Technical details

A local unprivileged attacker with cross-user process inspection capabilities can read RHSM authentication tokens passed as command-line arguments to background helper processes during image retrieval operations. The vulnerability is due to improper handling of sensitive credentials in process invocation (CWE-214). An attacker gains unauthorized access to RHSM services within the compromised token's validity window.
