This vulnerability exists in the \u003ccode\u003ebuild_project/run_tests\u003c/code\u003e function within the \u003ccode\u003esrc/index.ts\u003c/code\u003e file of the MCP Interface component. An attacker can remotely inject operating system commands by manipulating the Request argument. The vulnerability has been publicly disclosed, increasing the risk of exploitation. The vendor has been notified but has not yet responded, leaving systems exposed. This poses a significant risk to organizations using this software, as successful exploitation allows complete system compromise.\u003c/p\u003e\n\u003ch2 id=\"attack-chain\"\u003eAttack Chain\u003c/h2\u003e\n\u003col\u003e\n\u003cli\u003eThe attacker identifies a vulnerable instance of PolarVista xcode-mcp-server 1.0.0.\u003c/li\u003e\n\u003cli\u003eThe attacker crafts a malicious request targeting the \u003ccode\u003ebuild_project/run_tests\u003c/code\u003e function in \u003ccode\u003esrc/index.ts\u003c/code\u003e.\u003c/li\u003e\n\u003cli\u003eThe malicious request includes an OS command injection payload within the Request argument.\u003c/li\u003e\n\u003cli\u003eThe application fails to properly sanitize or validate the Request argument.\u003c/li\u003e\n\u003cli\u003eThe application executes the injected OS command on the server.\u003c/li\u003e\n\u003cli\u003eThe attacker gains arbitrary code execution on the server, potentially escalating privileges.\u003c/li\u003e\n\u003cli\u003eThe attacker installs malware, such as a reverse shell, to maintain persistent access.\u003c/li\u003e\n\u003cli\u003eThe attacker performs reconnaissance, lateral movement, and data exfiltration within the compromised network.\u003c/li\u003e\n\u003c/ol\u003e\n\u003ch2 id=\"impact\"\u003eImpact\u003c/h2\u003e\n\u003cp\u003eSuccessful exploitation of this vulnerability allows a remote attacker to execute arbitrary operating system commands on the affected server.
