## What is CVE-2024-2338?

CVE-2024-2338 is a high-severity SQL injection vulnerability in DALIBO PostgreSQL Anonymizer, published on 8 Mar 2024. An attacker needs administrator access to exploit it, with no action from the victim.

### Official description

PostgreSQL Anonymizer v1.2 contains a SQL injection vulnerability that allows a user who owns a table to elevate to superuser when dynamic masking is enabled. PostgreSQL Anonymizer enables users to set security labels on tables to mask specified columns. There is a flaw that allows complex expressions to be provided as a value. This expression is then later used as it to create the masked views leading to SQL Injection. If dynamic masking is enabled, this will lead to privilege escalation to superuser after the label is created. Users that don't own a table, especially masked users cannot exploit this vulnerability. The problem is resolved in v1.3.

Weakness: CWE-89 (Improper Neutralization of Special Elements used in an SQL Command)
