Technical Description

Multiple vulnerabilities were identified in Tiny PHP Forum, which could be exploited by malicious users to gain knowledge of sensitive information, or perform directory traversal and cross site scripting attacks.

The first issue is due to an input validation error when displaying a message containing a specially crafted "link" URL, which could be exploited by attackers to execute arbitrary scripting code by tricking users into clicking on a malicious link.

The second flaw is due to a design error where user credentials are publicly accessible via the "users" directory, which may be exploited by malicious people to disclose sensitive information (e.g. encrypted passwords).

The third vulnerability is due to an input validation error in the "profile.php" script that does not properly handle a specially crafted "uname" parameter, which may be exploited by remote attackers to retrieve arbitrary files from a vulnerable system.
