CVE-1999-1087

Summary

CVE-1999-1087 refers to a vulnerability in Internet Explorer 4 that allows remote servers to bypass security restrictions. The issue arises due to the browser's treatment of a 32-bit number in a URL as a hostname instead of an IP address. Consequently, web pages containing dotless IP addresses are subjected to Local Intranet Zone settings, enabling unauthorized activities such as data theft or unintended modifications. This vulnerability poses a significant risk to users who visit malicious websites with dotless IP addresses in their URLs.
