{"id":"GHSA-8x2v-pcg7-94f4","aliases":[],"url":"https://o3.security/vulnerability/GHSA-8x2v-pcg7-94f4","summary":"Zend-JSON 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":"2024-06-07T21:49:11Z","modified":"2024-12-04T05:40:59.875563Z","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-json","fixedVersion":"2.1.6"},{"ecosystem":"Packagist","name":"zendframework/zend-json","fixedVersion":"2.2.6"}],"fix":{"url":"https://github.com/zendframework/zend-json/commit/078e77a6e59cdbf32a94691afe3523db340f5da9","label":"zendframework/zend-json@078e77a"},"references":[{"type":"WEB","url":"https://github.com/zendframework/zend-json/commit/078e77a6e59cdbf32a94691afe3523db340f5da9"},{"type":"WEB","url":"https://github.com/zendframework/zend-json/commit/7a747fbefe566c28a94b7e7ca37c15fc09ba4754"},{"type":"WEB","url":"https://github.com/zendframework/zend-json/commit/865f96ecbc5e080fccb5e75304ce06ac57d2ce22"},{"type":"WEB","url":"https://github.com/zendframework/zend-json/commit/89fc6f760478dc15519cb3ef4e4976425dc6ee10"},{"type":"WEB","url":"https://github.com/zendframework/zend-json/commit/9fe5103dc9be472fa0a443ca36619a2953b6f88e"},{"type":"WEB","url":"https://github.com/zendframework/zend-json/commit/acc60fc3fe56f5b0ad218c4c5789b21f11bc3a89"},{"type":"WEB","url":"https://framework.zend.com/security/advisory/ZF2014-01"},{"type":"WEB","url":"https://github.com/FriendsOfPHP/security-advisories/blob/master/zendframework/zend-json/ZF2014-01.yaml"},{"type":"PACKAGE","url":"https://github.com/zendframework/zend-json"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2024-12-04T05:40:59.875563Z"}}
