Summary

Masa CMS versions 7.2.8 and below, 7.3.1-7.3.13, 7.4.0-alpha.1-7.4.8, and 7.5.0-7.5.1 are vulnerable to XSS when an unsanitized ajax URL query parameter is included in the <head> section, allowing arbitrary script execution, potentially leading to session hijacking, data theft, defacement, and malware distribution. Fixed in 7.5.2, 7.4.9, 7.3.14, and 7.2.9.

Risk Assessment

The risk includes session hijacking, data theft, defacement, and malware distribution, which could lead to security breaches and reputational damage.

Recommendation

Update Masa CMS to version 7.5.2, 7.4.9, 7.3.14, or 7.2.9 and configure a WAF (e.g., ModSecurity) to block requests with common XSS payload characters in the ajax parameter.

Original NVD description (English source)

Masa CMS is an open source Enterprise Content Management platform. Versions 7.2.8 and below, 7.3.1 through 7.3.13, 7.4.0-alpha.1 through 7.4.8 and 7.5.0 through 7.5.1 are vulnerable to XSS when an unsanitized value of the ajax URL query parameter is directly included within the <head> section of the HTML page. An attacker can execute arbitrary scripts in the context of the user's session, potentially leading to Session Hijacking, Data Theft, Defacement and Malware Distribution. This issue is fixed in versions 7.5.2, 7.4.9, 7.3.14, and 7.2.9. To work around this issue, configure a Web Application Firewall (WAF) rule (e.g., ModSecurity) to block requests containing common XSS payload characters in the ajax query parameter. Alternatively, implement server-side sanitization using middleware to strip or escape dangerous characters from the ajax parameter before it reaches the vulnerable rendering logic.
