NVD-CWE-noinfoPublished: February 22, 2018· Updated: Jun 17, 2026

6.5

CVSS v3.1

Official Description

An issue was discovered in Asterisk through 13.19.1, 14.x through 14.7.5, and 15.x through 15.2.1, and Certified Asterisk through 13.18-cert2. res_pjsip allows remote authenticated users to crash Asterisk (segmentation fault) by sending a number of SIP INVITE messages on a TCP or TLS connection and then suddenly closing the connection.

Technical Analysis

CVE-2018-7286 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.

A successful exploit results in availability disruption (denial of service), with a CVSS base score of 6.5.

A proof-of-concept (PoC) exploit exists for CVE-2018-7286. While not yet confirmed in active campaigns, the availability of PoC code increases exploitation risk substantially.
