3.7 · LOW Actively Exploited
Published Apr 17, 2013 oracle CWE-284

Overview

CVE-2013-2423 is a low-severity vulnerability affecting oracle jre. It was published on April 17, 2013 and has a CVSS 3.1 base score of 3.7 (LOW). This vulnerability is listed in CISA's Known Exploited Vulnerabilities catalog, indicating active exploitation in the wild.

This vulnerability has a CVSS 3.1 base score of 3.7, rated LOW. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical Description

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.

Remediation

Check the references section for vendor advisories and patches from oracle. Update jre to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
