VAR-200705-0069

Vulnerability from variot - Updated: 2025-04-10 23:09

The "hit-highlighting" functionality in webhits.dll in Microsoft Internet Information Services (IIS) Web Server 5.0 only uses Windows NT ACL configuration, which allows remote attackers to bypass NTLM and basic authentication mechanisms and access private web directories via the CiWebhitsfile parameter to null.htw. Microsoft IIS is prone to an authentication-bypass vulnerability due to its implementation of 'Hit-highlighting' functionality. Attackers can exploit this issue to access private files hosted on an IIS website. Successful exploits may allow attackers to gain access to potentially sensitive information. Other attacks are possible. NOTE: Presumably, accessing a Trusted Zone may allow attackers to execute commands; this has not been confirmed
