CVE-2024-43369

Persistent Cross-site Scripting in Ibexa RichText Field Type

Impact

### Impact The validator for the RichText fieldtype blocklists `javascript:` and `vbscript:` in links to prevent XSS. This can leave other options open, and the check can be circumvented using upper case. Content editing permissions for RichText content is required to exploit this vulnerability, which typically means Editor role or higher. The fix implements an allowlist instead, which allows only approved link protocols. The new check is case insensitive. ### Patches - See "Patched versions". - https://github.com/ibexa/fieldtype-richtext/commit/59e9c1a9da60597f60cf7338bf289dccaa7e27ca (and follow-up https://github.com/ibexa/fieldtype-richtext/commit/0a3b830e8806d5169f697351fdc48ffd95a25c67) ### Workarounds None. ### References - Same issue in v3.3: https://github.com/ezsystems/ezplatform-richtext/security/advisories/GHSA-rhm7-7469-rcpw - Ibexa advisory: https://developers.ibexa.co/security-advisories/ibexa-sa-2024-005-persistent-xss-in-richtext ### Credit This vulnerability was discovered and reported to Ibexa by Alec Romano: https://github.com/4rdr We thank them for reporting it responsibly to us.
