What it detects
This rule detects unauthenticated HTTP POST requests to the Confluence setup-restore endpoints used to exploit the improper authorization vulnerability CVE-2023-22518. It is associated with attacks against Atlassian Confluence Data Center and Server that abuse the restore functionality to import a malicious ZIP. Successful exploitation lets an attacker reset the instance and create administrative access, so this activity should be triaged as a potential compromise.
