{"id":"GHSA-f4fj-q6m4-cc52","aliases":[],"url":"https://o3.security/vulnerability/GHSA-f4fj-q6m4-cc52","summary":"ZendFramework vulnerable to XXE/XEE attacks","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.","published":"2024-06-07T21:10:24Z","modified":"2024-12-04T05:38:49.963691Z","cvss":{"score":9.8,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Packagist","name":"zendframework/zend-xmlrpc","fixedVersion":"2.1.6"},{"ecosystem":"Packagist","name":"zendframework/zend-xmlrpc","fixedVersion":"2.2.6"}],"fix":{"url":"https://github.com/zendframework/zend-xmlrpc/commit/0ee07bc62e32ddde2680a48fe13fd58c28a208aa","label":"zendframework/zend-xmlrpc@0ee07bc"},"references":[{"type":"WEB","url":"https://github.com/zendframework/zend-xmlrpc/commit/0ee07bc62e32ddde2680a48fe13fd58c28a208aa"},{"type":"WEB","url":"https://github.com/zendframework/zend-xmlrpc/commit/204ccbee883487e4873bce89278c48e370c21a63"},{"type":"WEB","url":"https://github.com/zendframework/zend-xmlrpc/commit/27201f2c48acb3ab6135e8772211d9cb707693d6"},{"type":"WEB","url":"https://github.com/zendframework/zend-xmlrpc/commit/48f20929f93df4a79254c85155aaebbbe330dc93"},{"type":"WEB","url":"https://github.com/zendframework/zend-xmlrpc/commit/7a42486b63797a37af5c26be1bd3d4fb235a5939"},{"type":"WEB","url":"https://github.com/zendframework/zend-xmlrpc/commit/93376258630eab4823cd5009a7230e17073feed8"},{"type":"WEB","url":"https://framework.zend.com/security/advisory/ZF2014-01"},{"type":"WEB","url":"https://github.com/FriendsOfPHP/security-advisories/blob/master/zendframework/zend-xmlrpc/ZF2014-01.yaml"},{"type":"PACKAGE","url":"https://github.com/zendframework/zend-xmlrpc"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2024-12-04T05:38:49.963691Z"}}
