Descriptions
The WebDAV extension in Microsoft Internet Information Services (IIS) 5.1 and 6.0 allows remote attackers to bypass URI-based protection mechanisms, and list folders or read, create, or modify files, via a %c0%af (Unicode / character) at an arbitrary position in the URI, as demonstrated by inserting %c0%af into a "/protected/" initial pathname component to bypass the password protection on the protected\ folder, aka "IIS 5.1 and 6.0 WebDAV Authentication Bypass Vulnerability," a different vulnerability than CVE-2009-1122.
La extensión de WebDAV en Microsoft Internet Information Services (IIS) v5.1 y v6.0 permite a atacantes remotos eludir los mecanismos de protección basados en URL, y listar carpetas o leer, crear o modificar archivos, a través de un %c0%af (Unicode / carácter) en una posición arbitraria en la URL, como se ha demostrado mediante la inserción de %c0%af en la ruta inicial de componente "/protected/" para evitar la protección por contraseña en la carpeta protected\ , alias "IIS v5.1 y v6.0 Vulnerabilidad de evasión de autenticación WebDAV".
