Cross-site scripting (XSS) vulnerability in proxyftp.c in the modproxyftp module in Apache 2.0.63 and earlier, and modproxyftp.c in the modproxy_ftp module in Apache 2.2.9 and earlier 2.2 versions, allows remote attackers to inject arbitrary web script or HTML via a wildcard in the last directory component in the pathname in an FTP URI.
