jetty: Incorrect header handling

In Eclipse Jetty Server, versions 9.2.x and older, 9.3.x (all non HTTP/1.x configurations), and 9.4.x (all HTTP/1.x configurations), when presented with two content-lengths headers, Jetty ignored the second. When presented with a content-length and a chunked encoding header, the content-length was ignored (as per RFC 2616). If an intermediary decided on the shorter length, but still passed on the longer body, then body content could be interpreted by Jetty as a pipelined request. If the intermediary was imposing authorization, the fake pipelined request would bypass that authorization.

jetty: HTTP request smuggling

In Eclipse Jetty, versions 9.2.x and older, 9.3.x (all configurations), and 9.4.x (non-default configuration with RFC2616 compliance enabled), transfer-encoding chunks are handled poorly. The chunk length parsing was vulnerable to an integer overflow. Thus a large chunk size could be interpreted as a smaller chunk size and content sent as chunk body could be interpreted as a pipelined request. If Jetty was deployed behind an intermediary that imposed some authorization and that intermediary allowed arbitrarily large chunks to be passed on unchanged, then this flaw could be used to bypass the authorization imposed by the intermediary as the fake pipelined request would not be interpreted by the intermediary as a request.

jetty: HTTP request smuggling using the range header

In Eclipse Jetty, versions 9.2.x and older, 9.3.x (all configurations), and 9.4.x (non-default configuration with RFC2616 compliance enabled), HTTP/0.9 is handled poorly. An HTTP/1 style request line (i.e. method space URI space version) that declares a version of HTTP/0.9 was accepted and treated as a 0.9 request. If deployed behind an intermediary that also accepted and passed through the 0.9 version (but did not act on it), then the response sent could be interpreted by the intermediary as HTTP/1 headers. This could be used to poison the cache if the server allowed the origin client to generate arbitrary content in the response.

In Eclipse Mosquitto version from 1.0 to 1.4.15, a Null Dereference vulnerability was found in the Mosquitto library which could lead to crashes for those applications using the library.

In Eclipse Mosquitto 1.4.15 and earlier, a Memory Leak vulnerability was found within the Mosquitto Broker. Unauthenticated clients can send crafted CONNECT packets which could cause a denial of service in the Mosquitto Broker.

The Eclipse Mosquitto broker up to version 1.4.15 does not reject strings that are not valid UTF-8. A malicious client could cause other clients that do reject invalid UTF-8 strings to disconnect themselves from the broker by sending a topic string which is not valid UTF-8, and so cause a denial of service for the clients.

In Eclipse Mosquitto 1.4.14, if a Mosquitto instance is set running with a configuration file, then sending a HUP signal to server triggers the configuration to be reloaded from disk. If there are lots of clients connected so that there are no more file descriptors/sockets available (default limit typically 1024 file descriptors on Linux), then opening the configuration file will fail.

In Eclipse Mosquitto 1.4.14, a user can shutdown the Mosquitto server simply by filling the RAM memory with a lot of connections with large payload. This can be done without authentications if occur in connection phase of MQTT protocol.

QNAP NAS application Media Streaming add-on version 421.1.0.2, 430.1.2.0, and earlier does not utilize CSRF protections.

QNAP NAS application Proxy Server through version 1.2.0 does not authenticate requests properly. Successful exploitation can lead to change of the settings of Proxy Server.

QNAP NAS application Media Streaming add-on version 421.1.0.2, 430.1.2.0, and earlier does not authenticate requests properly. Successful exploitation could lead to change of the Media Streaming settings, and leakage of sensitive information of the QNAP NAS.

QNAP NAS application Proxy Server through version 1.2.0 allows remote attackers to run arbitrary OS commands against the system with root privileges.

Cross-site scripting (XSS) vulnerability in QNAP NAS application Proxy Server through version 1.2.0 allows remote attackers to inject arbitrary web script or HTML.

QNAP NAS application Proxy Server through version 1.2.0 does not utilize CSRF protections.

Cross-site scripting (XSS) vulnerability in QNAP NAS application Media Streaming add-on version 421.1.0.2, 430.1.2.0, and earlier allows remote attackers to inject arbitrary web script or HTML. The injected code will only be triggered by a crafted link, not the normal page.

QNAP Qfinder Pro 6.1.0.0317 and earlier may expose sensitive information contained in NAS devices. If exploited, this may allow attackers to further compromise the device.
