VAR-201911-1358

Vulnerability from variot - Updated: 2023-12-18 13:01

Embedthis GoAhead before 5.0.1 mishandles redirected HTTP requests with a large Host header. The GoAhead WebsRedirect uses a static host buffer that has a limited length and can overflow. This can cause a copy of the Host header to fail, leaving that buffer uninitialized, which may leak uninitialized data in a response. Embedthis GoAhead Contains a buffer error vulnerability.Information may be obtained. Embedthis Software GoAhead is an embedded Web server of American Embedthis Software company. A buffer error vulnerability exists in Embedthis Software GoAhead versions prior to 5.0.1. This vulnerability stems from the incorrect verification of data boundaries when the network system or product performs operations on the memory, resulting in incorrect read and write operations to other associated memory locations. Attackers can exploit this vulnerability to cause buffer overflow or heap overflow, etc
