Based on what we know now, can Waratek Java products mitigate this vulnerability?

Only Waratek provides a fully programmable security platform, ARMR, that can remediate vulnerabilities, including CVE-2021-44228.

Customers who have applied ARMR’s Socket:Connect rules to restrict connections to external locations have immediate mitigation for this vulnerability. Additionally, Waratek is providing all customers an ARMR Virtual Remediation Patch which permanently remediates this vulnerability for live, executing Log4j code inside any workload or software version.

Waratek recommends all customers to add the ARMR Virtual Remediation Patch for CVE-2021-44228 to their default ARMR security policy for all applications to permanently remediate the vulnerable code that enables this vulnerability. As with all ARMR Rules and Virtual Patches, this permanent remediation can be applied live to any workload and does not require service restart or downtime to achieve permanent remediation.

Waratek Customer Success Managers are contacting all customers to assist in applying the instant ARMR Remediation Patch to permanently remediate this vulnerability for all workloads and applications. For assistance in deploying the patch, please contact Customer Success at [email protected].
