An issue was discovered in the OATHAuth extension in MediaWiki before 1.31.10 and 1.32.x through 1.34.x before 1.34.4. For Wikis using OATHAuth on a farm/cluster (such as via CentralAuth), rate limiting of OATH tokens is only done on a single site level. Thus, multiple requests can be made across many wikis/sites concurrently.

There are packages installed that are affected by a vulnerability referenced in the following CVE:

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora update system website.
Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Multiple security issues were discovered in MediaWiki, a website engine for collaborative work: SpecialUserRights could leak whether a user existed or not, multiple code paths lacked HTML sanitisation allowing for cross-site scripting and TOTP validation applied insufficient rate limiting against brute force attempts.
