"value": "0day Rubbish Research Team is publicly disclosing a vulnerability in Apache Struts 2 2.6.11.0 (Apache Software \nFoundation). The research is published and a proof-of-concept is available.\n\nPre-authentication RCE (CVSS 9.8, pre-authentication)\n\nApache Struts 2.6.11.0 is vulnerable to unauthenticated remote code execution under a documented REST mapper \nconfiguration combined with wildcard dynamic dispatch. RestfulActionMapper.getMapping() extracts the action name from \nthe request URI without calling cleanupActionName, the character-set gate that DefaultActionMapper adopted after \nS2-057; that fix was never synchronized to the REST mapper. When an application uses struts.mapper.class=restful with a \nwildcard action and a result containing {1} substitution, attacker-controlled OGNL metacharacters flow through the \nwildcard capture into TextParseUtil.translateVariables, bypassing AcceptedPatternsChecker. A novel \njava.beans.Expression/Statement reflection primitive then defeats the SecurityMemberAccess sandbox and reaches \nRuntime.exec. The chain was verified with uid=0(root) on a Tomcat 9 / OGNL 3.3.5 deployment. The only precondition is \nan opt-in but documented configuration subset (REST mapper plus wildcard dynamic dispatch).\n\nImpact: Arbitrary operating system command execution as the JVM process user; on a root-run deployment, full host \ncompromise. No credentials are required.\n\nAdvisory: https://0day-rubbish.com/blog/apache-struts2-restful-mapper-ognl-rce\n\nPoC and full analysis: https://github.com/Exploit-Garbage/0day-Rubbish\n\n-- \n0day Rubbish Research Team\nhttps://0day-rubbish.com\n_______________________________________________\nSent through the Full Disclosure mailing list\nhttps://nmap.org/mailman/listinfo/fulldisclosure\nWeb Archives & RSS: https://seclists.org/fulldisclosure/"
