CVSS v3.1
Official Description
In Mahara before 20.04.5, 20.10.3, 21.04.2, and 21.10.0, adjusting the path component for the page help file allows attackers to bypass the intended access control for HTML files via directory traversal. It replaces the - character with the / character.
Technical Analysis
CVE-2021-43264 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
