How the CVE Works
CVE-2025-33122 exploits an unqualified library call in IBM Advanced Job Scheduler for i (versions 7.2-7.6). Attackers can manipulate library paths to load malicious code instead of legitimate system libraries. Due to improper path validation, the scheduler executes this code with elevated administrator privileges, leading to privilege escalation. The vulnerability stems from insufficient library path sanitization, allowing attackers to hijack the execution flow.
