Enterprises Had Patched 45% of Vulnerable Cloud Resources 10 Days After Log4Shell Disclosure

Summary
An analysis of more than 200 enterprise cloud environments found 93% at risk from Log4Shell and an average 45% of vulnerable cloud resources patched by Dec. 20, 2021.
Key points
- Wiz and EY analyzed more than 200 enterprise cloud environments; 93% were at risk from Log4Shell.
- By Dec. 20, 2021, organizations had patched an average of 45% of vulnerable cloud resources, up from 30% six days after public disclosure.
- Financial services organizations had patched an average 50% of vulnerable assets, compared with 34% in manufacturing.
- The analysis found 20% of at-risk workloads had high cloud-account privileges and 7% were internet-exposed.
- The article says 45% of vulnerable machines lacked endpoint protection agents, which may not cover all cloud resources.
- Remediation was complicated by large numbers of workloads, embedded or packaged Log4j dependencies, vendor update delays, and subsequent Log4j vulnerabilities. The article names CVE-2021-40546 and CVE-2021-45105.
