Descriptions

The WebDAV extension in Microsoft Internet Information Services (IIS) 5.0 on Windows 2000 SP4 does not properly decode URLs, which allows remote attackers to bypass authentication, and possibly read or create files, via a crafted HTTP request, aka "IIS 5.0 WebDAV Authentication Bypass Vulnerability," a different vulnerability than CVE-2009-1535.

La extension WebDAV en Microsoft Internet Information Services (IIS) v5.0 on Windows 2000 SP4 no decodifica adecuadamente las URLs, lo que permite a atacantes remotos evitar la autenticación, y posiblemente leer o crear ficheros, a través de una petición HTTP manipulada, también conocido como "Vulnerabilidad para evitar la autenticación de WebDAV en IIS v5.0"
