{"id":"GHSA-qc7w-4567-84wv","aliases":[],"url":"https://o3.security/vulnerability/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.","published":"2024-06-07T20:30:06Z","modified":"2024-12-04T05:28:49.568875Z","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/zendframework","fixedVersion":"2.1.6"},{"ecosystem":"Packagist","name":"zendframework/zendframework","fixedVersion":"2.2.6"}],"fix":{"url":"https://github.com/zendframework/zendframework/commit/225a8c9f1c3bc08c0bddf22486a8a39ff7186ac1","label":"zendframework/zendframework@225a8c9"},"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"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2024-12-04T05:28:49.568875Z"}}
