ScriptAlias directive allows remote CGI script access
| http-scriptalias (332) |  Low Risk |
Description:
The ScriptAlias directive creates a virtual directory on your server. Any accesses to that virtual directory is satisfied by returning the output of a CGI server script in that directory. Configuring a Web server with a ScriptAlias Directive specifying a directory under DocumentRoot can open a vulnerability on some Web servers, allowing a remote attacker to view the source of CGI scripts on the Web server. This action may allow a remote attacker to gain access to proprietary CGI code or more easily determine vulnerabilities in existing CGI scripts on a computer.
Consequences:
Obtain Information
Remedy:
Affected sites should move ScriptAlias directories out of the DocumentRoot or upgrade your server to a version that securely handles ScriptAlias directives.
