Attack Background

Object-Graph Navigation Language (OGNL) is an expression language for setting Java object properties in web applications. Atlassian Confluence has an OGNL injection vulnerability that enables attackers to run arbitrary code on the server. An attacker sends an HTTP request with injected, URL-encoded OGNL fragments to the Confluence server. These fragments include a malicious command. The server processes the OGNL fragments, running the malicious command. Command output is sent to the attacker in an HTTP response from the server.

Mitigation Options

Upgrade to Confluence Server and Data Center 7.4.17, 7.13.7, 7.14.3, 7.15.2, 7.16.4, 7.17.4 or 7.18.1
