Weak password hash in LiveHelperChat

Description

The secrethash, which the application relies for multiple security measures, can be brute-forced. The hash is quite small, with only 10 characters of only hexadecimal, making 16^10 possilibities ( 1.099.511.627.776 ). The SHA1 of the secret can be obtained via a captcha string and brute-forced offline with an GPU.

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:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
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:N)
Doesn’t really leak secrets in a meaningful 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.
