Overview
CVE-2024-32643 describes a high-severity vulnerability in Masa CMS, an open-source Enterprise Content Management platform. This vulnerability allows unauthorized users to bypass group restrictions and access restricted content by manipulating the URL to include a /tag/ declaration. Successful exploitation could lead to unauthorized access to sensitive information and potentially compromise the integrity of the CMS.
This vulnerability affects Masa CMS versions prior to 7.2.8, 7.3.13, and 7.4.6. It has been addressed in versions 7.2.8, 7.3.13, and 7.4.6.
Technical Details
The vulnerability stems from insufficient input validation and access control mechanisms when handling URLs containing the /tag/ declaration. By appending /tag/ to a page’s URL, the CMS incorrectly renders the page, effectively ignoring configured group restrictions intended to limit access to specific content. This means that users who would normally be denied access based on their group membership can view content they are not authorized to see.
CVSS Analysis
The Common Vulnerability Scoring System (CVSS) score for CVE-2024-32643 is 7.5 (HIGH).
- CVSS Vector: Awaiting Official Vector
- Impact: Allows unauthorized information disclosure due to bypassed access controls.
Possible Impact
Exploitation of CVE-2024-32643 can have significant consequences:
- Unauthorized Access to Sensitive Information: Attackers can access restricted content, including confidential data, internal documents, and proprietary information.
- Data Breach: Exposure of sensitive data can lead to data breaches, potentially resulting in legal and reputational damage.
- Compromised Content Integrity: Although the vulnerability is primarily for information disclosure, access to restricted pages may indirectly facilitate content manipulation or unauthorized modifications, depending on the CMS configuration and attacker capabilities.
Mitigation or Patch Steps
The most effective way to mitigate CVE-2024-32643 is to upgrade your Masa CMS installation to one of the following versions:
- Version 7.2.8 or later
- Version 7.3.13 or later
- Version 7.4.6 or later
If upgrading is not immediately feasible, consider implementing temporary workarounds, such as:
- Implementing URL rewriting rules to block requests containing the “/tag/” pattern.
- Reviewing and hardening access control configurations to ensure proper group restrictions are in place and functioning correctly.
Important: These workarounds are temporary measures and should not be considered a substitute for upgrading to a patched version.
