Steps
Written by AI from the record- Check whether you run Claroline 13.5.7 or earlier and whether administrators can open uploaded SVG files.
- Ask your Claroline vendor or support provider for the fixed version; no confirmed fixed version is currently available.
- Until a fix is available, block SVG uploads or prevent administrators from opening uploaded SVG files, and review administrator accounts for unexpected additions.
What it is
From the CVE record
Claroline 13.5.7 and prior allows an authenticated attacker to elevate privileges via the arbitrary creation of a privileged user. By combining the XSS vulnerability present in several upload forms and a javascript request to the present API, it is possible to trigger the creation of a user with administrative rights by opening an SVG file as an administrator user.
In plain language
Written by AI from the recordClaroline 13.5.7 and earlier can let a logged-in attacker gain administrator access if an administrator opens a malicious SVG upload, so affected businesses should act.
Authenticated privilege escalation in Claroline through stored XSS in upload forms, where opening a malicious SVG as an administrator can trigger an API request that creates a privileged user.
