What it detects
This rule detects HTTP requests that re-enable the Confluence setup workflow by toggling setupComplete to false and then hitting the setup administrator and finish-setup actions, matching exploitation of the broken access control flaw CVE-2023-22515. It is associated with attacks against internet-facing Atlassian Confluence servers to create rogue administrator accounts. Because these endpoints should never be reachable on a configured instance, this pattern strongly indicates active exploitation.
