CVE-2017-3241

52

FAUCET Score

CVE-2017-3241 is a critical vulnerability in the RMI subcomponent of Oracle Java SE, Java SE Embedded, and JRockit, affecting versions 6u131, 7u121, 8u112, 8u111, and R28.3.12 respectively. This unauthenticated flaw, exploitable remotely via multiple protocols, allows for a complete takeover of the affected Java environments, impacting confidentiality, integrity, and availability. Despite its high CVSS v3.0 score of 9.0 (Critical) and high EPSS score, exploitation is difficult and requires supplying data to specific APIs without using untrusted Java Web Start applications or applets. While no active exploitation is noted in KEV and there's minimal community discussion or media coverage, a denial-of-service exploit for OpenJDK Runtime Environment 1.8.0_112-b15 exists on ExploitDB.
