Noroxi assessment

Priority: Monitor (action score 37/100)

  • Public proof-of-concept code exists (Exploit-DB); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 20.8% (FIRST EPSS); higher than 97.5% of all records.
  • No special conditions are required; it is repeatable.
  • Fixed version: asterisk (Debian:14) 1:1.2.16~dfsg-1; asterisk (Debian:3.1) 1:1.0.7.dfsg.1-2sarge5; asterisk (Debian:4.0) 1:1.2.13~dfsg-2etch1.

Low priority for now. Upgrade to asterisk (Debian:14) 1:1.2.16~dfsg-1; asterisk (Debian:3.1) 1:1.0.7.dfsg.1-2sarge5; asterisk (Debian:4.0) 1:1.2.13~dfsg-2etch1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

Asterisk 1.4 before 1.4.1 and 1.2 before 1.2.16 allows remote attackers to cause a denial of service (crash) by sending a Session Initiation Protocol (SIP) packet without a URI and SIP-version header, which results in a NULL pointer dereference.
