{"id":"GHSA-qc7w-4567-84wv","aliases":[],"title":"Zendframework vulnerable to XXE/XEE attacks","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":"2024-06-07T20:30:06.000Z","modified":"2024-12-04T05:28:49.568Z","withdrawn":false,"knownExploited":false,"affected":[{"ecosystem":"Packagist","name":"zendframework/zendframework","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/zendframework","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"]}],"references":["https://github.com/zendframework/zendframework/commit/225a8c9f1c3bc08c0bddf22486a8a39ff7186ac1","https://github.com/zendframework/zendframework/commit/5dab7b8e77741dbba56209616b7815bb04f4c561","https://github.com/zendframework/zendframework/commit/68d0756c596baeefad0b733b42ef2657d09c7f4e","https://github.com/zendframework/zendframework/commit/bbcf41e676ef6d8f16ea9d6499050bca0787eb6c","https://github.com/zendframework/zendframework/commit/ee7f81cc996fb1c16c7dae23eca9ec013ab74730","https://github.com/zendframework/zendframework/commit/fbeba98d5a9924b026a5dd98f679143fd6be89ea","https://framework.zend.com/security/advisory/ZF2014-01","https://github.com/FriendsOfPHP/security-advisories/blob/master/zendframework/zendframework/ZF2014-01.yaml","https://github.com/zendframework/zendframework"],"sources":[{"name":"OSV","id":"GHSA-qc7w-4567-84wv","modified":"2024-12-04T05:28:49.568875Z","url":"https://osv.dev/vulnerability/GHSA-qc7w-4567-84wv"}],"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}]}
