Description Preview
An issue was discovered in Embedthis GoAhead before 4.0.1 and Appweb before 7.0.2. This vulnerability arises when an HTTP POST request contains a specially crafted "Host" header field that lacks a trailing ']' character in an IPv6 address. This malformed request can result in a NULL pointer dereference, leading to a denial of service condition.
Overview
This vulnerability affects Embedthis GoAhead versions prior to 4.0.1 and Appweb versions prior to 7.0.2. By exploiting this issue, an attacker can cause a denial of service by sending a malicious HTTP POST request with a specific format in the "Host" header field.
Remediation

By applying the latest patches and updates, organizations can protect their systems from potential NULL pointer dereference issues and denial of service attacks.
