PJSIP, as used in Asterisk Open Source 13.x before 13.15.1 and 14.x before 14.4.1, Certified Asterisk 13.13 before 13.13-cert4, and other products, allows remote attackers to cause a denial of service (buffer overflow and application crash) via a SIP packet with a crafted CSeq header in conjunction with a Via header that lacks a branch parameter.

Security readout for executives and security teams

This flaw can let a remote party crash vulnerable Asterisk deployments that use PJSIP by sending a specially malformed SIP message. The business impact is availability: phones, call routing, and SIP-dependent services may stop until the application is recovered. The supplied sources do not show data theft or confirmed active exploitation. Exposure is most likely where affected Asterisk 13.x, 14.x, or Certified Asterisk 13.13 builds use PJSIP and accept SIP traffic from untrusted networks. The CVE text also says “other products,” but the supplied bundle does not identify them. Prioritize remediation for externally reachable or business-critical voice systems. This is not presented as a data breach issue, but a remote crash in telephony infrastructure can disrupt operations and customer communications. Mitigation focus: Upgrade Asterisk Open Source 13.x to 13.15.1 or later.; Upgrade Asterisk Open Source 14.x to 14.4.1 or later.; Upgrade Certified Asterisk 13.13 to 13.13-cert4 or later..
