{"id":"CVE-2024-45399","summary":"Indico has a Cross-Site-Scripting during account creation","details":"Indico is an event management system that uses Flask-Multipass, a multi-backend authentication system for Flask. In Indico prior to version 3.3.4, corresponding to Flask-Multipass prior to version 0.5.5, there is a Cross-Site-Scripting vulnerability during account creation when redirecting to the `next` URL. Exploitation requires initiating the account creation process with a maliciously crafted link, and then finalizing the signup process. Because of this, it can only target newly created (and thus unprivileged) Indico users. Indico 3.3.4 upgrades the dependency on Flask-Multipass to version 0.5.5, which fixes the issue. Those who build the Indico package themselves and cannot upgrade can update the `flask-multipass` dependency to `\u003e=0.5.5` which fixes the vulnerability. Otherwise one could configure one's web server to disallow requests containing a query string with a `next` parameter that starts with `javascript:`.","aliases":["GHSA-rrqf-w74j-24ff","PYSEC-2024-90"],"modified":"2026-04-10T05:17:44.780484Z","published":"2024-09-04T20:12:20.457Z","database_specific":{"cna_assigner":"GitHub_M","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/45xxx/CVE-2024-45399.json","cwe_ids":["CWE-1395","CWE-79"]},"references":[{"type":"WEB","url":"https://github.com/indico/indico/releases/tag/v3.3.4"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/45xxx/CVE-2024-45399.json"},{"type":"ADVISORY","url":"https://github.com/indico/indico/security/advisories/GHSA-rrqf-w74j-24ff"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-45399"},{"type":"FIX","url":"https://github.com/indico/flask-multipass/commit/0bdcf656d469e5f675cb56fd644d82fea3a97c2a"},{"type":"FIX","url":"https://github.com/indico/indico/commit/7dcb573837b9fd09d95f74d1baeae225b164cc8f"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/indico/flask-multipass","events":[{"introduced":"0"},{"fixed":"0bdcf656d469e5f675cb56fd644d82fea3a97c2a"}]}],"versions":["v0.3","v0.3.1","v0.3.2","v0.3.3","v0.3.4","v0.3.5","v0.3.dev0","v0.3.dev1","v0.3.dev2","v0.3.dev3","v0.3.dev4","v0.3.dev5","v0.4","v0.4.1","v0.4.2","v0.4.3","v0.4.4","v0.4.5","v0.4.6","v0.4.7","v0.4.8","v0.4.9","v0.5","v0.5.1","v0.5.2","v0.5.3","v0.5.4"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2024-45399.json"}},{"ranges":[{"type":"GIT","repo":"https://github.com/indico/indico","events":[{"introduced":"0"},{"fixed":"b22a7f66d21f1d6591257e07693b9ab1b855f14a"}]}],"versions":["v0.97b","v0.97b2","v1.9.11.dev3","v1.9.11.dev6","v1.9.11.dev7","v1.9.11.dev8","v1.9.11.dev9","v1.9.9","v2.0a1","v2.0rc1","v2.1","v2.1a1","v2.1a2","v2.1a3","v2.1b1","v2.1rc1","v2.1rc2","v2.1rc3","v2.1rc4","v2.1rc5","v2.1rc6","v2.2","v2.3","v2.3.1","v3.0","v3.0rc1","v3.0rc2","v3.2","v3.2.1","v3.2.2","v3.2.3","v3.2.4","v3.2.5","v3.2.6","v3.2.6+docs","v3.3","v3.3.1","v3.3.2","v3.3.3"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2024-45399.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N"}]}
