Title: IBM HTTP Server Source Code Disclosure Vulnerability

Severity: HIGH

Description:

IBM HTTP Server for the AS/400 is prone to an input validation error which makes it possible for a remote attacker to make a specially crafted web request which will display script source code.

If a '/' is appended to the end of a request for an existing script, then this will cause the script's source code to be displayed instead of executed.

This can be accomplished with the following web request:

http://www.targetserver.com/script.jsp/

There is a potential that this issue may result in sensitive information being disclosed to attackers, depending on the contents of the script source code.

*It has been reported that the source of this issue is due to WebSphere Application server 3.5.4. However this has not yet been confirmed by the vendor.

  • IBM HTTP Server 1.3.12.2
  • IBM HTTP Server 1.3.12.3
  • IBM HTTP Server 1.3.12.4
