Technical Description

Multiple vulnerabilities have been identified in SiteBar, which could be exploited by attackers to disclose sensitive information or execute arbitrary comands and scripting code.

The first issue is caused by input validation errors in the "translator.php" script when processing the "lang" and "dir" parameters, which could be exploited by attackers to disclose the contents of arbitrary files.

The second vulnerability is caused by an input validation error in the "translator.php" script when processing the "value" and "edit" parameters, which could be exploited by attackers to inject and execute arbitrary PHP code with the privileges of the web server.

The third issue is caused by input validation errors in the "integrator.php", "command.php" and "index.php" scripts when processing user-supplied parameters, which could be exploited by malicious uses to cause arbitrary scripting code to be executed by the user's browser in the security context of an affected Web site.

The fourth weakness if caused by an error in the "command.php" script when processing the "forward" parameter in a Log In action, which could be exploited by attackers to redirect users to arbitrary web sites.
