**Name of the Vulnerable Software and Affected Versions** The product name cannot be determined (affected versions not specified) **Description** An authenticated, low-privileged backend user can exploit a backend AJAX endpoint used for inline editing that fails to restrict access to fields the user is not permitted to see or edit. By supplying arbitrary table, field, and record parameters, an attacker can trigger an error response that discloses the current database value of the requested field. This can lead to the exposure of sensitive information, including password hashes for both backend and frontend users. Exploitation requires a valid account with access to the extensions backend module. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.

**Name of the Vulnerable Software and Affected Versions** Mask extension (affected versions not specified) **Description** An authenticated backend user with access to the Mask module can perform path traversal, a technique used to access files and directories that are restricted from the user. The extension fails to validate a client-supplied template element key used to build file paths for saving and deleting Mask template files. By supplying a key containing path traversal sequences, an attacker can create or delete .html files outside the configured template directory. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.

**Name of the Vulnerable Software and Affected Versions** News system (news) (affected versions not specified) **Description** The extension fails to properly sanitize user input before using it in a database query. This allows an unauthenticated attacker to perform SQL injection, which is the insertion of malicious SQL code into a query, through a URL parameter on pages utilizing the "Date Menu of news articles" plugin. This issue is exploitable when the "Date Menu of news articles" plugin is active and the TypoScript/Plugin setting `disableOverrideDemand` is not enabled. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability. Enable the TypoScript/Plugin setting `disableOverrideDemand` to mitigate the risk of exploitation.

**Name of the Vulnerable Software and Affected Versions** TYPO3 versions prior to 8.7.57 ELTS TYPO3 versions prior to 9.5.46 ELTS TYPO3 versions prior to 10.4.43 ELTS TYPO3 versions prior to 11.5.35 LTS TYPO3 versions prior to 12.4.11 LTS TYPO3 versions prior to 13.0.1 **Description** The issue concerns password hashes being reflected in the editing forms of the TYPO3 backend user interface, allowing attackers to crack the plaintext password using brute force techniques. Exploiting this issue requires a valid backend user account. **Recommendations** Update to TYPO3 version 8.7.57 ELTS or later Update to TYPO3 version 9.5.46 ELTS or later Update to TYPO3 version 10.4.43 ELTS or later Update to TYPO3 version 11.5.35 LTS or later Update to TYPO3 version 12.4.11 LTS or later Update to TYPO3 version 13.0.1 or later
