CVE-2023-46138 | JumpServer default admin user email leak password reset

JumpServer is an open source bastion host and maintenance security audit system that complies with 4A specifications. Prior to version 3.8.0, the default email for initial user admin is `admin[@]mycompany[.]com`, and users reset their passwords by sending an email. Currently, the domain `mycompany.com` has not been registered. However, if it is registered in the future, it may affect the password reset functionality. This issue has been patched in version 3.8.0 by changing the default email domain to `example.com`. Those who cannot upgrade may change the default email domain to `example.com` manually.

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:N)
Doesn’t really leak secrets in a meaningful way.
Integrity (I:N)
Data isn’t meaningfully altered or forged.
Availability (A:L)
Might cause slowdowns, glitches, or partial disruption—not a full brick.
