Is Symantec Endpoint Protection vulnerable to Spring4shell CVE-2022-22965

Products

• Endpoint Protection

Issue/Introduction

Researchers have found a remote code execution 0-day vulnerability (dubbed Spring4Shell and SpringShell) in the Spring Core Java framework that allows unauthenticated remote code execution. A proof of concept was leaked for a short time on Github and although promptly removed, some were able to swiftly download it. It's been reposted on various platforms, making it available to the public.

Environment

Release : 14.3 RU4

Cause

This RCE 0-day vulnerability exists in the Spring Core with the JDK version greater than or equal to 9.0. It allows an unauthenticated attacker to execute arbitrary code on the target system. The Spring Framework is a popular Java platform that provides comprehensive infrastructure support for developing Java applications.

Resolution

Symantec Security Response has published the following protections based on proof of concepts (POC).

File-based

• Hacktool 
• Hacktool.Spring4shell

Network-based

• Audit: Spring Core Spring4Shell Activity
• Web Attack: Spring Core Spring4Shell Activity 2 

Policy-based

• Data Center Security (DCS) Intrusion Prevention (with default policies) provides zero-day protection against exploitation of the Spring4Shell vulnerability.

 

Note: Spring Framework versions 5.3.18 and 5.2.20, which address the vulnerability, are now available. Also temporary remediation steps were provided earlier by researchers at Praetorian.
