{"id":"GHSA-v858-922f-fj9v","aliases":[],"title":"SimpleSAMLphp Link Injection vulnerability","titleSource":"OSV","descriptionSource":"OSV","declaredSeverity":"MODERATE","description":"### Background\nSeveral scripts part of SimpleSAMLphp display a web page with links obtained from the request parameters. This allows us to enhance usability, as the users are presented with links they can follow after completing a certain action, like logging out.\n\n### Description\nThe following scripts were not checking the URLs obtained via the HTTP request before displaying them as the target of links that the user may click on:\n\n- www/logout.php\n- modules/core/www/no_cookie.php\nThe issue allowed attackers to display links targeting a malicious website inside a trusted site running SimpleSAMLphp, due to the lack of security checks involving the link_href and retryURL HTTP parameters, respectively. The issue was resolved by including a verification of the URLs received in the request against a white list of websites specified in the trusted.url.domains configuration option.\n\n### Affected versions\nAll SimpleSAMLphp versions prior to 1.14.4.\n\n### Impact\nA remote attacker could craft a link pointing to a trusted website running SimpleSAMLphp, including a parameter pointing to a malicious website, and try to fool the victim into visiting that website by clicking on a link in the page presented by SimpleSAMLphp.\n","severity":"medium","score":5.4,"published":"2024-05-28T18:26:35.000Z","modified":"2024-12-03T06:07:22.402Z","withdrawn":false,"knownExploited":false,"affected":[{"ecosystem":"Packagist","name":"simplesamlphp/simplesamlphp","sources":[{"name":"OSV · GHSA-v858-922f-fj9v","url":"https://osv.dev/vulnerability/GHSA-v858-922f-fj9v"}],"ranges":[{"events":[{"introduced":"0"},{"fixed":"1.14.4"}],"type":"ECOSYSTEM"}],"versions":["v1.12.0","v1.13.0","v1.13.0-rc1","v1.13.0-rc2","v1.13.1","v1.13.2","v1.14.0","v1.14.0-rc1","v1.14.1","v1.14.2","v1.14.3"],"fixed":["1.14.4"]}],"sourceAffected":[],"references":["https://github.com/simplesamlphp/simplesamlphp/commit/b1af4e47c81bca2bee633b3f84f4fde624f359ba","https://github.com/simplesamlphp/simplesamlphp/commit/d26eb8f17dc9916a5ef2fd0a286b0fc96a561e71","https://github.com/FriendsOfPHP/security-advisories/blob/master/simplesamlphp/simplesamlphp/201606-01.yaml","https://github.com/simplesamlphp/simplesamlphp","https://simplesamlphp.org/security/201606-01"],"sources":[{"name":"OSV","id":"GHSA-v858-922f-fj9v","modified":"2024-12-03T06:07:22.402856Z","url":"https://osv.dev/vulnerability/GHSA-v858-922f-fj9v"}],"assessments":[{"source":"OSV","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:N","score":5.4}],"products":[],"remediation":[],"kev":{"status":"unavailable","checkedAt":"2026-10-28T22:00:32.546Z"},"coverage":[{"source":"NVD","status":"not-checked"},{"source":"GHSA","status":"not-checked"},{"source":"EUVD","status":"not-checked"},{"source":"EPSS","status":"not-checked"}],"evidence":[]}
