The vulnerability resides within the \u003ccode\u003esrc/aider_mcp_server/server.py\u003c/code\u003e file of the \u003ccode\u003eaider_ai_code\u003c/code\u003e component. It stems from improper handling of the \u003ccode\u003erelative_editable_files\u003c/code\u003e argument, which can be manipulated by a remote attacker to inject and execute arbitrary commands on the system. Exploitation is possible remotely, and a proof-of-concept exploit has been published, increasing the risk of widespread attacks. The project follows a rolling release model, so specific patched versions are not available, making mitigation challenging.\u003c/p\u003e\n\u003ch2 id=\"attack-chain\"\u003eAttack Chain\u003c/h2\u003e\n\u003col\u003e\n\u003cli\u003eAttacker identifies a vulnerable instance of \u003ccode\u003eaider-mcp-server\u003c/code\u003e running a version up to commit \u003ccode\u003eb2516fa466d0d851932da92ee6d0e66946db9efc\u003c/code\u003e.\u003c/li\u003e\n\u003cli\u003eAttacker crafts a malicious request targeting the vulnerable functionality in \u003ccode\u003esrc/aider_mcp_server/server.py\u003c/code\u003e.\u003c/li\u003e\n\u003cli\u003eThe crafted request includes a payload within the \u003ccode\u003erelative_editable_files\u003c/code\u003e argument designed to inject shell commands.\u003c/li\u003e\n\u003cli\u003eThe \u003ccode\u003eaider-mcp-server\u003c/code\u003e processes the request and improperly sanitizes the \u003ccode\u003erelative_editable_files\u003c/code\u003e argument.\u003c/li\u003e\n\u003cli\u003eThe unsanitized argument is passed to a function that executes shell commands.\u003c/li\u003e\n\u003cli\u003eThe injected commands are executed on the server with the privileges of the \u003ccode\u003eaider-mcp-server\u003c/code\u003e process.\u003c/li\u003e\n\u003cli\u003eAttacker gains arbitrary code execution on the server.\u003c/li\u003e\n\u003cli\u003eThe attacker can then perform actions such as installing malware, accessing sensitive data, or pivoting to other systems.\u003c/li\u003e\n\u003c/ol\u003e\n\u003ch2 id=\"impact\"\u003eImpact\u003c/h2\u003e\n\u003cp\u003eSuccessful exploitation of this command injection vulnerability allows a remote attacker to execute arbitrary commands on the affected server. This can lead to complete system compromise, including data theft, malware installation, and denial of service. Given that an exploit is publicly available, the risk of exploitation is significantly elevated. The lack of versioned releases makes patching and mitigation more complex, potentially affecting any instance running a version prior to a fix being implemented.\u003c/p\u003e\n\u003ch2 id=\"recommendation\"\u003eRecommendation\u003c/h2\u003e\n\u003cul\u003e\n\u003cli\u003eInspect \u003ccode\u003eaider-mcp-server\u003c/code\u003e logs for suspicious activity related to requests targeting \u003ccode\u003esrc/aider_mcp_server/server.py\u003c/code\u003e and the handling of \u003ccode\u003erelative_editable_files\u003c/code\u003e to detect potential exploitation attempts.\u003c/li\u003e\n\u003cli\u003eDeploy the provided Sigma rule to detect command execution originating from the \u003ccode\u003eaider-mcp-server\u003c/code\u003e process.\u003c/li\u003e\n\u003cli\u003eMonitor network connections originating from the \u003ccode\u003eaider-mcp-server\u003c/code\u003e for unexpected outbound activity.\u003c/li\u003e\n\u003c/ul\u003e\n","date_modified":"2024-01-02T12:00:00Z","date_published":"2024-01-02T12:00:00Z","id":"https://feed.craftedsignal.io/briefs/2024-01-02-aider-mcp-command-injection/","summary":"A command injection vulnerability (CVE-2026-7157) exists in disler aider-mcp-server, allowing remote attackers to execute arbitrary commands by manipulating the relative_editable_files argument in the aider_ai_code component's server.py.","title":"disler aider-mcp-server Command Injection Vulnerability (CVE-2026-7157)","url":"https://feed.craftedsignal.io/briefs/2024-01-02-aider-mcp-command-injection/"}],"language":"en","title":"CraftedSignal Threat Feed - Disler","version":"https://jsonfeed.org/version/1.1"}
