| Doc Text: |
A flaw was found in httpd. When configured as a forward proxy using the mod_proxy_ftp module, the server improperly validates the network address returned in a File Transfer Protocol (FTP) passive mode (PASV) response. A malicious FTP server can exploit this flaw by returning a crafted reply, forcing the proxy to establish a data connection to an arbitrary third-party host. This issue may allow an attacker to initiate unauthorized network connections or probe internal systems that are otherwise inaccessible.
