Apache HTTP Server UTF-7 cross-site scripting

apache-utf7-xss (36586)

Medium Risk

Description:

Apache HTTP Server is vulnerable to cross-site scripting, caused by improper validation of user-supplied input by mod_autoindex.c. A remote attacker could exploit this vulnerability using the UTF-7 charset option to inject malicious script into a Web page which would be executed in a victim's Web browser within the security context of the hosting Web site, once the page is viewed. An attacker could use this vulnerability to steal the victim's cookie-based authentication credentials.

NOTE: it could be argued that this issue is due to a design limitation of browsers that attempt to perform automatic content type detection.
