TITLE:
PHPIDS "unserialize()" PHP Code Execution

SECUNIA ADVISORY ID:
SA37642

VERIFY ADVISORY:
http://secunia.com/advisories/37642/

DESCRIPTION:
Stefan Esser has reported a vulnerability in PHPIDS, which can be
exploited by malicious people to compromise a vulnerable system.

The vulnerability is caused due to the "runCentrifuge()" function
using unserialize() with user controlled input. This can be exploited
to e.g. execute arbitrary PHP code via the "__wakeup()" or
"__destruct()" methods when a specially crafted string is being
unserialized.

The vulnerability is reported in versions prior to 0.6.3.1.

SOLUTION:
Update to version 0.6.3.1.

PROVIDED AND/OR DISCOVERED BY:
Stefan Esser, SektionEins GmbH.
