Description
CVE-2026-3623 is a high-severity vulnerability in IBM Netezza Performance Server Replication Services versions 3.0.2.0 through 3.0.5.0. It allows an attacker with low-privileged access to escalate their privileges to root, enabling execution of root-level commands, obtaining a root shell, changing the root password, modifying or deleting system-wide files, and installing persistent backdoors. This leads to full system compromise with complete loss of confidentiality, integrity, and availability.
