HIGHEmbedthis Appweb < 7.0.2 and GoAhead < 4.0.1 - Denial of Service via Malformed IPv6 Host Header
Title source: llmDescription
An issue was discovered in Embedthis GoAhead before 4.0.1 and Appweb before 7.0.2. An HTTP POST request with a specially crafted "Host" header field may cause a NULL pointer dereference and thus cause a denial of service, as demonstrated by the lack of a trailing ']' character in an IPv6 address.
