{"id":"GHSA-8xhv-gqm4-3w99","summary":"ZendFramework1 Potential Insufficient Entropy Vulnerability","details":"We discovered several methods used to generate random numbers in ZF1 that potentially used insufficient entropy. These random number generators are used in the following method calls:\n```\nZend_Ldap_Attribute::createPassword\nZend_Form_Element_Hash::_generateHash\nZend_Gdata_HttpClient::filterHttpRequest\nZend_Filter_Encrypt_Mcrypt::_srand\nZend_OpenId::randomBytes\n```\nIn each case, the methods were using rand() or mt_rand(), neither of which can generate cryptographically secure values. This could potentially lead to information disclosure should an attacker be able to brute force the random number generation.\n\nMoreover, we discovered a potential security issue in the usage of the [openssl_random_pseudo_bytes()](http://php.net/manual/en/function.openssl-random-pseudo-bytes.php) function in Zend_Crypt_Math::randBytes, reported in PHP BUG [#70014](https://bugs.php.net/bug.php?id=70014), and the security implications reported in a discussion [on the random_compat library.](https://github.com/paragonie/random_compat/issues/96)","modified":"2024-12-04T05:41:20.457754Z","published":"2024-06-07T22:26:25Z","database_specific":{"github_reviewed":true,"github_reviewed_at":"2024-06-07T22:26:25Z","nvd_published_at":null,"cwe_ids":["CWE-331"],"severity":"HIGH"},"references":[{"type":"WEB","url":"https://framework.zend.com/security/advisory/ZF2016-01"},{"type":"WEB","url":"https://github.com/FriendsOfPHP/security-advisories/blob/master/zendframework/zendframework1/ZF2016-01.yaml"},{"type":"PACKAGE","url":"https://github.com/zendframework/zf1"}],"affected":[{"package":{"name":"zendframework/zendframework1","ecosystem":"Packagist","purl":"pkg:composer/zendframework/zendframework1"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"1.12.0"},{"fixed":"1.12.18"}]}],"versions":["1.12.0","1.12.1","1.12.10","1.12.11","1.12.12","1.12.13","1.12.14","1.12.15","1.12.16","1.12.17","1.12.2","1.12.3","1.12.4","1.12.5","1.12.6","1.12.7","1.12.8","1.12.9"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2024/06/GHSA-8xhv-gqm4-3w99/GHSA-8xhv-gqm4-3w99.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:N/A:N"}]}
