Details

HTTPServerILServlet.java in JMS over HTTP Invocation Layer of the JbossMQ implementation, which is enabled by default in Red Hat Jboss Application Server <= Jboss 4.X does not restrict the classes for which it performs deserialization, which allows remote attackers to execute arbitrary code via crafted serialized data.

Summary
Grav has Insecure Deserialization in File Cache
Details

Insecure Deserialization in File Cache

  • Severity: High
  • CWE: CWE-502
  • Location: system/src/Grav/Framework/Cache/Adapter/FileCache.php
  • Sink: unserialize($value, ['allowed_classes' => true])

Affected version(s)

  • Affected: >= 1.7.44 and <= 1.7.49.5 (verified in current codebase and changelog-covered releases).
  • Fixed: No upstream fix identified in the reviewed branch at the time of analysis.
  • Notes: Earlier 1.7.x releases may also be affected, but were not fully back-traced in this review.

Notes

allowed_classes => true allows object instantiation and does not constrain classes.

PoC (Primitive Demonstration)

Preconditions

  • Local PHP runtime.
  • Goal is to validate the deserialization primitive used in cache retrieval.

Steps

php -r '
class CacheWakeup { public function __wakeup(){ file_put_contents("/tmp/grav_filecache_poc.txt", "wakeup"); } }

$payload = serialize(new CacheWakeup());
unserialize($payload, ["allowed_classes" => true]);

echo file_exists("/tmp/grav_filecache_poc.txt") ? "FILECACHE_UNSERIALIZE_TRIGGERED\n" : "FILECACHE_UNSERIALIZE_NOT_TRIGGERED\n";
'

Expected Result

  • Output contains: FILECACHE_UNSERIALIZE_TRIGGERED.

Interpretation

This reproduces the same unsafe primitive used by FileCache::doGet(): unserialize($value, ['allowed_classes' => true]). If cache files are attacker-tampered, object magic methods may execute.

Exploit Preconditions

  • Cache file poisoning/tampering capability.

Recommendation

  • Avoid object deserialization in cache payloads.
  • Use non-object formats and integrity protection for cache files.

Maintainer note — fix applied (2026-04-24)

Fixed in Grav core on the 2.0 branch: commit c66dfeb5f — will ship in 2.0.0-beta.2.

What changed: Framework\Cache\Adapter\FileCache now HMAC-signs every cache payload with Security::getNonceKey() on write, and verifies the HMAC on read. Tampered, forged, or pre-upgrade files are treated as cache misses and unlinked instead of being unserialized. The on-disk format is now versioned:

v2
<expires>
<key>
<hmac-hex>
<serialized>

Existing caches rebuild transparently on first read. Note that Framework\Cache\Adapter\FileCache isn't wired into Grav's main cache path — Symfony's FilesystemAdapter is — but the class is reachable by plugin and downstream consumers, so the hardening applies defensively.

Files: - system/src/Grav/Framework/Cache/Adapter/FileCache.php. - tests/unit/Grav/Common/Security/FileCacheSecurityTest.php — round-trip, tampered-payload rejection, wrong-key forgery rejection, pre-v2 file rebuild, key-field mismatch.

Summary
Deserialization of untrusted data in FasterXML jackson-databind
Details

A Polymorphic Typing issue was discovered in FasterXML jackson-databind 2.x before 2.9.9.2, 2.8.11.4, 2.7.9.6, and 2.6.7.3. This occurs when Default Typing is enabled (either globally or for a specific property) for an externally exposed JSON endpoint and the service has the logback jar in the classpath.

Summary
SGLanG: Multimodal scheduler deserializes untrusted pickle data on 0.0.0.0 ROUTER socket
Details

SGLang's multimodal generation runtime scheduler's ROUTER socket binds to 0.0.0.0 by default and contains a sink that calls pickle.loads() on incoming messages, enabling RCE when exposed to the internet.

Details

** DISPUTED ** Manuskript through 0.12.0 allows remote attackers to execute arbitrary code via a crafted settings.pickle file in a project file, because there is insecure deserialization via the pickle.load() function in settings.py. NOTE: the vendor's position is that the product is not intended for opening an untrusted project file.

Mitigation
Architecture and Design Implementation

If available, use the signing/sealing features of the programming language to assure that deserialized data has not been tainted. For example, a hash-based message authentication code (HMAC) could be used to ensure that data has not been modified.

Mitigation
Implementation

When deserializing data, populate a new object rather than just deserializing. The result is that the data flows through safe input validation and that the functions are safe.

Mitigation
Implementation

Explicitly define a final object() to prevent deserialization.

Mitigation
Architecture and Design Implementation
  • Make fields transient to protect them from deserialization.
  • An attempt to serialize and then deserialize a class containing transient fields will result in NULLs where the transient data should be. This is an excellent way to prevent time, environment-based, or sensitive variables from being carried over and used improperly.
Mitigation
Implementation

Avoid having unnecessary types or gadgets (a sequence of instances and method invocations that can self-execute during the deserialization process, often found in libraries) available that can be leveraged for malicious ends. This limits the potential for unintended or unauthorized types and gadgets to be leveraged by the attacker. Add only acceptable classes to an allowlist. Note: new gadgets are constantly being discovered, so this alone is not a sufficient mitigation.

Mitigation
Architecture and Design Implementation

Employ cryptography of the data or code for protection. However, it's important to note that it would still be client-side security. This is risky because if the client is compromised then the security implemented on the client (the cryptography) can be bypassed.

Mitigation MIT-29
Operation

Strategy: Firewall

Use an application firewall that can detect attacks against this weakness. It can be beneficial in cases in which the code cannot be fixed (because it is controlled by a third party), as an emergency prevention measure while more comprehensive software assurance measures are applied, or to provide defense in depth [REF-1481].

CAPEC-586: Object Injection

An adversary attempts to exploit an application by injecting additional, malicious content during its processing of serialized objects. Developers leverage serialization in order to convert data or state into a static, binary format for saving to disk or transferring over a network. These objects are then deserialized when needed to recover the data/state. By injecting a malformed object into a vulnerable application, an adversary can potentially compromise the application by manipulating the deserialization process. This can result in a number of unwanted outcomes, including remote code execution.
