CVE-2019-18571 in RSA Identity Governance
Summary
by MITRE
The RSA Identity Governance and Lifecycle and RSA Via Lifecycle and Governance products prior to 7.1.1 P03 contain a reflected cross-site scripting vulnerability in the My Access Live module [MAL]. An authenticated malicious local user could potentially exploit this vulnerability by sending crafted URL with scripts. When victim users access the module through their browsers, the malicious code gets injected and executed by the web browser in the context of the vulnerable web application.

The RSA Identity Governance and Lifecycle platform version 7.1.1 P03 and earlier contains a critical reflected cross-site scripting vulnerability within its My Access Live module designated as MAL. This vulnerability represents a significant security weakness that allows authenticated attackers to inject malicious scripts into the web application through crafted URLs. The flaw specifically affects the web interface handling of user inputs within the My Access Live module, creating an environment where malicious code can be executed in the context of the victim's browser session.
The technical implementation of this vulnerability stems from inadequate input validation and output encoding within the web application's response handling mechanisms. When a victim user accesses the compromised module through their browser, the malicious script embedded in the crafted URL gets executed in the context of the vulnerable web application, potentially allowing the attacker to perform actions on behalf of the authenticated user. This reflected XSS vulnerability operates by manipulating the application's response to user-supplied input without proper sanitization, enabling the execution of arbitrary JavaScript code within the victim's browser.
The operational impact of this vulnerability extends beyond simple script execution, as it provides authenticated attackers with the capability to leverage the victim's privileges for unauthorized actions. Attackers could potentially access sensitive user data, modify access permissions, or perform administrative functions within the identity governance framework. The vulnerability's exploitation requires the victim to click on a maliciously crafted URL, making it particularly dangerous in social engineering scenarios where users might be tricked into accessing compromised links. This vector of attack aligns with common exploitation techniques documented in the attack pattern taxonomy under the MITRE ATT&CK framework for web application attacks.
The security implications of this vulnerability are particularly severe given the privileged nature of the RSA Identity Governance and Lifecycle platform, which manages critical access control and identity management functions. Organizations relying on these products face potential unauthorized access to sensitive identity data and privileged operations. The vulnerability's classification under CWE-79 - Improper Neutralization of Input During Web Page Generation in a Web Application indicates the fundamental flaw in input sanitization processes. Security professionals should consider implementing comprehensive input validation measures, output encoding, and regular security assessments to prevent exploitation of such vulnerabilities. Organizations should immediately upgrade to the patched version 7.1.1 P03 to mitigate this risk, as the vulnerability can be exploited by malicious users with legitimate access to the system, making it a particularly concerning weakness in privileged environments.
