Short explanation

A heap-based buffer overflow vulnerability in the NoMachine mDNS parsing component allows network-adjacent attackers to execute arbitrary code without authentication. Patch status is currently unknown.

Why does it matter?

It poses a critical risk because it can be exploited over the network without authentication and enables code execution in the context of the service account.

What should be done?

NoMachine mDNS Heap-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of NoMachine. Authentication is not required to exploit this vulnerability. The specific flaw exists within the parsing of mDNS resource records. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of the service account. Was ZDI-CAN-30982.
