{"id":"GHSA-mhpx-3rv8-wrjm","summary":"ZendFramework potential XML eXternal Entity injection vectors","details":"Numerous components utilizing PHP's `DOMDocument`, `SimpleXML`, and `xml_parse` functionality are vulnerable to two types of attacks:\n\n- XML eXternal Entity (XXE) Injection attacks. The above mentioned extensions are insecure by default, allowing external entities to be specified by adding a specific DOCTYPE element to XML documents and strings. By exploiting this vulnerability an application may be coerced to open arbitrary files and/or TCP connections.\n- XML Entity Expansion (XEE) vectors, leading to Denial of Service vectors. XEE attacks occur when the XML DOCTYPE declaration includes XML entity definitions that contain either recursive or circular references; this leads to CPU and memory consumption, making Denial of Service exploits trivial to implement.\n","modified":"2024-12-04T05:32:07.571126Z","published":"2024-06-07T21:16:36Z","database_specific":{"cwe_ids":["CWE-611","CWE-776"],"severity":"CRITICAL","github_reviewed":true,"github_reviewed_at":"2024-06-07T21:16:36Z","nvd_published_at":null},"references":[{"type":"WEB","url":"https://framework.zend.com/security/advisory/ZF2014-01"},{"type":"WEB","url":"https://github.com/FriendsOfPHP/security-advisories/blob/master/zendframework/zendframework1/ZF2014-01.yaml"},{"type":"PACKAGE","url":"https://github.com/zendframework/zf1"}],"affected":[{"package":{"name":"zendframework/zendframework1","ecosystem":"Packagist","purl":"pkg:composer/zendframework/zendframework1"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"1.12.0"},{"fixed":"1.12.4"}]}],"versions":["1.12.0","1.12.1","1.12.2","1.12.3"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2024/06/GHSA-mhpx-3rv8-wrjm/GHSA-mhpx-3rv8-wrjm.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
