CVE-2025-47937: CWE-863: Incorrect Authorization in TYPO3 typo3
TYPO3 is an open source, PHP based web content management system. Starting in version 9.0.0 and prior to versions 9.5.51 ELTS, 10.4.50 ELTS, 11.5.44 ELTS, 12.4.31 LTS, and 13.4.12 LTS, when performing a database query involving multiple tables through the database abstraction layer (DBAL), frontend user permissions are only applied via `FrontendGroupRestriction` to the first table. As a result, data from additional tables included in the same query may be unintentionally exposed to unauthorized users. Users should update to TYPO3 version 9.5.51 ELTS, 10.4.50 ELTS, 11.5.44 ELTS, 12.4.31 LTS, or 13.4.12 LTS to fix the problem.
AI Analysis
Technical Summary
CVE-2025-47937 is a security vulnerability identified in TYPO3, an open-source PHP-based web content management system widely used for building and managing websites. The vulnerability arises from an incorrect authorization implementation in TYPO3's database abstraction layer (DBAL) when executing queries involving multiple tables. Specifically, frontend user permissions are enforced only on the first table in a multi-table query via the FrontendGroupRestriction mechanism. This flawed authorization logic allows unauthorized users to access data from additional tables included in the same query, potentially exposing sensitive information that should be restricted. The issue affects TYPO3 versions starting from 9.0.0 up to but not including the patched versions 9.5.51 ELTS, 10.4.50 ELTS, 11.5.44 ELTS, 12.4.31 LTS, and 13.4.12 LTS. The vulnerability is categorized under CWE-863 (Incorrect Authorization), indicating a failure to properly restrict access to resources. The CVSS v3.1 base score is 3.7, reflecting a low severity level, with the vector indicating network attack vector, high attack complexity, no privileges required, no user interaction, unchanged scope, and limited confidentiality impact. No known exploits are currently reported in the wild. The vulnerability could lead to unauthorized disclosure of data from secondary tables in database queries, which may include user data or other sensitive content depending on the TYPO3 implementation and database schema. Users are advised to upgrade to the fixed TYPO3 versions to remediate this issue.
Potential Impact
For European organizations using TYPO3 as their content management system, this vulnerability poses a risk of unauthorized data exposure. While the severity is rated low, the impact depends on the nature of the data stored in the additional tables queried alongside the primary table. Potentially sensitive customer information, internal content, or configuration data could be inadvertently disclosed to unauthorized frontend users. This could lead to privacy violations under regulations such as the GDPR, resulting in legal and reputational consequences. The risk is heightened for organizations that rely heavily on TYPO3 for public-facing websites with complex database queries involving multiple tables. However, since exploitation does not require authentication or user interaction, attackers could remotely probe vulnerable TYPO3 instances to extract unauthorized data. The low CVSS score suggests limited confidentiality impact and high attack complexity, but the exposure of any sensitive data is critical in regulated environments. Therefore, European entities should consider this vulnerability seriously, especially those in sectors like government, healthcare, finance, and e-commerce where data protection is paramount.
Mitigation Recommendations
To mitigate this vulnerability, European organizations should promptly update TYPO3 installations to the patched versions: 9.5.51 ELTS, 10.4.50 ELTS, 11.5.44 ELTS, 12.4.31 LTS, or 13.4.12 LTS, depending on their current version. Beyond patching, organizations should audit their TYPO3 database queries, particularly those involving multiple tables, to verify that appropriate access controls are enforced on all queried tables. Implementing additional application-layer access controls or database-level permissions can provide defense-in-depth. Monitoring and logging database queries and frontend user activities may help detect anomalous access patterns indicative of exploitation attempts. Restricting public access to sensitive backend APIs or database query interfaces can reduce exposure. Regular security assessments and penetration testing focused on authorization logic in TYPO3 deployments are recommended. Finally, organizations should maintain an inventory of TYPO3 instances and ensure timely application of security updates as part of their vulnerability management process.
