{"id":"GHSA-hg35-vqp3-fv39","aliases":[],"title":"ZendFramework potential Cross-site Scripting vectors due to inconsistent encodings","description":"A number of classes, primarily within the `Zend_Form`, `Zend_Filter`, `Zend_Form`, `Zend_Log` and `Zend_View components`, contained character encoding inconsistencies whereby calls to the `htmlspecialchars()` and htmlentities() functions used undefined or hard coded charset parameters. In many of these cases developers were unable to set a character encoding of their choice. These inconsistencies could, in specific circumstances, allow certain multibyte representations of special HTML characters pass through unescaped leaving applications potentially vulnerable to cross-site scripting (XSS) exploits. Such exploits would only be possible if a developer used a non-typical character encoding (such as UTF-7), allowed users to define the character encoding, or served HTML documents without a valid character set defined.\n\n","severity":"medium","score":6.1,"published":"2024-06-07T21:14:54.000Z","modified":"2024-06-07T21:14:54.000Z","withdrawn":false,"knownExploited":false,"affected":[{"ecosystem":"Packagist","name":"zendframework/zendframework1","ranges":[{"events":[{"introduced":"1.9.0"},{"fixed":"1.9.7"}],"type":"ECOSYSTEM"}],"versions":[],"fixed":["1.9.7"]}],"references":["https://framework.zend.com/security/advisory/ZF2010-01","https://github.com/FriendsOfPHP/security-advisories/blob/master/zendframework/zendframework1/ZF2010-01.yaml","https://github.com/zendframework/zf1"],"sources":[{"name":"OSV","id":"GHSA-hg35-vqp3-fv39","modified":"2024-06-07T21:14:54Z","url":"https://osv.dev/vulnerability/GHSA-hg35-vqp3-fv39"}],"assessments":[{"source":"OSV","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","score":6.1}]}
