Severity:
CVSS 4.0: 4.8 (medium)
CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:P/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N
Affected versions:
- Apache YuniKorn before 1.10.0
Description:
Apache YuniKorn 1.9.0 and earlier allows bypassing the check for the user
annotation by setting a secondary label on the pod. If the pod has the label
'app=yunikorn' the checks limiting the user annotation content are not run. The
label is used to identify the YuniKorn application itself in the deployments.
The bypass allows any user to specify an arbitrary user info annotation. The
arbitrary user information could allow access to a queue that the user normally
would not have access to. Quota usage for the queue might be impacted if the
application runs in the incorrect queue. User based quota enforcement is also
based on the user annotation. User quota tracking could be side stepped even if
the application runs in the correct queue.
Users are recommended to upgrade to version 1.10.0, which fixes this issue.
This issue is being tracked as YUNIKORN-3472
