Users are recommended to upgrade to version 24.09.08, which fixes this issue.","cvssScore":8.8,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","cwes":["CWE-1336"],"vendors":[],"products":[],"references":[{"url":"https://lists.apache.org/thread.html/7b2syzksp7klt9fvhdg0olldvs2g83lz","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":{"summary":"Server-Side Template Injection (CWE-1336) in Apache OFBiz's MacroScreenRenderer allows authenticated attackers with minimal permissions to inject FreeMarker expressions via link parameters, leading to unsandboxed Groovy code execution and full system compromise.","exploitability":"Exploitation requires only low-privilege authentication (e.g., the shipped order-entry clerk role) and a single GET request; no additional privileges or user interaction are needed.","blast_radius":"Successful exploitation grants the attacker the same OS-level privileges as the OFBiz service account, enabling full system compromise including data exfiltration, lateral movement, and persistence.","remediation":"Upgrade to Apache OFBiz version 24.09.08 or later, which contains the official fix for this issue.","detection":"No reliable host or network indicator is derivable from the published description.","tags":["ssti","rce","template-injection","webapp","ofbiz"],"model":"garnet-coder","analyzedAt":"2026-11-06T09:52:52.332Z"}}
