CVE-2024-11319
Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') (CWE-79)
Summary
An Improper Neutralization of Input During Web Page Generation (XSS or 'Cross-site Scripting') vulnerability has been identified in django CMS Association's django-cms. This vulnerability allows for Cross-Site Scripting (XSS) attacks. The affected versions of django-cms are 3.11.7, 3.11.8, 4.1.2, and 4.1.3.
Impact
This vulnerability could allow an attacker to execute malicious scripts in a user's browser within the context of the affected django-cms site. The potential impacts include: 1. Theft of sensitive data: Attackers could steal session tokens, cookies, or other critical information stored in the browser. 2. Account takeover: The vulnerability could be exploited to impersonate users and perform actions on their behalf. 3. Defacement: Malicious scripts could modify the appearance of web pages, potentially damaging the organization's reputation. 4. Malware distribution: Attackers could inject scripts that redirect users to malicious sites or download malware. The CVSS v4.0 base score for this vulnerability is 9.3 (Critical), indicating a severe risk. The attack vector is Adjacent, meaning the attacker needs to be on an adjacent network, but the attack complexity is Low, and no user interaction is required. Despite requiring high privileges, the potential impact on confidentiality, integrity, and availability of both the vulnerable and subsequent systems is rated as High.
Exploitation
There is no evidence that a public proof-of-concept exists. There is no evidence of proof of exploitation at the moment.
Patch
As of the provided information, there is no mention of an available patch. However, given the critical nature of the vulnerability, it is likely that the django CMS Association is working on a fix. Security teams should monitor the official django-cms repository or announcements for patch information.
Mitigation
While waiting for an official patch, consider the following mitigation strategies: 1. Upgrade: If possible, upgrade to a version of django-cms that is not affected by this vulnerability. However, as the latest versions (3.11.8 and 4.1.3) are impacted, this may not be immediately possible. 2. Input Validation: Implement strict input validation and sanitization for all user inputs, especially those that could be rendered in web pages. 3. Content Security Policy (CSP): Implement a strong Content Security Policy to mitigate the risk of XSS attacks. 4. Web Application Firewall (WAF): Deploy or configure a WAF to filter out potential XSS attacks. 5. Output Encoding: Ensure all dynamic content is properly encoded before being rendered in web pages. 6. Least Privilege: Review and restrict user privileges where possible to minimize the impact of successful attacks. 7. Regular Security Audits: Conduct thorough code reviews and security audits to identify and address similar vulnerabilities. 8. Monitor for Updates: Closely follow django-cms security announcements and apply patches as soon as they become available. Given the critical CVSS score and the widespread use of django-cms, addressing this vulnerability should be considered a high priority for security teams.
