Affected versions of the vulnerable multi-factor authentication extension
Summary
This vulnerability occurs because the MFA extension does not properly reset generated MFA codes after successful authentication. Attackers can exploit this flaw to bypass MFA protection for subsequent login attempts by submitting an empty string as the MFA code. Successful exploitation allows attackers to gain unauthorized access to protected user accounts, completely negating MFA security. This poses a severe risk to any organization using the affected extension.
Remediation
Update the affected MFA extension to the latest patched version from the vendor that fixes the improper code reset issue. If no patch is available, disable the extension immediately and switch to a trusted alternative MFA provider. Audit account login logs for suspicious unrecognized access attempts to detect prior exploitation.
