CVE-2025-11491 is an OS command injection vulnerability identified in the DesktopCommanderMCP software developed by wonderwhy-er, affecting all versions up to 0.2.13. The vulnerability resides specifically in the CommandManager function within the source file src/command-manager.ts. An attacker can manipulate inputs to this function to inject arbitrary operating system commands, which the software then executes. This flaw can be exploited remotely without requiring user interaction or prior authentication, making it accessible to a wide range of attackers. The attack complexity is low, meaning exploitation does not require advanced skills or conditions. The vulnerability impacts confidentiality, integrity, and availability by allowing attackers to execute malicious commands that could lead to data theft, system compromise, or denial of service. Although no active exploitation has been reported, the public disclosure of exploit code increases the likelihood of attacks. The vulnerability does not require special privileges or user involvement, increasing its risk profile. The CVSS 4.0 base score is 5.3 (medium), reflecting the balance between ease of exploitation and the scope of impact. No official patches are linked yet, so mitigation currently relies on network-level controls and input sanitization. Organizations should monitor vendor communications for updates and prepare to deploy fixes promptly.

For European organizations, this vulnerability poses a significant risk especially to those using DesktopCommanderMCP in operational environments. Successful exploitation could allow attackers to execute arbitrary commands on affected systems, potentially leading to unauthorized data access, system manipulation, or disruption of services. This could impact critical sectors such as manufacturing, logistics, and IT services that rely on DesktopCommanderMCP for command management. The remote and unauthenticated nature of the vulnerability increases the attack surface, making it easier for threat actors to target European enterprises. Confidentiality breaches could expose sensitive business or personal data, while integrity violations might corrupt operational processes. Availability could be compromised if attackers execute commands that disrupt system functionality or cause denial of service. The public availability of exploit code raises the urgency for European organizations to act swiftly to prevent exploitation. The medium severity score suggests moderate but non-negligible risk, warranting prioritized remediation in environments where DesktopCommanderMCP is deployed.

1. Monitor wonderwhy-er's official channels for the release of security patches addressing CVE-2025-11491 and apply them immediately upon availability. 2. Until patches are available, restrict network access to DesktopCommanderMCP services using firewalls or network segmentation to limit exposure to trusted hosts only. 3. Implement strict input validation and sanitization on all inputs handled by the CommandManager function to prevent injection of malicious commands. 4. Employ application-layer firewalls or intrusion prevention systems capable of detecting and blocking command injection patterns targeting DesktopCommanderMCP. 5. Conduct thorough code reviews and security testing on custom integrations or scripts interacting with DesktopCommanderMCP to identify and remediate unsafe command execution. 6. Enforce the principle of least privilege for service accounts running DesktopCommanderMCP to minimize potential damage from exploitation. 7. Maintain comprehensive logging and monitoring of command execution activities to detect anomalous behavior indicative of exploitation attempts. 8. Educate IT and security teams about the vulnerability and ensure incident response plans include scenarios involving command injection attacks on this software.
