Brendan Coles has discovered two security issues and a vulnerability in TestLink, which can be exploited by malicious people to conduct cross-site forgery attacks and disclose certain sensitive and system information.
1) The application allows users to perform certain actions via HTTP requests without performing proper validity checks to verify the requests. This can be exploited to e.g. create an arbitrary user with administrative privileges if a logged-in administrative user visits a malicious web site.
This vulnerability is confirmed in version 1.9.4. Other versions may also be affected.
2) The application does not properly restrict access to the audit logs in the logs directory and can be exploited to disclose the session identifiers of the logged-in users and e.g. gain administrative access to the application.
3) The application does not properly restrict access to the sysinfo.php script and can be exploited to disclose certain system information.
The security issues are confirmed in version 1.9.3. Prior versions may also be affected.
Solution: No official solution is currently available. Update to version 1.9.4 which fixes vulnerability #2 and #3.
