IBM WebSphere Application Server 7.0, 8.0, 8.5, and 9.0 is vulnerable to cross-site request forgery which could allow an attacker to execute malicious and unauthorized actions transmitted from a user that the website trusts. IBM X-Force ID: 123669.

In Apache Log4j 2.x before 2.8.2, when using the TCP socket server or UDP socket server to receive serialized log events from another application, a specially crafted binary payload can be sent that, when deserialized, can execute arbitrary code.

A deserialization flaw was discovered in the jackson-databind, versions before 2.6.7.1, 2.7.9.1 and 2.8.9, which could allow an unauthenticated user to perform code execution by sending the maliciously crafted input to the readValue method of the ObjectMapper.

Remote code execution is possible with Apache Tomcat before 6.0.48, 7.x before 7.0.73, 8.x before 8.0.39, 8.5.x before 8.5.7, and 9.x before 9.0.0.M12 if JmxRemoteLifecycleListener is used and an attacker can reach JMX ports. The issue exists because this listener wasn't updated for consistency with the CVE-2016-3427 Oracle patch that affected credential types.

IBM WebSphere Application Server 8.0, 8.5, 8.5.5, and 9.0 using OpenID Connect (OIDC) configured with a Trust Association Interceptor (TAI) could allow a user to gain elevated privileges on the system. IBM Reference #: 1999293.

IBM WebSphere Application Server 7.0, 8.0, and 9.0 is vulnerable to cross-site scripting. This vulnerability allows users to embed arbitrary JavaScript code in the Web UI thus altering the intended functionality potentially leading to credentials disclosure within a trusted session. IBM Reference #: 1997743

IBM WebSphere Application Server may be vulnerable to a denial of service, caused by allowing serialized objects from untrusted sources to run and cause the consumption of resources.

IBM WebSphere Application Server is vulnerable to cross-site scripting. This vulnerability allows users to embed arbitrary JavaScript code in the Web UI thus altering the intended functionality potentially leading to credentials disclosure within a trusted session.

IBM WebSphere Application Server (WAS) 7.0 before 7.0.0.43, 8.0 before 8.0.0.13, 8.5 before 8.5.5.11, 9.0 before 9.0.0.2, and Liberty before 16.0.0.4 allows remote authenticated users to execute arbitrary Java code via a crafted serialized object.

IBM WebSphere Application Server (WAS) 7.x before 7.0.0.43, 8.0.x before 8.0.0.13, 8.5.x before 8.5.5.11, 9.0.x before 9.0.0.2, and Liberty before 16.0.0.3 mishandles responses, which allows remote attackers to obtain sensitive information via unspecified vectors.
