CVE-2007-3011 in ServerView
Summary
by MITRE
The DBAsciiAccess CGI Script in the web interface in Fujitsu-Siemens Computers ServerView before 4.50.09 allows remote attackers to execute arbitrary commands via shell metacharacters in the Servername subparameter of the ParameterList parameter.

The vulnerability identified as CVE-2007-3011 represents a critical command injection flaw within the ServerView management interface of Fujitsu-Siemens Computers systems. This issue affects versions prior to 4.50.09 and specifically targets the DBAsciiAccess CGI script that handles web-based server management operations. The vulnerability stems from inadequate input validation mechanisms that fail to properly sanitize user-supplied data before processing it within the system's command execution pathways. Attackers can exploit this weakness by crafting malicious payloads containing shell metacharacters that are subsequently interpreted and executed by the underlying operating system, thereby gaining unauthorized control over the affected server.
The technical implementation of this vulnerability occurs through the manipulation of the ParameterList parameter, specifically targeting the Servername subparameter within the DBAsciiAccess CGI script. When a remote attacker submits a specially crafted request containing shell metacharacters such as semicolons, ampersands, or backticks within the Servername field, the system processes these inputs without proper sanitization. This failure to validate and escape input data creates a direct pathway for command injection attacks, allowing malicious actors to execute arbitrary system commands with the privileges of the web server process. The vulnerability aligns with CWE-77, which specifically addresses command injection flaws, and demonstrates how insufficient input filtering can lead to complete system compromise.
The operational impact of this vulnerability extends beyond simple unauthorized command execution to encompass full system compromise and potential data exfiltration. An attacker who successfully exploits this vulnerability can execute commands such as file system traversal, privilege escalation, network scanning, or even establish persistent backdoors within the affected environment. The implications are particularly severe in server management contexts where the web interface serves as a critical access point for system administrators. This vulnerability essentially provides attackers with a gateway to the underlying server infrastructure, potentially enabling them to manipulate system configurations, access sensitive data, or disrupt critical services. The attack surface is amplified by the fact that this is a remote exploit, meaning no local access or authentication is required to initiate the attack.
Mitigation strategies for this vulnerability must address both immediate remediation and long-term security hardening measures. The primary recommendation involves upgrading the ServerView software to version 4.50.09 or later, which contains the necessary patches to address the input validation flaws. Organizations should also implement comprehensive input validation at multiple layers including web application firewalls, proxy servers, and direct application-level sanitization. The implementation of proper parameterized queries and input escaping mechanisms should be enforced throughout the application codebase to prevent similar vulnerabilities from emerging. Additionally, security monitoring should be enhanced to detect anomalous command execution patterns and unauthorized access attempts. This vulnerability demonstrates the importance of following secure coding practices and adheres to ATT&CK technique T1059.001 for command and scripting interpreter, highlighting how unvalidated inputs can lead to arbitrary code execution. Organizations should also consider implementing network segmentation and principle of least privilege access controls to limit the potential impact of successful exploitation attempts.
