 4.1.15, 4.2.10, and 4.3.5. |
| An Improper Validation of Syntactic Correctness of Input vulnerability in the VPN daemon of Juniper Networks Junos OS on SRX Series allows an authenticated, network-based attacker to take complete control of the device.
If an SRX device configured for AutoDiscovery VPN (ADVPN) receives a message from a peer that contains one or more specifically malformed attributes, this will cause a buffer overflow, which can allow remote code execution and therefore allow an attacker to take complete control of the device. To be able to carry out this attack an attacker must either have acquired the shared secret to impersonate a peer or have compromised an existing one, so this attack is considerably difficult.
This issue affects Junos OS on SRX Series:
* All versions before 23.2R2-S7.7;
* from 23.4 before 23.4R2-S7;
* from 24.2 before 24.2R2-S4;
* from 24.4 before 24.4R2-S3;
* from 25.2 before 25.2R2;
* from 25.4 before 25.4R1-S3. |
| Improper Validation of Syntactic Correctness of Input vulnerability in mtrudel bandit allows an unauthenticated remote attacker to set conn.host and conn.port to values outside the RFC 3986 host grammar via the authority of an HTTP/1 absolute-form or authority-form request target. Bandit validates the Host header and answers 400 when it is malformed, but when the request target carries its own authority that authority takes precedence, as RFC 9112 requires, and Bandit.Pipeline.determine_host_and_port!/4 in lib/bandit/pipeline.ex passes it to the application unchecked. A request line such as GET http://good.example@evil.example/x HTTP/1.1 with a valid Host header yields a conn.host of good.example@evil.example, and the same path admits NUL, DEL and non-ASCII bytes, invalid IP literals and ports outside 1..65535. The HTTP/1.0 clause needs no Host header at all, and CONNECT places the unparsed port string in conn.port.
Applications that build absolute URLs from conn.host, such as through Plug.Conn.request_url/1 or Phoenix URL helpers, emit links whose authority the attacker chose. Message framing is unaffected, and no CR or LF can reach conn.host.
This issue affects bandit: from 0.6.0 before 1.13.0. |
| In the Linux kernel, the following vulnerability has been resolved:
ocfs2: reject dinodes with non-canonical i_mode type
Patch series "ocfs2: harden inode validators against forged metadata", v2.
This series adds three structural checks to OCFS2 dinode validation so
malformed on-disk fields are rejected before ocfs2_populate_inode() copies
them into the in-core inode.
The checks cover:
- i_mode values whose type bits do not name a canonical POSIX file
type;
- non-device dinodes whose id1.dev1.i_rdev field is non-zero; and
- non-inline dinodes that claim non-zero i_size while i_clusters is
zero, covering directories unconditionally and regular files on
non-sparse volumes.
The normal read path reports these through ocfs2_error(), matching the
existing suballoc-slot, inline-data, chain-list, and refcount checks. The
online filecheck path uses the same structural predicates but keeps its
own reporting contract, returning OCFS2_FILECHECK_ERR_INVALIDINO instead
of calling ocfs2_error().
This patch (of 3):
ocfs2_validate_inode_block() currently accepts any non-zero i_mode value.
ocfs2_populate_inode() then copies that mode verbatim into inode->i_mode
and dispatches on i_mode & S_IFMT to the file/dir/symlink/special_file
iops; an unrecognised type falls through to ocfs2_special_file_iops and
init_special_inode().
Reject dinodes whose type bits do not name one of the seven canonical
POSIX file types. Use fs_umode_to_ftype(), the same generic file-type
conversion helper OCFS2 already uses for directory entries, so the
accepted inode type set matches the kernel file-type vocabulary instead of
open-coding a local switch.
Apply the same structural check to the online filecheck read path.
