CVE-2025-11285 is an OS command injection vulnerability identified in samanhappy MCPHub, a software product used in certain server management or orchestration contexts. The vulnerability resides in the source file src/controllers/serverController.ts, where the application improperly handles user-supplied input for command and argument parameters. This improper sanitization allows an attacker to inject arbitrary operating system commands that the server executes with the privileges of the MCPHub process. The vulnerability can be exploited remotely without requiring authentication or user interaction, making it highly accessible to attackers. The CVSS 4.0 base score is 5.3 (medium), reflecting the ease of remote exploitation but limited privileges required (low privileges) and limited impact on confidentiality, integrity, and availability (low impact each). The vendor was notified early but has not issued any patches or advisories, and public exploit code is available, increasing the risk of exploitation. No known exploits in the wild have been reported yet, but the presence of public exploit code means attackers can readily develop attacks. The lack of vendor response and patch availability means organizations must rely on compensating controls. The vulnerability affects all MCPHub versions from 0.9.0 through 0.9.10, which are currently in use. The attack vector is network-based, and the vulnerability does not require user interaction, increasing its threat potential. The vulnerability’s impact includes potential unauthorized command execution leading to data breaches, service disruption, or further network compromise.

For European organizations, exploitation of CVE-2025-11285 could lead to unauthorized remote code execution on servers running MCPHub, potentially resulting in data theft, service outages, or lateral movement within networks. Organizations in sectors such as critical infrastructure, finance, telecommunications, and government that rely on MCPHub for server management or orchestration are at particular risk. The vulnerability’s ability to be exploited remotely without authentication lowers the barrier for attackers, increasing the likelihood of compromise. Given the vendor’s lack of response and absence of patches, organizations face prolonged exposure. The medium severity rating suggests moderate impact, but real-world consequences could escalate if attackers leverage this vulnerability as a foothold for broader attacks. The availability of public exploit code further raises the risk of automated or opportunistic attacks targeting European entities. Disruption or compromise of MCPHub-managed systems could affect operational continuity and data confidentiality, with potential regulatory and reputational consequences under GDPR and other European cybersecurity regulations.

Since no official patch or update is available from the vendor, European organizations should implement immediate compensating controls. These include restricting network access to MCPHub management interfaces using firewalls or VPNs to limit exposure to trusted administrators only. Employ strict input validation and sanitization proxies or web application firewalls (WAFs) that can detect and block command injection patterns targeting MCPHub endpoints. Monitor logs and network traffic for unusual command execution attempts or anomalous behavior indicative of exploitation attempts. Consider isolating MCPHub servers in segmented network zones with limited connectivity to critical assets. If feasible, temporarily disable or restrict the vulnerable functionality within MCPHub until a patch is released. Engage in threat hunting activities focused on this vulnerability and update incident response plans to include detection and remediation steps for CVE-2025-11285 exploitation. Maintain close monitoring of vendor communications for any forthcoming patches or advisories. Finally, consider alternative software solutions if MCPHub is critical and no timely patch is expected.
