{"id":"CVE-2026-102427","published":"2026-09-30T16:17:06.623","lastModified":"2026-10-01T13:46:23.090","description":"Joomla Extension - ordasoft.com - Unauthenticated Remote Code Execution in OrdaSoft Joomla CCK < 8.3.16 - site/uploader.php is reached through the component’s normal frontend routing (task=getContent), a task with no authentication or ACL check anywhere in the dispatch chain. The handler validates the uploaded file’s content with a real magic-byte MIME check, but the extension allow-list that would otherwise restrict the saved file’s extension was present in the source and commented out. The saved file’s extension was taken directly from the attacker-supplied filename with no validation, and the file was written to a path directly under the Joomla web root that is executed by the PHP handler. An image/PHP polyglot, a file whose header bytes satisfy the MIME check with PHP source appended after, passed the content check while carrying a .php extension of the attacker’s choosing.","cvssScore":10,"cvssSeverity":"CRITICAL","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H","cwes":["CWE-434"],"vendors":["ordasoft"],"products":["joomla cck"],"references":[{"url":"https://www.ordasoft.com/","tags":["Product"]}],"exploitRefs":[],"hasPoc":false,"ai":{"summary":"This vulnerability allows unauthenticated attackers to execute arbitrary code on the server by uploading a specially crafted image file with PHP code embedded in the filename and header, leading to remote code execution.","exploitability":"Exploitation is relatively easy as the vulnerability requires no authentication and the attacker can upload a file through the frontend routing of the component.","blast_radius":"If exploited, this could result in complete compromise of the server, including data theft, unauthorized access, and potential propagation of the attack to other systems.","remediation":"Upgrade to OrdaSoft Joomla CCK version 8.3.16 or later.","detection":"No reliable host or network indicator is derivable from the published description.","tags":["rce","web","unauth","php"],"model":"qwen2.5:7b-instruct","analyzedAt":"2026-10-02T08:41:23.533Z"}}
