CVE-2024-47533: Cobbler

Critical severity, CVSS 9.8. EPSS: 4% chance of exploitation in the next 30 days.

Cobbler, a Linux installation server that allows for rapid setup of network installation environments, has an improper authentication vulnerability starting in version 3.0.0 and prior to versions 3.2.3 and 3.3.7. `utils.get_shared_secret()` always returns `-1`, which allows anyone to connect to cobbler XML-RPC as user `''` password `-1` and make any changes. This gives anyone with network access to a cobbler server full control of the server. Versions 3.2.3 and 3.3.7 fix the issue.

Affected products

• Cobbler Cobbler: from 3.0.0, before 3.2.3 (fixed in 3.2.3); from 3.3.0, before 3.3.7 (fixed in 3.3.7)
• Cobbler Project Cobbler: from 3.0.0, before 3.2.3 (fixed in 3.2.3); from 3.3.0, before 3.3.7 (fixed in 3.3.7)
