{"id":"GHSA-8xhv-gqm4-3w99","aliases":[],"url":"https://o3.security/vulnerability/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)","published":"2024-06-07T22:26:25Z","modified":"2024-12-04T05:41:20.457754Z","cvss":{"score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Packagist","name":"zendframework/zendframework1","fixedVersion":"1.12.18"}],"fix":null,"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"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2024-12-04T05:41:20.457754Z"}}
