Base vector

AV:N/AC:L/Au:N/C:C/I:C/A:C

Name of the Vulnerable Software and Affected Versions MediaWiki version 1.40.0

Description The issue exists due to the lack of protection for the web page structure. A remote attacker with a low-privileged user account can exploit this by sending a malicious link to the instance administrator, allowing them to become an administrator if the instance administrator allows XML file uploads. This can lead to a security breach.

Recommendations For MediaWiki version 1.40.0, restrict access to XML file uploads to prevent exploitation until a patch is available. As a temporary workaround, consider disabling XML file uploads to minimize the risk of exploitation.
