Some vulnerabilities have been discovered in eTicket, which can be exploited by malicious people to conduct script insertion, cross-site scripting, and SQL injection attacks, and by malicious users to conduct SQL injection attacks.
1) Input passed via the "Name" and "Subject" parameters when opening a ticket is not properly sanitised before being stored. This can be exploited to inject arbitrary HTML and script code, which is then executed in a user's browser session in context of an affected site when the malicious ticket is viewed.
2) Input passed to the "s" parameter in view.php is not properly sanitised before being returned to a user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.
Successful exploitation requires that the target user is logged in or e.g. follows a malicious link and logs in.
3) Input passed to the "status" parameter in search.php is not properly sanitised before being used in SQL queries. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.
4) Input passed to the "msg" and "password" parameters in admin.php is not properly sanitised before being used in SQL queries. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.
Successful exploitation requires administrator privileges, but this can be bypassed via e.g. cross-site request forgery attacks.
The vulnerabilities are confirmed in version 22.214.171.124. Other versions may also be affected.
Solution: Fixed in version 1.5.6-RC4. Filter malicious characters and character sequences in a web proxy.
