CVE-2023-38335: Omnis Studio 10.22.00 has incorrect access control

This week

MEDIUM 5.3REMOTEDOWNGRADE

CVE-2023-38335 is a medium-severity flaw (CVSS 5.3) affecting studio. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

Omnis Studio 10.22.00 has incorrect access control. It advertises a feature for making Omnis libraries "always private" - this is supposed to be an irreversible operation. However, due to implementation issues, "always private" Omnis libraries can be opened by the Omnis Studio browser by bypassing specific checks. This violates the expected behavior of an "irreversible operation".
