This vulnerability stems from improper validation of user-supplied input, allowing an unauthenticated, remote attacker to manipulate file paths via directory traversal sequences (e.g., ../). By sending a specially crafted URL request, an attacker can escape the intended application directories and write arbitrary files to the underlying operating system. This flaw, assigned a CVSS v3.1 score of 9.8, poses a significant risk to systems running these versions, as it may lead to full system compromise if an attacker is able to overwrite critical configuration or executable files.\u003c/p\u003e\n\u003ch2 id=\"attack-chain\"\u003eAttack Chain\u003c/h2\u003e\n\u003col\u003e\n\u003cli\u003eAttacker performs reconnaissance to identify internet-facing IBM App Connect Enterprise instances.\u003c/li\u003e\n\u003cli\u003eAttacker crafts an HTTP request targeting a vulnerable endpoint within the application.\u003c/li\u003e\n\u003cli\u003eAttacker injects directory traversal sequences (e.g., /../) into the URL request parameters or path.\u003c/li\u003e\n\u003cli\u003eThe application fails to sanitize the input, allowing the path to resolve outside the restricted base directory.\u003c/li\u003e\n\u003cli\u003eThe server process, executing with its current privileges, attempts to write the payload contained in the request to the target destination.\u003c/li\u003e\n\u003cli\u003eThe arbitrary file is successfully written to the system, enabling potential code execution or system modification.\u003c/li\u003e\n\u003c/ol\u003e\n\u003ch2 id=\"impact\"\u003eImpact\u003c/h2\u003e\n\u003cp\u003eSuccessful exploitation of this vulnerability allows for unauthorized file writes on the host system.
