Vulnerability Summary: CVE-2024-11623
Overview
The vulnerability identified as CVE-2024-11623 was publicly disclosed on February 4, 2025, by the software provider goauthentik. It affects the Authentik product, specifically all versions released before 2024.10.4. The vulnerability type is classified under the Common Weakness Enumeration (CWE) as CWE-79, which pertains to inadequate neutralization of input during web page generation, leading to Cross-Site Scripting (XSS) vulnerabilities.
Vulnerability Details
Reported to CERT Polska, the vulnerability allows for stored XSS attacks via specially crafted SVG file uploads that are utilized as application icons within the Authentik system. This means that an authenticated attacker with administrative privileges can upload a malicious SVG file. When other users within the environment subsequently click a link referencing the affected icon, the embedded script within the SVG executes in their browsers, thereby compromising their session and potentially leading to further exploitation.
This vulnerability poses a significant risk as it can be leveraged to execute arbitrary scripts in the context of an affected user’s session, allowing attackers to hijack accounts, steal sensitive data, or perform unauthorized actions. It is essential to note that the problem was effectively mitigated with the release of version 2024.10.4 of the product.
Mitigation and Remediation
To protect against this vulnerability, users are advised to upgrade to version 2024.10.4 or later as soon as possible. By archiving and properly maintaining a strict updating policy, organizations can prevent potential exploitation of this and other vulnerabilities. Additionally, implementing web application firewalls and proper input validation measures can help mitigate the risk of similar vulnerabilities in the future.
