The vulnerability identified as CVE-2007-3010 affects the Unified Maintenance Tool component of Alcatel OmniPCX Enterprise Communication Server version R7.1 and earlier releases. This critical security flaw resides within the masterCGI functionality that handles administrative tasks through a web interface. The vulnerability specifically manifests when the system processes user input during ping operations, creating a path for remote code execution through improper input validation and sanitization mechanisms.
The technical root cause of this vulnerability stems from insufficient input validation within the ping functionality of the Unified Maintenance Tool. When a user parameter containing shell metacharacters is submitted during a ping action, the system fails to properly sanitize or escape these characters before processing. This allows attackers to inject malicious shell commands that get executed with the privileges of the web server process. The vulnerability directly maps to CWE-77 which describes improper neutralization of special elements used in a command, and CWE-94 which addresses improper control of generation of code. The attack vector is remote and requires no authentication, making it particularly dangerous for networked communication systems.
The operational impact of this vulnerability extends beyond simple command execution, as it provides attackers with complete control over the affected communication server. An attacker could leverage this vulnerability to gain unauthorized access to the system, escalate privileges, install backdoors, or conduct further reconnaissance within the network. The OmniPCX Enterprise Communication Server serves as a critical infrastructure component for enterprise communications, making this vulnerability particularly dangerous as it could disrupt business operations, compromise sensitive communication data, and potentially serve as a foothold for broader network infiltration. The vulnerability's presence in the maintenance tool interface means that even unauthenticated attackers could exploit it, significantly increasing the attack surface.
Mitigation strategies for this vulnerability should include immediate patching of the affected Alcatel OmniPCX Enterprise Communication Server to version R7.2 or later, which contains the necessary security fixes. Organizations should also implement network segmentation to limit access to the maintenance interfaces, deploy web application firewalls to filter suspicious input patterns, and conduct thorough network monitoring for unusual ping activity or command execution attempts. Additionally, administrators should disable unnecessary web interfaces and implement strict input validation policies for all user-supplied data. This vulnerability aligns with ATT&CK technique T1059.001 for command and script interpreter, and T1068 for exploit for privilege escalation, highlighting the need for comprehensive defensive measures across multiple attack surface areas.
