{"id":"GHSA-f4fj-q6m4-cc52","aliases":[],"title":"ZendFramework vulnerable to XXE/XEE attacks","titleSource":"OSV","descriptionSource":"OSV","declaredSeverity":"CRITICAL","description":"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.","severity":"critical","score":9.8,"published":"2024-06-07T21:10:24.000Z","modified":"2024-12-04T05:38:49.963Z","withdrawn":false,"knownExploited":false,"affected":[{"ecosystem":"Packagist","name":"zendframework/zend-xmlrpc","sources":[{"name":"OSV · GHSA-f4fj-q6m4-cc52","url":"https://osv.dev/vulnerability/GHSA-f4fj-q6m4-cc52"}],"ranges":[{"events":[{"introduced":"2.1.0"},{"fixed":"2.1.6"}],"type":"ECOSYSTEM"}],"versions":["2.1.0","2.1.1","2.1.2","2.1.3","2.1.4","2.1.5"],"fixed":["2.1.6"]},{"ecosystem":"Packagist","name":"zendframework/zend-xmlrpc","sources":[{"name":"OSV · GHSA-f4fj-q6m4-cc52","url":"https://osv.dev/vulnerability/GHSA-f4fj-q6m4-cc52"}],"ranges":[{"events":[{"introduced":"2.2.0"},{"fixed":"2.2.6"}],"type":"ECOSYSTEM"}],"versions":["2.2.0","2.2.1","2.2.2","2.2.3","2.2.4","2.2.5"],"fixed":["2.2.6"]}],"sourceAffected":[],"references":["https://github.com/zendframework/zend-xmlrpc/commit/0ee07bc62e32ddde2680a48fe13fd58c28a208aa","https://github.com/zendframework/zend-xmlrpc/commit/204ccbee883487e4873bce89278c48e370c21a63","https://github.com/zendframework/zend-xmlrpc/commit/27201f2c48acb3ab6135e8772211d9cb707693d6","https://github.com/zendframework/zend-xmlrpc/commit/48f20929f93df4a79254c85155aaebbbe330dc93","https://github.com/zendframework/zend-xmlrpc/commit/7a42486b63797a37af5c26be1bd3d4fb235a5939","https://github.com/zendframework/zend-xmlrpc/commit/93376258630eab4823cd5009a7230e17073feed8","https://framework.zend.com/security/advisory/ZF2014-01","https://github.com/FriendsOfPHP/security-advisories/blob/master/zendframework/zend-xmlrpc/ZF2014-01.yaml","https://github.com/zendframework/zend-xmlrpc"],"sources":[{"name":"OSV","id":"GHSA-f4fj-q6m4-cc52","modified":"2024-12-04T05:38:49.963691Z","url":"https://osv.dev/vulnerability/GHSA-f4fj-q6m4-cc52"}],"assessments":[{"source":"OSV","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8}],"products":[],"remediation":[],"kev":{"status":"unavailable","checkedAt":"2026-10-28T10:55:32.941Z"},"coverage":[{"source":"NVD","status":"not-checked"},{"source":"GHSA","status":"not-checked"},{"source":"EUVD","status":"not-checked"},{"source":"EPSS","status":"not-checked"}],"evidence":[]}
