Description
Sonatype Nexus Repository 3 did not properly filter internal configuration keys from user-supplied task properties when creating or updating a scheduled task through the administrative UI. An account holding permission to create at least one scheduled task type could supply a crafted property value that caused the system to overwrite the configuration of an unrelated, existing task instead of creating a new one.
