The vulnerability identified as CVE-2024-25875 represents a critical cross-site scripting flaw within the Header module of Enhavo CMS version 0.13.1. This security weakness stems from insufficient input validation and output sanitization mechanisms that fail to properly filter malicious content submitted through the Undertitle text field. The vulnerability creates an avenue for attackers to inject arbitrary JavaScript code or HTML payloads that can be executed in the context of other users' browsers when they view affected content. Such a flaw fundamentally undermines the integrity of user sessions and can lead to unauthorized access to sensitive data or system compromise.
The technical exploitation of this vulnerability occurs through the manipulation of the Undertitle text field within the Header module, where attackers can craft malicious payloads that bypass existing security controls. The flaw resides in the application's failure to implement proper content sanitization before rendering user-supplied input, allowing attackers to inject script tags or other malicious code that executes when legitimate users browse pages containing the compromised content. This type of vulnerability falls under CWE-79 - Improper Neutralization of Input During Web Page Generation, which specifically addresses the failure to sanitize user input that gets reflected back to users in web applications. The vulnerability is particularly dangerous because it operates at the user interaction level, making it difficult to detect and mitigate without proper input validation controls.
The operational impact of CVE-2024-25875 extends beyond simple script execution, as it can enable attackers to perform session hijacking, deface websites, steal sensitive cookies, or redirect users to malicious domains. When legitimate users interact with pages containing the injected payloads, their browsers execute the malicious code in their context, potentially leading to unauthorized access to administrative functions or personal data exposure. The vulnerability's exploitation aligns with ATT&CK technique T1566.001 - Phishing: Spearphishing Attachment, as attackers can leverage this flaw to deliver malicious payloads through seemingly legitimate content management interfaces. Additionally, the vulnerability may facilitate more sophisticated attacks such as credential theft or lateral movement within compromised systems.
Organizations utilizing Enhavo CMS v0.13.1 should implement immediate mitigations including comprehensive input validation, output encoding, and the implementation of Content Security Policies to prevent script execution. The recommended approach involves sanitizing all user-supplied content before storage and applying proper HTML escaping when rendering content in web pages. Security measures should also include regular security audits, input field validation, and monitoring for anomalous content submissions. The vulnerability demonstrates the critical importance of implementing defense-in-depth strategies, as proper input sanitization and output encoding would prevent the exploitation vector entirely. Organizations should also consider implementing web application firewalls and regular security patching to address similar vulnerabilities that may exist in other components of the CMS platform.
