Potential access control security issue in apollo-adminservice

CVE-2020-15170 → View on GitHub ↗ View on CVE.org ↗ View on NVD ↗

Description

Impact

If users expose apollo-adminservice to internet(which is not recommended), there are potential security issues since apollo-adminservice is designed to work in intranet and it doesn't have built-in access control. Malicious hackers may access apollo-adminservice apis directly to access/edit the application's configurations.

Patches

Access control for admin service was added in #3233 and was released in v1.7.1.

Workarounds

To fix the potential issue without upgrading, simply follow the advice that do not expose apollo-adminservice to internet.

CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:H/A:L Click to expand
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:L)
Some sensitive info could get out, but not a total data dump.
Integrity (I:H)
They could widely tamper with or forge data—trust in the data is badly hurt.
Availability (A:L)
Might cause slowdowns, glitches, or partial disruption—not a full brick.
