{"id":"GHSA-qc7w-4567-84wv","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.","modified":"2024-12-04T05:38:29.142825Z","published":"2024-06-07T20:30:06Z","database_specific":{"cwe_ids":["CWE-611","CWE-776"],"severity":"CRITICAL","github_reviewed":true,"github_reviewed_at":"2024-06-07T20:30:06Z","nvd_published_at":null},"references":[{"type":"WEB","url":"https://github.com/zendframework/zendframework/commit/225a8c9f1c3bc08c0bddf22486a8a39ff7186ac1"},{"type":"WEB","url":"https://github.com/zendframework/zendframework/commit/5dab7b8e77741dbba56209616b7815bb04f4c561"},{"type":"WEB","url":"https://github.com/zendframework/zendframework/commit/68d0756c596baeefad0b733b42ef2657d09c7f4e"},{"type":"WEB","url":"https://github.com/zendframework/zendframework/commit/bbcf41e676ef6d8f16ea9d6499050bca0787eb6c"},{"type":"WEB","url":"https://github.com/zendframework/zendframework/commit/ee7f81cc996fb1c16c7dae23eca9ec013ab74730"},{"type":"WEB","url":"https://github.com/zendframework/zendframework/commit/fbeba98d5a9924b026a5dd98f679143fd6be89ea"},{"type":"WEB","url":"https://framework.zend.com/security/advisory/ZF2014-01"},{"type":"WEB","url":"https://github.com/FriendsOfPHP/security-advisories/blob/master/zendframework/zendframework/ZF2014-01.yaml"},{"type":"PACKAGE","url":"https://github.com/zendframework/zendframework"}],"affected":[{"package":{"name":"zendframework/zendframework","ecosystem":"Packagist","purl":"pkg:composer/zendframework/zendframework"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.1.0"},{"fixed":"2.1.6"}]}],"versions":["2.1.0","2.1.1","2.1.2","2.1.3","2.1.4","2.1.5"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2024/06/GHSA-qc7w-4567-84wv/GHSA-qc7w-4567-84wv.json"}},{"package":{"name":"zendframework/zendframework","ecosystem":"Packagist","purl":"pkg:composer/zendframework/zendframework"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.2.0"},{"fixed":"2.2.6"}]}],"versions":["2.2.0","2.2.1","2.2.2","2.2.3","2.2.4","2.2.5"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2024/06/GHSA-qc7w-4567-84wv/GHSA-qc7w-4567-84wv.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"}]}
