CVE-2024-7348

  1. OpenCVE
  2. Vulnerabilities (CVE)
  3. CVE-2024-7348
Time-of-check Time-of-use (TOCTOU) race condition in pg_dump in PostgreSQL allows an object creator to execute arbitrary SQL functions as the user running pg_dump, which is often a superuser. The attack involves replacing another relation type with a view or foreign table. The attack requires waiting for pg_dump to start, but winning the race condition is trivial if the attacker retains an open transaction. Versions before PostgreSQL 16.4, 15.8, 14.13, 13.16, and 12.20 are affected.

Summary
  • (es) La condición de ejecución de tiempo de verificación de tiempo de uso (TOCTOU) en pg_dump en PostgreSQL permite a un creador de objetos ejecutar funciones SQL arbitrarias como el usuario que ejecuta pg_dump, que a menudo es un superusuario. El ataque implica reemplazar otro tipo de relación con una vista o tabla externa. El ataque requiere esperar a que se inicie pg_dump, pero ganar la condición de ejecución es trivial si el atacante retiene una transacción abierta. Las versiones anteriores a PostgreSQL 16.4, 15.8, 14.13, 13.16 y 12.20 se ven afectadas.
