OpenIDM version 4.0.0 and 4.5.0 contains a reflected cross-site scripting vulnerability that affects the administrative user interface. This vulnerability exists in the authzRoles script located under managed/user/ and can be exploited through the _sortKeys parameter. The flaw allows an attacker to inject malicious scripts into the web application by manipulating the parameter value in the URL, which is then reflected back to the user without proper sanitization or encoding.
The technical implementation of this vulnerability stems from insufficient input validation and output encoding within the Admin UI components. When the system processes the _sortKeys parameter, it fails to properly sanitize user-supplied input before incorporating it into dynamic web content. This creates an opportunity for attackers to execute arbitrary JavaScript code within the context of a victim's browser session. The reflected nature of the vulnerability means that the malicious payload is delivered and executed in response to a crafted request rather than being stored on the server.
The operational impact of this vulnerability is significant as it allows attackers to potentially hijack user sessions, steal sensitive authentication tokens, or perform unauthorized actions within the administrative interface. An attacker could craft malicious URLs that, when clicked by an authenticated administrator, would execute malicious scripts in the victim's browser. This could lead to privilege escalation, data theft, or complete compromise of the identity management system. The vulnerability affects the core administrative functionality of OpenIDM, making it particularly dangerous for organizations that rely on the platform for identity and access management.
This vulnerability maps to CWE-79 which specifically addresses cross-site scripting flaws in web applications. The attack pattern aligns with the ATT&CK technique T1059.007 for Scripting, where adversaries use scripting languages to execute malicious code. The reflected XSS nature also corresponds to ATT&CK technique T1203 for Exploitation for Client Execution, where adversaries leverage client-side vulnerabilities to execute code. Organizations should implement proper input validation, output encoding, and Content Security Policy headers to mitigate this risk. The recommended remediation involves updating to a patched version of OpenIDM, implementing proper parameter sanitization, and deploying web application firewalls to detect and block malicious requests targeting this vulnerability.
