{"id":"GHSA-jq4p-mq33-w375","summary":"Cross-site Scripting when rendering error messages in laminas-form","details":"### Impact\n\nWhen rendering validation error messages via the `formElementErrors()` view helper shipped with laminas-form, many messages will contain the submitted value. However, in vulnerable versions of laminas-form, the value was not being escaped for HTML contexts, which can potentially lead to a Reflected Cross-Site Scripting (XSS) attack.\n\n### Patches\n\nThe following versions were issued to mitigate the vulnerability:\n\n- 2.17.1\n- 3.0.2\n- 3.1.1\n\n### Workarounds\n\nAt the top of a view script where you call the `formElementErrors()` view helper, place the following code:\n\n```php\nuse Laminas\\Form\\ElementInterface;\nuse Laminas\\View\\PhpRenderer;\n\n$escapeMessages = function (ElementInterface $formOrElement, PhpRenderer $renderer): void {\n    $messages = $element-\u003egetMessages();\n    if (! $messages) {\n        return;\n    }\n\n    $escaped  = [];\n    array_walk_recursive(\n        $messages,\n        static function (string $item) use (&$escaped, $renderer): void {\n            $escaped[] = $renderer-\u003eescapeHtml($item);\n        }\n    };\n\n    $element-\u003esetMessages($escaped);\n};\n```\n\nBefore calling `formElementErrors()` with a form, fieldset, or element, call the above closure as follows\n\n```php\n// Usage with a form\n// $this is the view renderer\n$escapeMessages($form, $this);\n\n// Usage with a fieldset\n// $this is the view renderer\n$escapeMessages($fieldset, $this);\n\n// Usage with a form element\n// $this is the view renderer\n$escapeMessages($element, $this);\n```\n\n### For more information\n\nIf you have any questions or comments about this advisory:\n\n* [Open an issue](https://github.com/laminas/laminas-form/issues/new)\n* Email us at [security@getlaminas.org](mailto:security@getlaminas.org)","aliases":["CVE-2022-23598"],"modified":"2024-02-19T05:32:54.368200Z","published":"2022-01-28T23:08:29Z","database_specific":{"github_reviewed_at":"2022-01-28T18:49:08Z","nvd_published_at":"2022-01-28T22:15:00Z","cwe_ids":["CWE-79"],"severity":"MODERATE","github_reviewed":true},"references":[{"type":"WEB","url":"https://github.com/laminas/laminas-form/security/advisories/GHSA-jq4p-mq33-w375"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-23598"},{"type":"WEB","url":"https://github.com/laminas/laminas-form/commit/43005a3ec4c2292d4f825273768d9b884acbca37"},{"type":"WEB","url":"https://getlaminas.org/security/advisory/LP-2022-01"},{"type":"WEB","url":"https://github.com/laminas/laminas-form"},{"type":"WEB","url":"https://github.com/laminas/laminas-form/releases/tag/2.17.1"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/CFF6WJ5I7PSEBRF6I753WKE2BXFBGQXE"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/SLNABVK26CE4PFL57VLY242FW3QY4CPC"}],"affected":[{"package":{"name":"laminas/laminas-form","ecosystem":"Packagist","purl":"pkg:composer/laminas/laminas-form"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.1.0"},{"fixed":"3.1.1"}]}],"versions":["3.1.0"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2022/01/GHSA-jq4p-mq33-w375/GHSA-jq4p-mq33-w375.json"}},{"package":{"name":"laminas/laminas-form","ecosystem":"Packagist","purl":"pkg:composer/laminas/laminas-form"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.0.0"},{"fixed":"3.0.2"}]}],"versions":["3.0.0","3.0.1"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2022/01/GHSA-jq4p-mq33-w375/GHSA-jq4p-mq33-w375.json"}},{"package":{"name":"laminas/laminas-form","ecosystem":"Packagist","purl":"pkg:composer/laminas/laminas-form"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.17.1"}]}],"versions":["2.0.0","2.0.1","2.0.2","2.0.3","2.0.4","2.0.5","2.0.6","2.0.7","2.0.8","2.1.0","2.1.1","2.1.2","2.1.3","2.1.4","2.1.5","2.1.6","2.10.0","2.10.1","2.10.2","2.11.0","2.12.0","2.12.1","2.13.0","2.14.0","2.14.1","2.14.2","2.14.3","2.14.4","2.14.5","2.14.6","2.15.0","2.15.1","2.16.0","2.16.1","2.16.2","2.16.3","2.17.0","2.2.0","2.2.0rc1","2.2.0rc2","2.2.0rc3","2.2.1","2.2.10","2.2.2","2.2.3","2.2.4","2.2.5","2.2.6","2.2.7","2.2.8","2.2.9","2.3.0","2.3.1","2.3.2","2.3.3","2.3.4","2.3.5","2.3.6","2.3.7","2.3.8","2.3.9","2.4.0","2.4.0rc1","2.4.0rc2","2.4.0rc3","2.4.0rc4","2.4.0rc5","2.4.0rc6","2.4.0rc7","2.4.1","2.4.10","2.4.11","2.4.12","2.4.13","2.4.2","2.4.3","2.4.4","2.4.5","2.4.6","2.4.7","2.4.8","2.4.9","2.5.0","2.5.1","2.5.2","2.5.3","2.6.0","2.7.0","2.7.1","2.8.0","2.8.1","2.8.2","2.8.3","2.8.4","2.9.0","2.9.1","2.9.2"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2022/01/GHSA-jq4p-mq33-w375/GHSA-jq4p-mq33-w375.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N"}]}
