CVE-2026-29170 is a cross-site scripting (XSS) vulnerability in Apache HTTP Server's mod_proxy_ftp module affecting versions 2.4.67 and earlier. The issue occurs during HTML directory list generation when listing FTP directory contents via forward or reverse proxy. This vulnerability allows an attacker to inject malicious scripts that could be executed in the context of the user's browser. The Apache Software Foundation recommends upgrading to version 2.4.68 to address this vulnerability.
AI Analysis
Technical Summary
This vulnerability involves improper neutralization of input during web page generation (CWE-79) in the mod_proxy_ftp module of Apache HTTP Server. Specifically, when the server lists FTP directory contents through forward or reverse proxy configurations, it generates HTML directory listings that do not properly sanitize input, enabling cross-site scripting attacks. The vulnerability affects all Apache HTTP Server versions up to and including 2.4.67. The issue is fixed in version 2.4.68.
Potential Impact
Successful exploitation of this vulnerability could allow an attacker to execute arbitrary scripts in the context of the victim's browser, potentially leading to information disclosure or other client-side impacts. The CVSS v3.1 base score is 6.1 (medium severity), reflecting network attack vector, low attack complexity, no privileges required, user interaction required, scope changed, and low impact on confidentiality and integrity with no impact on availability.
Mitigation Recommendations
Users should upgrade Apache HTTP Server to version 2.4.68 or later, where this vulnerability is fixed. No other mitigations are specified. Patch status is confirmed by the vendor recommendation to upgrade to 2.4.68.
