CVE-2025-54882 | Himmelblau's Kerberos credential cache collection is world readable

Exp

Himmelblau is an interoperability suite for Microsoft Azure Entra ID and Intune. In versions 0.8.0 through 0.9.21 and 1.0.0-beta through 1.1.0, Himmelblau stores the cloud TGT received during logon in the Kerberos credential cache. The created credential cache collection and received credentials are stored as world readable. This is fixed in versions 0.9.22 and 1.2.0. To work around this issue, remove all read access to Himmelblau caches for all users except for owners.

Base score Version Severity Vector Exploitability Impact Score source
7.1 3.1 HIGH
CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N Click to expand
Attack vector (AV:L)
They already need access on the box, or another person has to do something wrong; it’s not a remote drive-by.
Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:L)
A normal user session is enough; they don’t have to be admin.
User interaction (UI:N)
Nobody has to click “OK” or open a trap file; it can work without a victim helping.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:H)
Serious risk that confidential data gets exposed in a big way.
Integrity (I:H)
They could widely tamper with or forge data—trust in the data is badly hurt.
Availability (A:N)
Service keeps running; no real outage angle.
