CVE-1999-0725

Summary

CVE-1999-0725 is a vulnerability affecting Microsoft's Internet Information Services (IIS) when it is configured with a default language of Chinese, Korean, or Japanese. This issue allows remote attackers to access the source code of certain files, a process known as "Double Byte Code Page" vulnerability. The vulnerability arises due to the way IIS handles multi-byte character sets, enabling an attacker to bypass intended access restrictions and view sensitive information. This issue poses a significant risk, particularly in environments where IIS is used to host websites with sensitive data. Attackers can exploit this vulnerability by sending specially crafted HTTP requests to the affected server, potentially leading to information disclosure and further exploitation. To mitigate this risk, it is recommended that IIS be configured with a language setting other than Chinese, Korean, or Japanese, and that all applicable security patches be installed.
