CVE-2020-35510

jboss-remoting: Threads hold up forever in the EJB server by suppressing the ack from an EJB client

A flaw was found in jboss-remoting in versions before 5.0.20.SP1-redhat-00001. A malicious attacker could cause threads to hold up forever in the EJB server by writing a sequence of bytes corresponding to the expected messages of a successful EJB client request, but omitting the ACK messages, or just tamper with jboss-remoting code, deleting the lines that send the ACK message from the EJB client code resulting in a denial of service. The highest threat from this vulnerability is to system availability.

mysql-connector-java: allows unauthenticated attacker with network access via multiple protocols to compromise MySQL Connectors which could result in unauthorized update, insert or delete

Vulnerability in the MySQL Connectors product of Oracle MySQL (component: Connector/J). Supported versions that are affected are 8.0.19 and prior and 5.1.48 and prior. Difficult to exploit vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise MySQL Connectors. Successful attacks require human interaction from a person other than the attacker. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of MySQL Connectors accessible data as well as unauthorized read access to a subset of MySQL Connectors accessible data and unauthorized ability to cause a partial denial of service (partial DOS) of MySQL Connectors. CVSS 3.0 Base Score 5.0 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:R/S:U/C:L/I:L/A:L).

undertow: special character in query results in server errors

A flaw was found in the Undertow AJP connector. Malicious requests and abrupt connection closes could be triggered by an attacker using query strings with non-RFC compliant characters resulting in a denial of service. The highest threat from this vulnerability is to system availability. This affects Undertow 2.1.5.SP1, 2.0.33.SP2, and 2.2.3.SP1.

jetty: buffer not correctly recycled in Gzip Request inflation

In Eclipse Jetty version 9.4.0.RC0 to 9.4.34.v20201102, 10.0.0.alpha0 to 10.0.0.beta2, and 11.0.0.alpha0 to 11.0.0.beta2, if GZIP request body inflation is enabled and requests from different clients are multiplexed onto a single connection, and if an attacker can send a request with a body that is received entirely but not consumed by the application, then a subsequent request on the same connection will see that body prepended to its body. The attacker will not see any data but may inject data into the body of the subsequent request.

jetty: local temporary directory hijacking vulnerability

In Eclipse Jetty versions 1.0 thru 9.4.32.v20200930, 10.0.0.alpha1 thru 10.0.0.beta2, and 11.0.0.alpha1 thru 11.0.0.beta2O, on Unix like systems, the system's temporary directory is shared between all users on that system. A collocated user can observe the process of creating a temporary sub directory in the shared temporary directory and race to complete the creation of the temporary subdirectory. If the attacker wins the race then they will have read and write permission to the subdirectory used to unpack web applications, including their WEB-INF/lib jar files and JSP files. If any code is ever executed out of this temporary directory, this can lead to a local privilege escalation vulnerability.

wildfly-core: memory leak in WildFly host-controller in domain mode while not able to reconnect to domain-controller

A memory leak flaw was found in WildFly in all versions up to 21.0.0.Final, where host-controller tries to reconnect in a loop, generating new connections which are not properly closed while not able to connect to domain-controller. This flaw allows an attacker to cause an Out of memory (OOM) issue, leading to a denial of service. The highest threat from this vulnerability is to system availability.

apache-flink: JMX information disclosure vulnerability

A vulnerability in Apache Flink (1.1.0 to 1.1.5, 1.2.0 to 1.2.1, 1.3.0 to 1.3.3, 1.4.0 to 1.4.2, 1.5.0 to 1.5.6, 1.6.0 to 1.6.4, 1.7.0 to 1.7.2, 1.8.0 to 1.8.3, 1.9.0 to 1.9.2, 1.10.0) where, when running a process with an enabled JMXReporter, with a port configured via metrics.reporter.reporter_name>.port, an attacker with local access to the machine and JMX port can execute a man-in-the-middle attack using a specially crafted request to rebind the JMXRMI registry to one under the attacker's control. This compromises any connection established to the process via JMX, allowing extraction of credentials and any other transferred data.

apache-commons-configuration: uncontrolled class instantiation when loading YAML files

Apache Commons Configuration uses a third-party library to parse YAML files which by default allows the instantiation of classes if the YAML includes special statements. Apache Commons Configuration versions 2.2, 2.3, 2.4, 2.5, 2.6 did not change the default settings of this library. So if a YAML file was loaded from an untrusted source, it could therefore load and execute code out of the control of the host application.

olingo-odata: Server side request forgery in AsyncResponseWrapperImpl

Apache Olingo versions 4.0.0 to 4.7.0 provide the AsyncRequestWrapperImpl class which reads a URL from the Location header, and then sends a GET or DELETE request to this URL. It may allow to implement a SSRF attack. If an attacker tricks a client to connect to a malicious server, the server can make the client call any URL including internal resources which are not directly accessible by the attacker.

undertow: AJP File Read/Inclusion Vulnerability

A file inclusion vulnerability was found in the AJP connector enabled with a default AJP configuration port of 8009 in Undertow version 2.0.29.Final and before and was fixed in 2.0.30.Final. A remote, unauthenticated attacker could exploit this vulnerability to read web application files from a vulnerable server. In instances where the vulnerable server allows file uploads, an attacker could upload malicious JavaServer Pages (JSP) code within a variety of file types and trigger this vulnerability to gain remote code execution.
