CVE-2007-3010

CVE-2007-3010 is a command execution flaw in masterCGI, a component of the Unified Maintenance Tool in the Alcatel OmniPCX Enterprise Communication Server. Because the CGI fails to properly validate user-supplied input (CWE-20), a remote attacker can send crafted requests to the web-based maintenance interface and inject arbitrary operating system commands, which are executed on the PBX server. Successful exploitation yields remote code execution on the communication server, giving attackers a foothold on a Linux-based edge device that could be used for further compromise, lateral movement into the voice network, or, per recent botnet trends, conscription into proxy botnets. Any organization running an Alcatel OmniPCX Enterprise communication server with the Unified Maintenance Tool reachable is affected. The flaw is listed in CISA's Known Exploited Vulnerabilities catalog (added 2022-04-15) with a very high 97.4% EPSS score, indicating active in-the-wild exploitation, though no public proof-of-concept code is known.

What to do: Apply updates per vendor instructions (Alcatel/Aastra/Alcatel-Lucent Enterprise maintenance releases) as required by CISA's KEV catalog. Until patched, restrict access to the Unified Maintenance Tool web interface (masterCGI) to trusted management networks only, e.g., via firewall or ACL rules, and avoid exposing it to the internet. Given recent Mirai-based botnets targeting Linux edge devices, audit OmniPCX servers for signs of compromise such as unexpected processes or outbound proxy (SOCKS5) traffic.
