Multiple vulnerabilities in RiteCMS version 1.0.0, and possibly other versions, could allow an unauthenticated, remote attacker to conduct cross-site scripting (XSS) and cross-site request forgery (CSRF) attacks.
The vulnerabilities are due to insufficient validation of user-supplied input by the affected software. An attacker could exploit these vulnerabilities by convincing a user to follow a malicious URL that is designed to submit crafted input to the vulnerable application. A successful exploit could allow the attacker to execute arbitrary script or HTML code in the user's browser session under the context of the affected site, which could allow the attacker to access sensitive browser-based information—such as cookie-based authentication credentials—or perform other unauthorized actions.
Proof-of-concept code that exploits this vulnerability is publicly available.
Users should verify that unsolicited links are safe to follow.

Administrators are advised to implement an intrusion prevention system (IPS) or intrusion detection system (IDS) to help detect and prevent attacks that attempt to exploit this vulnerability.
The vendor has not confirmed the vulnerability and has not released updated software.
