Name of the Vulnerable Software and Affected Versions COMFAST CF-WR623N Router firmware versions V2.3.0.1 and before

Description The issue is related to Incorrect Access Control, where improper authentication allows requests to be made to back-end scripts without a valid session or authentication. This means that unauthorized access can be gained to the router's back-end scripts, potentially leading to further exploitation.

Recommendations For COMFAST CF-WR623N Router firmware versions V2.3.0.1 and before, consider restricting access to back-end scripts until a patch is available. As a temporary workaround, disabling any unnecessary features or scripts that do not require immediate access can help minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
