{"id":"GHSA-8xhv-gqm4-3w99","aliases":[],"title":"ZendFramework1 Potential Insufficient Entropy Vulnerability","description":"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)","severity":"high","score":7.5,"published":"2024-06-07T22:26:25.000Z","modified":"2024-12-04T05:41:20.457Z","withdrawn":false,"knownExploited":false,"affected":[{"ecosystem":"Packagist","name":"zendframework/zendframework1","ranges":[{"events":[{"introduced":"1.12.0"},{"fixed":"1.12.18"}],"type":"ECOSYSTEM"}],"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"],"fixed":["1.12.18"]}],"references":["https://framework.zend.com/security/advisory/ZF2016-01","https://github.com/FriendsOfPHP/security-advisories/blob/master/zendframework/zendframework1/ZF2016-01.yaml","https://github.com/zendframework/zf1"],"sources":[{"name":"OSV","id":"GHSA-8xhv-gqm4-3w99","modified":"2024-12-04T05:41:20.457754Z","url":"https://osv.dev/vulnerability/GHSA-8xhv-gqm4-3w99"}],"assessments":[{"source":"OSV","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","score":7.5}]}
