CVE-2023-33243

Exp

RedTeam Pentesting discovered that the web interface of STARFACE as well as its REST API allows authentication using the SHA512 hash of the password instead of the cleartext password. While storing password hashes instead of cleartext passwords in an application's database generally has become best practice to protect users' passwords in case of a database compromise, this is rendered ineffective when allowing to authenticate using the password hash.

Attack vector (AV:N)
Could be attacked over the internet or any normal routed network—not just someone sitting at the machine.
Attack complexity (AC:H)
Even with access, the exploit needs extra luck, timing, or a fussy environment to actually work.
Privileges required (PR:N)
No account or special rights needed—anonymous or random user is enough.
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:H)
Could take the service down hard or make it unusable for people who depend on it.
