Description

NVD

Unspecified vulnerability in the Java Runtime Environment (JRE) component in Oracle Java SE 7 Update 17 and earlier, and OpenJDK 7, allows remote attackers to affect integrity via unknown vectors related to HotSpot. NOTE: the previous information is from the April 2013 CPU. Oracle has not commented on claims from the original researcher that this vulnerability allows remote attackers to bypass permission checks by the MethodHandles method and modify arbitrary public final fields using reflection and type confusion, as demonstrated using integer and double fields to disable the security manager.

What CISA says to do

Public module

Metasploit lists a public excellent-rank module for this CVE: Java Applet Reflection Type Confusion Remote Code Execution (multi/browser/java_jre17_reflection_types). A module existing is not the same as active exploitation; see metasploit.com.
