    Field note · TruePositive EditorialCurated

    An unauthenticated attacker can run code on Confluence Server or Data Center by putting an OGNL expression into a crafted URL. It was exploited as a zero-day and then became a common commodity attack, and internet-facing Confluence is a repeat entry point for ransomware.

    Who is affected: Confluence Server and Data Center on vulnerable versions. Confluence Cloud is not affected.

    Very important: because this was a zero-day, if your Confluence was internet-facing and unpatched in mid-2022, assume it may have been reached and investigate.

    Commonly flagged by: Nessus, Qualys, Rapid7.

    Remediation · TruePositive EditorialCurated

    Patch to a fixed Confluence version. If it was exposed before you patched, run incident response and look for web shells and for unexpected child processes spawned by the Confluence Java process. Put Confluence behind SSO or a VPN so it is not directly open to the internet.
