The vulnerability originates from improper neutralization of special elements in file paths, allowing an unauthenticated remote attacker to perform a relative path traversal attack. By supplying specially crafted input to vulnerable application endpoints, an attacker can bypass directory restrictions to access and download arbitrary files from the underlying host filesystem. This flaw poses a significant risk to confidentiality, as it could permit the unauthorized retrieval of configuration files, credentials, or other sensitive system data. Defenders should prioritize patching affected instances to the latest available version provided by 4MOSAn Security Technology.\u003c/p\u003e\n\u003ch2 id=\"attack-chain\"\u003eAttack Chain\u003c/h2\u003e\n\u003col\u003e\n\u003cli\u003eThe attacker performs reconnaissance to identify internet-facing 4MOSAn Management Center instances.\u003c/li\u003e\n\u003cli\u003eThe attacker sends an unauthenticated HTTP request to a vulnerable application endpoint.\u003c/li\u003e\n\u003cli\u003eThe request includes a manipulated parameter containing directory traversal sequences (e.g., ../../../).\u003c/li\u003e\n\u003cli\u003eThe application processes the input without sufficient validation of the requested file path.\u003c/li\u003e\n\u003cli\u003eThe server-side code resolves the traversal path to access files outside of the intended directory.\u003c/li\u003e\n\u003cli\u003eThe application reads the contents of the targeted system file and includes it in the HTTP response body.\u003c/li\u003e\n\u003cli\u003eThe attacker receives the sensitive file content, completing the unauthorized data exfiltration.\u003c/li\u003e\n\u003c/ol\u003e\n\u003ch2 id=\"impact\"\u003eImpact\u003c/h2\u003e\n\u003cp\u003eSuccessful exploitation allows unauthenticated attackers to read any file on the server accessible to the web application process.
