The SIP channel driver in Asterisk Open Source 1.8.x before 1.8.20.2, 10.x before 10.12.2, and 11.x before 11.2.2; Certified Asterisk 1.8.15 before 1.8.15-cert2; Asterisk Business Edition (BE) C.3.x before C.3.8.1; and Asterisk Digiumphones 10.x-digiumphones before 10.12.2-digiumphones exhibits different behavior for invalid INVITE, SUBSCRIBE, and REGISTER transactions depending on whether the user account exists, which allows remote attackers to enumerate account names by (1) reading HTTP status codes, (2) reading additional text in a 403 (aka Forbidden) response, or (3) observing whether certain retransmissions occur.

Security readout for executives and security teams

Affected Asterisk systems can reveal whether SIP account names exist when remote requests are invalid. This is information disclosure, not direct takeover, but exposed voice systems could become easier to target for password guessing or fraud. Exposure is most likely where affected Asterisk SIP services are reachable from untrusted networks, especially internet-facing PBX, VoIP gateway, or remote-phone deployments. Treat as a targeted-risk reduction item for exposed voice infrastructure. Prioritize remediation on internet-facing Asterisk systems or environments with weak SIP credential hygiene. Mitigation focus: Upgrade Asterisk Open Source to 1.8.20.2, 10.12.2, 11.2.2, or later where applicable.; Upgrade Certified Asterisk to 1.8.15-cert2 or later.; Upgrade Asterisk Business Edition C.3.x to C.3.8.1 or later..
