Detailsinfo

A vulnerability classified as problematic has been found in EnterpriseDB WarehousePG up to 6.27.6/7.6.0. Affected is the function gp_add_coordinator_standby of the component Coordinator. The manipulation with an unknown input leads to a authorization vulnerability. CWE is classifying the issue as CWE-862. The product does not perform an authorization check when an actor attempts to access a resource or perform an action. This is going to have an impact on integrity, and availability. CVE summarizes:

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 gp_add_coordinator_standby(). The function is named gp_add_master_standby() in WHPG 6, and WHPG 7 keeps that name as an alias. Unlike the other segment add and remove functions, it does not require superuser privileges. A low-privileged user who can open a utility-mode connection can use it to add a fake standby coordinator entry to gp_segment_configuration on a cluster that has no standby configured. Administrators then cannot add a real standby until a superuser removes the fake entry. User data is not exposed or modified.
