Short explanation
A missing authorization vulnerability (CWE-862) in EnterpriseDB WarehousePG allows low-privileged authenticated users to abuse built-in cluster expansion functions to block cluster-wide catalog changes and disrupt database sessions.
This security flaw enables authenticated low-privileged users to disrupt critical operations and interrupt session continuity for all users, including superusers, potentially causing severe service degradation.
What should be done?
- Follow vendor advisories and updates
- Review database roles and permissions
- Monitor sessions for deadlocks and unresponsiveness
Chain of evidence and sources
EnterpriseDB WarehousePG sürümleri 6.27.1 ile 6.27.6 ve 7.2.1 ile 7.6.0 arasında eksik yetkilendirme açığı bulunmaktadır.
Düşük yetkili bir kullanıcı gp_expand_lock_catalog() fonksiyonunu kullanarak tüm küme genelinde katalog değişikliklerini engelleyebilir.
gp_expand_bump_version() fonksiyonunun tekrar eden çağrıları, geçici tablo tutan oturumların bağlantısını keser.
Show the technical text from the sources
WarehousePG (WHPG) 6.27.1 through 6.27.6 and 7.2.1 through 7.6.0 are affected by a missing authorization vulnerability (CWE-862) in the built-in cluster expansion functions gp_expand_lock_catalog() and gp_expand_bump_version(). Any authenticated database role can run them, and neither checks privileges. A low-privileged user can call gp_expand_lock_catalog() inside an open transaction to block all catalog changes across the cluster for every user, superusers included, until that transaction ends, which in practice requires a superuser to terminate the session. Blocked changes include DDL, temporary table creation, GRANT and CREATE ROLE. The same user can call gp_expand_bump_version() repeatedly. Each call disconnects sessions that hold temporary tables, with a FATAL error on their next catalog change, and makes every other session rebuild its segment connections.
