CVE-2024-43369 Information

Description

Ibexa RichText Field Type is a Field Type for supporting rich formatted text stored in a structured XML format. In versions on the 4.6 branch prior to 4.6.10 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. Version 4.6.10 contains a patch for this issue. No known workarounds are available.
