PHPIDS unserialize() Vulnerability: Reusing Framework Object Chains

Stefan Esser · SektionEins · 8 December 2009

Explains how PHPIDS turns inspection of attacker input into unsafe PHP object deserialization. In Zend Framework applications, a crafted object graph can chain a logging destructor through mail shutdown and layout rendering to a preg_replace filter, enabling PHP code execution. The advisory traces the existing classes used by the chain and identifies PHPIDS 0.6.3.1 as the fix.
