Microsoft IIS Unicode Requests to WebDAV Multiple Authentication Bypass Vulnerabilities

반응형



Microsoft Internet Information Service (IIS) is prone to multiple authentication-bypass vulnerabilities because the application fails to properly enforce access restrictions on certain requests to password-protected WebDAV folders.

An attacker can exploit these issues to gain unauthorized access to protected WebDAV resources, which may lead to other attacks.
