Vulnerabilidades

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. 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.

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.

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=,".

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…

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.

Mbedthis AppWeb HTTP server before 1.0.2 allows remote attackers to cause a denial of service (crash) via an empty OPTIONS request.

Information leak in Mbedthis AppWeb HTTP server 1.0 through 1.1.2 allows remote attackers to obtain sensitive information via a user message that is generated when Mbedthis denies access.

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 1.0.2 allows remote attackers to cause a denial of service (crash) via a GET request containing an MS-DOS device name such as COM1.

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.
