CVE-2025-59834 is a critical command injection vulnerability affecting the srmorete adb-mcp server, a Model Context Protocol (MCP) server used for interacting with Android devices via the Android Debug Bridge (ADB). Versions 0.1.0 and earlier of adb-mcp contain improper neutralization of special elements in command inputs, classified under CWE-77 and CWE-78, which relate to command injection flaws. This vulnerability allows an unauthenticated attacker to execute arbitrary system commands remotely without any user interaction, due to the server's failure to properly sanitize or validate input before passing it to the underlying operating system shell. The vulnerability has a CVSS v3.1 base score of 9.8, indicating critical severity, with attack vector as network (AV:N), no required privileges (PR:N), no user interaction (UI:N), and full impact on confidentiality, integrity, and availability (C:H/I:H/A:H). Although no known exploits are reported in the wild yet, the high severity and ease of exploitation make this a significant risk. The issue has been addressed in a patch (commit 041729c), but no direct patch links are provided in the data. The vulnerability affects all deployments running vulnerable versions of adb-mcp, which is typically used in environments managing Android devices remotely, such as mobile device management (MDM) systems, development and testing infrastructures, and automated Android device farms.

For European organizations, the impact of this vulnerability can be severe. Organizations relying on adb-mcp for managing fleets of Android devices, including telecom operators, mobile app developers, and enterprises with BYOD policies, could face full system compromise on the servers running the vulnerable MCP service. This could lead to unauthorized data access, data exfiltration, disruption of device management operations, and potential lateral movement within corporate networks. Given the critical nature of the vulnerability and the lack of required authentication, attackers could remotely execute arbitrary commands, potentially deploying ransomware, stealing sensitive data, or disrupting services. The availability of Android devices for business-critical applications in sectors such as finance, healthcare, and government in Europe increases the risk profile. Additionally, the vulnerability could be leveraged in supply chain attacks targeting software development or testing environments that use adb-mcp, amplifying the potential damage.

European organizations should immediately identify and inventory all instances of adb-mcp in their environments. They must upgrade all vulnerable versions (<= 0.1.0) to the patched version containing commit 041729c or later. If an upgrade is not immediately possible, organizations should restrict network access to the MCP server, ideally isolating it behind firewalls or VPNs to limit exposure to untrusted networks. Implement strict input validation and command sanitization if custom integrations with adb-mcp exist. Employ network intrusion detection systems (NIDS) to monitor for suspicious command injection patterns targeting the MCP server. Regularly audit logs for anomalous command executions or unexpected process spawning. Additionally, enforce the principle of least privilege on the servers hosting adb-mcp, ensuring that even if exploited, the attacker’s ability to cause damage is limited. Finally, integrate this vulnerability into vulnerability management and incident response plans to ensure rapid detection and remediation.