filecheck keeps its own error namespace, so it reports malformed i_mode
through the filecheck logger and OCFS2_FILECHECK_ERR_INVALIDINO instead of
calling ocfs2_error(), but it must not allow a malformed dinode to proceed
into ocfs2_populate_inode(). |
| When curl is used to retrieve and parse cookies from a HTTP(S) server, itaccepts cookies using control codes that when later are sent back to a HTTPserver might make the server return 400 responses. Effectively allowing a"sister site" to deny service to all siblings. |
| An issue in FinalWire AIRDA Extreme, AIDA64 Engineer, AIDA64 Business, AIDA64 Network Audit through 7.00.6742 allows a local attacker to escalate privileges via the DeviceIoControl call associated with MmMapIoSpace, IoAllocateMdl, MmBuildMdlForNonPagedPool, or MmMapLockedPages components. |
| IEEE 802.11 protocol dissector crash in 4.6.0 to 4.6.8 and 4.4.0 to 4.4.18 allows denial of service |
| PyJWT is a Python implementation of JSON Web Token standards. Prior to 2.14.0, PyJWT signature segment is affected because signature segment decoding accepts characters outside the canonical Base64URL representation. This occurs when non-Base64URL characters are appended to a valid compact JWS signature segment. As a result, base64url_decode produces the same signature bytes for different serialized segments. Consequently, raw-token revocation checks can fail to recognize an equivalent modified token. This issue is fixed in version 2.14.0. |
| A flaw was found in Keycloak. A remote, unauthenticated attacker can send a specially crafted XML input to the Security Assertion Markup Language (SAML) endpoint. This malicious input can cause high CPU usage and worker thread starvation, leading to a Denial of Service (DoS) where the server becomes unavailable. |
| ImageMagick before 7.1.2-32 and 6.9.13-57 contains a policy bypass vulnerability in LoadPolicyCache that silently skips security policy rules when policy.xml uses an alternate DOCTYPE. A valid DOCTYPE not ending in ']>' makes the parser consume the rest of the file, so no policy rules are applied and restricted operations become allowed. |
| Net::IDN::Punycode::PP versions before 2.590 for Perl decode a truncated label to a name containing a character it never encoded in decode_punycode.
The pure-Perl decoder reads one digit at a time with four-argument substr and tests the result with defined to detect the end of the input. substr on an exhausted string returns the empty string rather than undef, so decoding continues past the end. The empty string converts to a digit value below the range, reducing the accumulator, and the decoder derives one extra code point and its position from it. The result is deterministic. The XS backend rejects the same label.
Net::IDN::Punycode uses this backend wherever the XS does not build.
The two backends disagree about what such a label means, so a sender can pick a label that one installation resolves to a name and another rejects. |
| Net::IDN::Punycode versions before 2.590 for Perl hang, crash or return a wrong label via unvalidated malformed UTF-8 in encode_punycode.
Neither backend checks that its input is well-formed UTF-8, so a string with the UTF-8 flag set over malformed bytes, as the :utf8 PerlIO layer produces from any malformed input, reaches the encoder unchecked. On perl 5.32 and later the XS backend reports a malformed sequence with a length of `(STRLEN)-1`, so the scan steps back one byte instead of forward and never ends. On earlier perls the XS returns a valid label for a different name. The pure-Perl backend runs a regex over the flagged string. Depending on the bytes, it aborts with SIGBUS on perl 5.28 and later, dies with a panic, or returns a wrong label.
The documented conversion functions match the label against Unicode properties first and that match dies on such a string, so only a direct call to encode_punycode reaches the defect. The decoder is not affected.
A direct caller encoding attacker-supplied bytes hangs, crashes or gets a label for a name the input never held. |
| A vulnerability was determined in Barco ClickShare CX-20 Gen2 up to 02.26.00.0007. Affected by this issue is some unknown functionality of the file /wallpaper of the component Wallpaper Upload. This manipulation of the argument wallpaper causes improper validation of syntactic correctness of input. The attack can be initiated remotely. The exploit has been publicly disclosed and may be utilized. The vendor was contacted early about this disclosure but did not respond in any way. |
| Nodemailer is a Node.js email-sending library. In versions >= 9.1.0 and < 10.0.9, the address parser (src/addressparser) mishandles addresses whose local-part is a quoted string and that are followed by RFC 5322 comments, allowing trailing comment-separated domain atoms to be retained in the normalized address. For example, the input "user"@example.com(x)evil.com is parsed to the address value 'user@example.com evil.com', which contains additional attacker-controlled domain text separated by a literal space. This parsed value is used without further strict recipient validation when the message envelope is built (envelope.to in src/mime-node), so a malformed/ambiguous recipient address can be accepted and placed in the SMTP envelope. Whether this results in delivery to an unintended recipient on real SMTP servers has not been confirmed. The issue is a variant of the RFC 5322 comment parsing problem addressed in GHSA-cc9r-2j5m-2m83, affecting the separate quoted-local-part code path. Version 10.0.9 contains a fix. |
| A vulnerability has been found in Trusted Domain Project OpenDMARC up to 1.4.2. This affects the function opendmarc_policy_parse_dmarc in the library libopendmarc/opendmarc_policy.c. The manipulation of the argument fo/rf/ri/pct/sp/adkim/aspf/rua/ruf leads to handling of exceptional conditions. Remote exploitation of the attack is possible. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way. |
