What is CVE-2022-30276?
CVE-2022-30276 is a high-severity missing authorization vulnerability in n/a, published on 26 Jul 2022. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
The Motorola MOSCAD and ACE line of RTUs through 2022-05-02 omit an authentication requirement. They feature IP Gateway modules which allow for interfacing between Motorola Data Link Communication (MDLC) networks (potentially over a variety of serial, RF and/or Ethernet links) and TCP/IP networks. Communication with RTUs behind the gateway is done by means of the proprietary IPGW protocol (5001/TCP). This protocol does not have any authentication features, allowing any attacker capable of communicating with the port in question to invoke (a subset of) desired functionality.
Weakness: CWE-306
