Vendavo Response to Log4Shell Remote Code Execution Vulnerability

David Edwards< David Edwards December 13, 2021

On December 9, 2021, a zero-day remote code execution (RCE) vulnerability in a popular open-source Java logging library (Apache Log4j 2) was announced in a LunaSec blogpost. The security vulnerability goes by the name of Log4Shell and has since been assigned the Common Vulnerabilities and Exposures (CVE) reference of CVE-2021-44228. The range of software companies and service providers impacted by Log4Shell is quite expansive given the prevalence of Java technology and the popularity of Log4J.

On December 10, 2021, at approximately 3:00 pm Pacific Time (23:00 GMT), the incident response team at Vendavo notified Vendavo Cloud customers of emergency downtime patching and remediation efforts in response to the Log4Shell vulnerability. Those customers were again notified at the completion of patching and configuration updates. No breach of customer data or personal data was identified. 

The remediation activities conducted over the course of the weekend, December 11 and 12, represented proactive efforts to avert and defend customer systems and data against the immediate threat posed by the Log4Shell RCE vulnerability. We continue to monitor all systems as standard procedure and will adjust our incident response if necessary.
