Name of the Vulnerable Software and Affected Versions MikroTik RouterOS versions prior to 6.42.7 MikroTik RouterOS versions prior to 6.40.9

Description The issue is caused by memory corruption errors in the HTTP server of MikroTik RouterOS, specifically in the /nova/bin/www endpoint. An authenticated remote attacker can exploit this by rapidly authenticating and disconnecting, leading to a crash of the HTTP server.

Recommendations For versions prior to 6.42.7, update to version 6.42.7 or later. For versions prior to 6.40.9, update to version 6.40.9 or later. As a temporary workaround, consider restricting access to the /nova/bin/www endpoint to minimize the risk of exploitation.
