php: unserialize() SPL ArrayObject / SPLObjectStorage type confusion flaw
Published Jul 9, 2014
7.5
HIGHCVSS 2.0
EPSS 30.13%
Description
The SPL component in PHP before 5.4.30 and 5.5.x before 5.5.14 incorrectly anticipates that certain data structures will have the array data type after unserialization, which allows remote attackers to execute arbitrary code via a crafted string that triggers use of a Hashtable destructor, related to "type confusion" issues in (1) ArrayObject and (2) SPLObjectStorage.
