Improper validation of FTP PASV reply address in mod_proxy_ftp in Apache Software Foundation Apache HTTP Server through 2.4.68 on all platforms… (CVE-2026-63045)
A vulnerability in the Apache HTTP Server's mod_proxy_ftp module through version 2.4.68 allows improper validation of the FTP PASV reply address. This flaw enables an untrusted FTP server, when used in forward proxy configurations, to cause the proxy to open a data connection to an arbitrary third-party host via a crafted PASV response. The issue is fixed in version 2.4.69.
AI Analysis
Technical Summary
The Apache HTTP Server mod_proxy_ftp module improperly validates the FTP PASV reply address in versions up to 2.4.68 on all platforms. This vulnerability allows an attacker controlling an untrusted FTP server to manipulate the PASV response, causing the proxy to open a data connection to an arbitrary third-party host. This behavior occurs in forward proxy configurations. The vulnerability is addressed by upgrading to version 2.4.69.
Potential Impact
An attacker controlling an untrusted FTP server can exploit this vulnerability to cause the proxy to initiate connections to arbitrary third-party hosts. This could potentially be used to bypass network restrictions or facilitate indirect attacks on other systems. No further impact details are provided.
Mitigation Recommendations
Users should upgrade Apache HTTP Server to version 2.4.69, which contains the official fix for this vulnerability.
