In Eclipse Jetty versions 9.4.0 through 9.4.8, when using the optional Jetty provided FileSessionDataStore for persistent storage of HttpSession details, it is possible for a malicious user to access/hijack other HttpSessions and even delete unmatched HttpSessions present in the FileSystem's storage for the FileSessionDataStore.
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 1.4.15 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.
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.
Eclipse XML parser for the Eclipse IDE versions 2017.2.5 and earlier was found vulnerable to an XML External Entity attack. An attacker can exploit the vulnerability by implementing malicious code on Androidmanifest.xml.
The network enabled distribution of Kura before 2.1.0 takes control over the device's firewall setup but does not allow IPv6 firewall rules to be configured. Still the Equinox console port 5002 is left open, allowing to log into Kura without any user credentials over unencrypted telnet and executing commands using the Equinox "exec" command. As the process is running as "root" full control over the device can be acquired. IPv6 is also left in auto-configuration mode, accepting router advertisements automatically and assigns a MAC address based IPv6 address.
In Mosquitto before 1.4.12, pattern based ACLs can be bypassed by clients that set their username/client id to '#' or '+'. This allows locally or remotely connected clients to access MQTT topics that they do have the rights to. The same issue may be present in third party authentication/access control plugins for Mosquitto.
In Mosquitto through 1.4.12, mosquitto.db (aka the persistence file) is world readable, which allows local users to obtain sensitive MQTT topic information.
Jetty through 9.4.x is prone to a timing channel in util/security/Password.java, which makes it easier for remote attackers to obtain access by observing elapsed times before rejection of incorrect passwords.
