Vulnerability Title
Cockpit-machines: cockpit-machines: information disclosure of rhsm offline token via process arguments
Source: CVE Program / CVE List V5
Vulnerability Description
A flaw was found in cockpit-machines. This vulnerability allows a local attacker with the ability to inspect process metadata to disclose a sensitive Red Hat Subscription Management (RHSM) offline token. The token is exposed when it is passed as a command-line argument to a helper script during the token validation process. Successful exploitation could lead to the compromise of confidentiality, as the exposed token can be used to request access tokens.
