According to multiple sources, Alibaba’s cloud security team detected a flaw in the Log4j software in the past week. It poses a threat to numerous online companies. Research shows threat actors have been exploiting it since the beginning of the month.
The vulnerability, known as CVE-2021-44228 or “Log4Shell” is a remote code execution issue affecting Log4j 2. Many describe it as one of the most serious software flaws in recent memory.
Businesses across the world are rushing to patch their systems. Joe Sullivan, the CSO at CloudFlare, which is a leader in CDNs, said he’d be hard-pressed to think of a company that isn’t at risk.
The Apache Software Foundation developed this as a second version of its widely used Java logging framework. According to the firm’s advisory, the issue can be mitigated by reconfiguring as guided or by patching to Log4j 2.15.0.
Threat actors can use the flaw to gain access to systems for the purposes of installing malware, stealing data, phishing, etc.
One of the first places to demonstrate the vulnerability was Minecraft.
Users managed to get remote code execution on MC servers after sending a simple message in the chatbox. With over 126 million players a month, there could have been a lot of damage had the flaw gone unnoticed. Moreover, it demonstrates how other more vital services are at risk.
Prompt Response, Long Cleanup
A group of top cloud hosting services, including AWS, Microsoft, Google Cloud, and IBM discovered vulnerabilities in some of their services. They are now hurrying to fix them.
Although the response has been quick by all accounts, the effects are likely to linger for years, according to Wired.
There are potential vulnerabilities at multiple points in every company. It’s likely that some companies won’t manage to catch them all. This means these exploitable openings will be around for a while.
For the time being, it will be wise to check the websites of the various vendors you use and follow their guidance on the ongoing issue.
