The vulnerability exists in versions 7.0.3 up to Interim Fix 021, 7.1.0 up to Interim Fix 009, and 7.2.0 up to Interim Fix 001. An attacker can exploit this flaw by updating server property files, which can lead to unauthorized access to the application and potential complete system compromise. This vulnerability poses a significant risk to organizations using the affected versions of IBM ELM, as it could allow attackers to bypass authentication mechanisms and gain complete control over the application.\u003c/p\u003e\n\u003ch2 id=\"attack-chain\"\u003eAttack Chain\u003c/h2\u003e\n\u003col\u003e\n\u003cli\u003eThe attacker identifies a vulnerable IBM Engineering Lifecycle Management server exposed to the internet.\u003c/li\u003e\n\u003cli\u003eThe attacker crafts a malicious request to update server property files.
