{"id":"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.","modified":"2024-12-04T05:40:59.875563Z","published":"2024-06-07T21:49:11Z","database_specific":{"severity":"CRITICAL","github_reviewed":true,"github_reviewed_at":"2024-06-07T21:49:11Z","nvd_published_at":null,"cwe_ids":["CWE-611","CWE-776"]},"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"}],"affected":[{"package":{"name":"zendframework/zend-json","ecosystem":"Packagist","purl":"pkg:composer/zendframework/zend-json"},"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-8x2v-pcg7-94f4/GHSA-8x2v-pcg7-94f4.json"}},{"package":{"name":"zendframework/zend-json","ecosystem":"Packagist","purl":"pkg:composer/zendframework/zend-json"},"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-8x2v-pcg7-94f4/GHSA-8x2v-pcg7-94f4.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"}]}
