Embedthis: >> Goahead >> 4.0.0 Security Vulnerabilities
The code that performs password matching when using 'Basic' HTTP authentication does not use a constant-time memcmp and has no rate-limiting. This means that an unauthenticated network attacker can brute-force the HTTP basic password, byte-by-byte, by recording the webserver's response time until the unauthorized (401) response.

An issue was discovered in GoAhead 4.x and 5.x before 5.1.5. In the file upload filter, user form variables can be passed to CGI scripts without being prefixed with the CGI prefix. This permits tunneling untrusted environment variables into vulnerable CGI scripts.

The HTTP Digest Authentication in the GoAhead web server before 5.1.2 does not completely protect against replay attacks. This allows an unauthenticated remote attacker to bypass authentication via capture-replay if TLS is not used to protect the underlying communication channel.

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.

In http.c in Embedthis GoAhead before 4.1.1 and 5.x before 5.0.1, a header parsing vulnerability causes a memory assertion, out-of-bounds memory reference, and potential DoS, as demonstrated by a colon on a line by itself.

An issue was discovered in Embedthis GoAhead before 4.0.1 and Appweb before 7.0.2. The server mishandles some HTTP request fields associated with time, which results in a NULL pointer dereference, as demonstrated by If-Modified-Since or If-Unmodified-Since with a month greater than 11.

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.
