Published Apr 10, 2024
CWE ID 120


CVE-2024-3119 is a buffer overflow vulnerability that affects all versions of sngrep since v0.4.2. This vulnerability is caused by improper handling of 'Call-ID' and 'X-Call-ID' SIP headers in the functions sip_get_callid and sip_get_xcallid in sip.c, as they use the strncpy function to copy header contents into fixed-size buffers without checking the data length. Exploiting this flaw can allow remote attackers to execute arbitrary code or cause a denial of service (DoS) by sending specially crafted SIP messages. The risk score for this vulnerability is 65, with a base severity of CRITICAL and a base score of 9.0 according to CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:H/A:H vector string. It is important for organizations using sngrep to update to a patched version as soon as possible to mitigate the potential danger posed by this vulnerability.
