CVE-2018-0325 describes a denial-of-service vulnerability affecting Cisco IP Phone 7800 and 8800 Series phones. This flaw stems from incomplete input validation of SIP Session Description Protocol (SDP) parameters. An unauthenticated, remote attacker can exploit this by sending a malformed SIP packet, causing active calls to drop and the phone's SIP process to restart. Rated 7.5 HIGH on CVSS, the attack requires no user interaction and has a high impact on availability. There is no known exploit code publicly available, nor is there evidence of active exploitation or significant community discussion.
