Overview

CVE-2024-2339 is a high-severity vulnerability. It was published on March 8, 2024 and has a CVSS 3.1 base score of 8.0 (HIGH).

This vulnerability has a CVSS 3.1 base score of 8.0, rated HIGH. It can be exploited remotely over the network. Some level of privileges is required for exploitation.

Technical description

PostgreSQL Anonymizer v1.2 contains a vulnerability that allows a user who owns a table to elevate to superuser. A user can define a masking function for a column and place malicious code in that function. When a privileged user applies the masking rules using the static masking or the anonymous dump method, the malicious code is executed and can grant escalated privileges to the malicious user. PostgreSQL Anonymizer v1.2 does provide a protection against this risk with the restrict_to_trusted_schemas option, but that protection is incomplete. Users that don't own a table, especially masked users cannot exploit this vulnerability. The problem is resolved in v1.3.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
