An issue was discovered in src/http/httpLib.c in EmbedThis Appweb Community Edition 8.2.1, allows attackers to cause a denial of service via the stream paramter to the parseUri function.

Appweb before 7.2.2 and 8.x before 8.1.0, when built with CGI support, mishandles an HTTP request with a Range header that lacks an exact range. This may result in a NULL pointer dereference and cause a denial of service.

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.

The Embedthis HTTP library, and Appweb versions before 7.0.3, have a logic flaw related to the authCondition function in http/httpLib.c. With a forged HTTP request, it is possible to bypass authentication for the form and digest login types.

Embedthis Appweb before 4.6.6 and 5.x before 5.2.1 allows remote attackers to cause a denial of service (NULL pointer dereference) via a Range header with an empty value, as demonstrated by "Range: x=,".

Mbedthis AppWeb before 2.2.2 enables the HTTP TRACE method, which has unspecified impact probably related to remote information leaks and cross-site tracing (XST) attacks, a related issue to CVE-2004-2320 and CVE-2005-3398.

Format string vulnerability in the MprLogToFile::logEvent function in Mbedthis AppWeb 2.0.5-4, when the build supports logging but the configuration disables logging, allows remote attackers to cause a denial of service (daemon crash) via format string specifiers in the HTTP scheme, as demonstrated by a "GET %n://localhost:80/" request.

Mbedthis AppWeb HTTP server before 1.1.3 allows remote attackers to bypass access restrictions via a URI with mixed case characters.

Mbedthis AppWeb HTTP server before 1.1.3 allows remote attackers to obtain the source code for scripts via a (1) trailing dot (".") or (2) trailing space in an HTTP request.
