Summary
An issue was discovered in Sonatype Nexus Repository Manager in versions 3.21.1 and 3.22.0. It is possible for a user with appropriate privileges to create, modify, and execute scripting tasks without use of the UI or API. NOTE: in 3.22.0, scripting is disabled by default (making this not exploitable).
Risk Assessment
The risk is the possibility of unauthorized script execution by privileged users, which could lead to uncontrolled system changes or privilege escalation.
Recommendation
Update Sonatype Nexus Repository Manager to a version later than 3.22.0 and ensure scripting is disabled by default if possible.
