Individual Definition in a New Window
Information Leak Through Source Code
Status: Incomplete

Description
Summary

Source code on a web server often contains sensitive information and should generally not be accessible to users.

Extended Description

There are situations where it is critical to remove source code from an area or server. For example, obtaining Perl source code on a system allows an attacker to view the logic of the script and extract extremely useful information such as code bugs or logins and passwords.

Potential Mitigations

Recommendations include removing this script from the web server and moving it to a location not accessible from the Internet.
