Remote code execution via unchecked deserialized object
Published Mar 22, 2024 · Updated Aug 20, 2024
Deserialization in FriendsOfSymfony1 Symfony1 1.1.0 through 1.5.18 allows remote attackers to execute code through crafted PHP objects. sfNamespacedParameterHolder accepts non-array deserialized data, indexes it, and invokes an attacker-controlled callback through sfOutputEscaperArrayDecorator. Exploitation requires application code to pass untrusted serialized input to PHP unserialize; the framework alone exposes no direct attack path.
