Advisory Content (Page 1 of 3)[ 1 ] [ 2 ] [ 3 ]

Description:
Multiple vulnerabilities have been reported in Geeklog allowing malicious people to conduct Cross Site Scripting and retrieve password hashes.

Geeklog stores the password hash in cookies to verify if users are logged in. This could expose the password if Cross Site Scripting vulnerabilities exist.

Logged in users do not need to supply the old password to change it. This is not regarded as a vulnerability, but it is an inappropriate way to handle password changes.

While most functions in the forum do filter out normal "<SCRIPT>" tags, it is still possible to inject script using HTML parameters.

Example:
<img src="javascript:alert()">
