CVE-2020-15164 (GCVE-0-2020-15164)

Vulnerability from cvelistv5 – Published: 2020-08-28 17:05 – Updated: 2024-08-04 13:08

Title

Authentication Bypass in Scratch Login (mediawiki-scratch-login)

Summary

in Scratch Login (MediaWiki extension) before version 1.1, any account can be logged into by using the same username with leading, trailing, or repeated underscore(s), since those are treated as whitespace and trimmed by MediaWiki. This affects all users on any wiki using this extension. Since version 1.1, comments by users whose usernames would be trimmed on MediaWiki are ignored when searching for the verification code.

Severity

10 (Critical)
