The vulnerability identified as CVE-2024-25300 represents a critical cross-site scripting flaw within Redaxo version 5.15.1, specifically affecting the template management functionality. This issue resides in the Name parameter handling within the Template section of the content management system, creating an avenue for malicious actors to inject persistent script code that executes in the context of other users' browsers. The vulnerability stems from insufficient input validation and output sanitization mechanisms that fail to properly escape or filter user-supplied data before rendering it within the web interface. This particular weakness allows attackers to craft malicious payloads that can be stored and subsequently executed whenever legitimate users access the affected template entries, making it a persistent threat within the application's administrative environment.
The technical exploitation of this vulnerability follows a standard XSS attack pattern where an attacker manipulates the Name parameter through the template creation or modification interface. When the crafted payload is submitted and stored within the database, it becomes part of the template metadata that gets rendered in subsequent administrative views. The vulnerability's impact extends beyond simple script execution as it can be leveraged to steal session cookies, redirect users to malicious sites, or even perform administrative actions on behalf of authenticated users. This type of vulnerability maps directly to CWE-79 - Improper Neutralization of Input During Web Page Generation, which specifically addresses the failure to properly sanitize user input before incorporating it into dynamically generated web content. The flaw also aligns with ATT&CK technique T1566.001 - Phishing via Social Media, as attackers can use this vulnerability to deliver malicious payloads through compromised administrative interfaces.
The operational impact of CVE-2024-25300 is significant for organizations utilizing Redaxo v5.15.1, as successful exploitation can lead to complete administrative compromise of the content management system. Attackers who gain access through this vulnerability can potentially modify website content, steal sensitive information, create backdoor accounts, or exfiltrate data from the system. The persistent nature of the XSS flaw means that once an attacker successfully injects malicious code, it will continue to execute against any user who views the affected templates, creating a long-term threat vector. This vulnerability particularly affects organizations that rely on Redaxo for their web presence, as the administrative interface becomes a prime target for attackers seeking to establish persistent access to their digital infrastructure. The vulnerability's classification as a server-side XSS issue means that it affects all users who have access to the administrative template management functionality, potentially compromising the entire web application ecosystem.
Mitigation strategies for CVE-2024-25300 must focus on immediate patching of the Redaxo application to the latest stable version that addresses this specific vulnerability. Organizations should implement comprehensive input validation and output encoding mechanisms throughout the application, particularly in all user-facing parameters including the Name field within template sections. The implementation of Content Security Policy headers can provide additional defense-in-depth measures to prevent script execution, while regular security audits of input handling routines should be conducted to identify similar vulnerabilities. Organizations should also consider implementing web application firewalls that can detect and block malicious payload patterns associated with XSS attacks. Additionally, privileged access controls should be enforced to limit the scope of potential damage, ensuring that only authorized personnel have access to template management functionalities. The remediation process should include thorough testing of the patched version to ensure that the XSS vulnerability is completely resolved without introducing regressions in the application's core functionality.
