CISA launches webpage, repository on Apache Log4j vulnerability

The Cybersecurity and Infrastructure Security Agency has created a webpage to provide the latest public information and vendor-supplied advisories on a critical remote code execution vulnerability affecting Apache Log4j software library versions 2.0-beta9 to 2.14.1. CISA urges organizations to review the webpage and immediately upgrade to Log4j version 2.15.0 or apply the appropriate vendor-recommended mitigations, because an unauthenticated remote actor could exploit this vulnerability to take control of an affected system. CISA and its Joint Cyber Defense Collaborative partners are tracking the vulnerability, and CISA will continue to update the webpage as additional information becomes available. Log4j is broadly used in a variety of consumer and enterprise services, websites, applications and operational technology products to log security and performance information.
