Crash bug blights Cisco IP phones

Firmware flaw

Build a business case: developing custom apps

Cisco has advised users to update the firmware on some of its IP phones following the discovery of two security flaws.

A brace of Session Initiation Protocol (SIP) vulnerabilities in Cisco 7940/7960 IP Phones create the potential for hackers to crash - but not to run exploit code - on vulnerable handsets.

SIP is a signalling protocol for VoIP. The protocol can be used to create two-party, multiparty, or multicast sessions.

Cisco IP Phone 7940/7960 SIP firmware versions prior to 8.7(0) are vulnerable to the denial of service attacks, Cisco warns. Users are advised to update their firmware to version 8.7(0), as explained in its advisory here.

More detail on the vulnerabilities can be found in posts (here and here) to full disclosure mailing lists by the independent security researchers (Radu State, Humberto J Abdelnur, and Olivier Festor) who discovered the bugs. ®
