CVE-2018-10682: Wildfly: Remote code execution

CVE-2018-10682 is rated critical with a CVSS v3.0 base score of 9.8 and affects Wildfly. Per its scoring, it can be exploited over the network, without authentication, without any user interaction. The scored impact on confidentiality, integrity and availability is the highest available.

Vulnerability description

An issue was discovered in WildFly 10.1.2.Final. It is possible for an attacker to access the administration panel on TCP port 9990 without any authentication using "anonymous" access that is automatically created. Once logged in, a misconfiguration present by default (auto-deployment) permits an anonymous user to deploy a malicious .war file, leading to remote code execution. NOTE: the vendor indicates that anonymous access is not available in the default installation; however, it remains optional because there are several use cases for it, including development environments and network architectures that have a proxy server for access control to the WildFly server
