Filed under: — Aviran Mordo @ 10:04 am

A scripting error in Adobe’s website gave outsiders broad access to internal files on the company’s webserver that could prove valuable to malicious hackers trying to penetrate its security.

An Adobe spokesman said company engineers have plugged the leak, but couldn’t say when or how long the error had exposed site internals.

The flaw, known as a directory traversal, has serious implications for the security of Adobe’s site because it effectively gave web surfers the same permissions to read files afforded Adobe’s web application.

The interception of the key could make it easier for malicious hackers to spoof trusted portions of Adobe’s site.
