CVE-2024-3119: Stack-Buffer Overflow in 'Call-ID' and 'X-Call-ID' SIP Header Processing in sngrep

• Severity: critical (CVSS 9.8 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 1.8% probability of exploitation in the next 30 days
• Public exploit or detection template: none known
• Published: 2024-04-10 · updated 2026-06-17
• Weakness: CWE-120

Description

A buffer overflow vulnerability exists in all versions of sngrep since v0.4.2, due to improper handling of 'Call-ID' and 'X-Call-ID' SIP headers. The functions sip_get_callid and sip_get_xcallid in sip.c use the strncpy function to copy header contents into fixed-size buffers without checking the data length. This flaw allows remote attackers to execute arbitrary code or cause a denial of service (DoS) through specially crafted SIP messages.

Affected products

• irontec sngrep: from 0.4.2 before 1.8.1 — fixed in 1.8.1

How to fix

Upgrade to a fixed version: irontec sngrep 1.8.1. Check the vendor advisory for mitigations.
