Official description
An issue was discovered in za-internet C-MOR Video Surveillance 5.2401 and 6.00PL01. Due to insufficient input validation, the C-MOR web interface is vulnerable to OS command injection attacks. It was found out that different functionality is vulnerable to OS command injection attacks, for example for generating new X.509 certificates, or setting the time zone. These OS command injection vulnerabilities in the script generatesslreq.pml can be exploited as a low-privileged authenticated user to execute commands in the context of the Linux user www-data via shell metacharacters in HTTP POST data (e.g., the city parameter). The OS command injection vulnerability in the script settimezone.pml or setdatetime.pml (e.g., via the year parameter) requires an administrative user for the C-MOR web interface. By also exploiting a privilege-escalation vulnerability, it is possible to execute commands on the C-MOR system with root privileges.

The underlying weakness: Improper Validation of Unsafe Equivalence in Input
The product receives an input value that is used as a resource identifier or other type of reference, but it does not validate or incorrectly validates that the input is equivalent to a potentially-unsafe value.
