CVE-2026-3623
Vulnerabilities exists in IBM Netezza Performance Server Replication Services
Description
IBM Netezza Performance Server Replication Services 3.0.2.0 through 3.0.5.0 allows an attacker with low‑privileged access to escalate their privileges to root. By exploiting this flaw, the attacker can execute root‑level commands, obtain a root shell, and change the root user’s password. Successful exploitation also enables modification or removal of system‑wide files and the installation of persistent backdoors. This results in full system compromise with complete loss of confidentiality, integrity, and availability.
