Multiple vulnerabilities in MonkeyCMS version 5.3.10, and possibly other versions, could allow an unauthenticated, remote attacker to execute arbitrary code or conduct SQL injection attacks.
The vulnerabilities are due to insufficient sanitization of user-supplied input by the affected software. An attacker could exploit these vulnerabilities by sending crafted SQL queries to the targeted device. Successful exploitation could allow the attacker to view, add, or modify information in the back-end database or manipulate SQL queries by injecting and executing arbitrary SQL code.
Proof-of-concept code that exploits these vulnerabilities is publicly available.
The vendor has not confirmed the vulnerability and has not released updated software.

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.
