30+ Log4j Vulnerability Solutions, Tools and Resources

In August 2021, the article “Overview in 5 Minutes” stated: “Cyber ​​security, as we discussed last time, will continue to dominate the news headlines for months to come. As such, security will emerge as an important component of observation, with the addition of context to the collected telemetry data. ,

throughout the last year, Some Of they The listed observability software vendors have developed sophisticated security observability solutions. Still, your arsenal against cyber attacks and vulnerabilities shouldn’t stop here.

In addition to security overview, organizations should implement Denial of Service (DoS) and Web Application Firewall (WAF) protection, proactive scanning and other best practices; Including auditing of applications and infrastructure, VPN-enabled network security firewall (lockdown IP/port), security keys, multi-factor authentication, auto-updates, end-to-end encryption, remote backup and incident response plans in place . , With the emergence of recent exploits, we will focus on notable solutions, tools, and resources specific to Log4j vulnerabilities.

Log4j zero-day vulnerability (Log4shell)

on December 9, 2021 Alibaba Cloud Security Team Published A zero-day Vulnerability involving arbitrary code execution log4j The descriptor “Log4Shell” is given. worth has characterized it as “the biggest, most significant vulnerability of the past decade”. Apache Software Foundation (ASF) Issued safety advice on a remote code execution vulnerability (CVE-2021-44228) affecting its Log4j Java-based logging utility. vulnerability was assessed Severe severity and assigned a CVSS score of 10/10 by MITER,

Shortly thereafter, attackers began exploiting the Log4j vulnerability, prompting government cybersecurity institutions around the world, including United States Cyber ​​Security and Infrastructure Security Agency (CISA), Austria’s Computer Emergency Response Team (CERT), National Cyber ​​Security Center (NCSC) of the Netherlands, UK’s NCSC and to issue alerts advising other organizations to patch their systems immediately.

Several new vulnerabilities in the last few days – CVE-2021-45046A DoS/RCE flaw that was corrected in v2.16.0, CVE-2021-45105 A DoS hole v2.17.0 and . plugged in CVE-2021-4104 RCE vulnerability affecting Log4j v1.2 – discovered in the popular library since Log4Shell (CVE-2021-44228) was fixed by releasing Log4j v2.15.0.
