NGINX HTTP/3 QUIC vulnerability (CVE-2024-31079)
CVE-2024-31079 is a medium severity vulnerability affecting NGINX Plus and NGINX OSS when configured with the HTTP/3 QUIC module. Specifically crafted HTTP/3 requests, timed during the connection draining process, can cause NGINX worker processes to terminate or lead to other potential impacts. Exploitation requires precise timing that attackers have limited control or visibility over. A patch is available for affected versions.
AI Analysis
Technical Summary
This vulnerability in NGINX HTTP/3 QUIC module allows specially timed HTTP/3 requests during connection draining to cause worker process termination or other impacts. The attack complexity is high due to the need for precise timing during connection draining, which attackers cannot easily observe or influence. The affected versions are NGINX versions from 1.25.0 up to but not including 1.26.1. No CVSS score is provided, but the severity is assessed as medium. A patch is available to address this issue.
Potential Impact
Successful exploitation can cause termination of NGINX worker processes, potentially disrupting service availability. Other unspecified impacts may also occur. However, the attack requires precise timing during connection draining, limiting the likelihood and ease of exploitation.
Mitigation Recommendations
A patch is available for this vulnerability. Users should upgrade NGINX to version 1.26.1 or later to remediate the issue. No additional mitigation steps are indicated by the vendor advisory.
