Synopsis
MediaWiki < 1.37.3 Multiple VulnerabilitiesDescription
According to its self-reported version number, the instance of MediaWiki hosted on the remote web server is prior to 1.37.3. It is, therefore, affected by multiple vulnerabilities as follows:- The AbuseFilter extension improperly handles account blocks for certain automatically created MediaWiki user accounts, thus enabling malicious users to remain unblocked.
- The AbuseFilter extension improperly executed rules related to blocking accounts after account creation, thus blocking only the original IP used to create an account and not the account itself.
- The AbuseFilter extension improperly executed blocking rules, thus permitting user accounts who were partially or fully blocked to complete edits.
- The AbuseFilter CheckMatch API reveals suppressed edits and usernames to unprivileged users through the iteration of crafted AbuseFilter rules.
- The AbuseFilter extension incorrectly logged sensitive supression deletions which is visible to users with access to view AbuseFilter log data.
Note that the scanner has not tested for these issues but has instead relied only on the application's self-reported version number.
Solution
Upgrade to MediaWiki version 1.37.3 or later.See Also
