Similarly, the update only fixes the security loophole but hardly reverses the damage and possible backdoors introduced on affected servers. All users since version 2.10.0 when the setting was introduced are vulnerable because the system set the flag to false by default. Users who cannot update can set the log4j2.formatMsgNoLookups to true, the same walkaround implemented by Apache’s update. Those who update their Log4j version but reset the flag to false remain vulnerable to attacks. During this delay window, vulnerable servers could come under attack from threat actors scouring the internet for vulnerable systems. It’s absolutely brutal.” Fixes released for zero-day vulnerabilityĪlthough Apache released security fixes through the Log4j 2.15.0 update on December 9, 2021, it could take a while before the updates propagated downstream. Make no mistake, this is the largest Java vulnerability we have seen in years. “This zero-day exploit impacts any application using Log4j and allows attackers to run malicious code and commands on other systems. “Any Java application that logs data uses Log4j and is the most popular logging framework in the Java ecosystem and is used by millions of applications,” said Dabirsiaghi. Screenshots of popular platforms trying to connect to external domains when under attack simulation were published on GitHub.Īccording to Arshan Dabirsiaghi, co-founder and Chief Scientist at Contrast Security, this was among the largest Java zero-day vulnerabilities discovered in years. LunaSec security team also confirmed that Apple iCloud and the gaming platform Steam suffer from the easy to exploit zero-day vulnerability. Organizations potentially vulnerable to Log4Shell attacks include Apple, Amazon, Twitter, Cloudflare, Steam, Tencent, Baidu, DIDI, JD, and NetEase, among others. “This is a case study in why the software bill of material (SBOM) concepts are so important to understand exposure.” “The Log4j vulnerability is a significant threat for exploitation due to the widespread inclusion in software frameworks, even NSA’s GHIDRA,” Joyce said. The director of cybersecurity at the National Security Agency (NSA), Rob Joyce, also confirmed that the agency’s reverse-engineering tool GHIDRA contained the vulnerable Log4j library. Similarly, ElasticSearch, Elastic Logstash use the library in various capacities. Several enterprise frameworks like Apache Struts2, Apache Solr, Apache Kafka, Apache Druid, and Apache Flink bundle Log4j by default, and their products are potentially affected by the Log4Shell zero-day vulnerability. ![]() LunaSec warns that the effect of compromise could be severe given the vulnerability’s ease of exploitation and the library’s ubiquitous nature. However, many owners were still unaware that they were affected by the zero-day vulnerability and could unknowingly come under attack. Experts warn that large numbers of vulnerable servers could soon come under attack, and the vulnerability could trigger a “mini-internet meltdown.” Scores of servers could soon come under attack via Log4j zero-day vulnerabilityĭeutsche Telekom Group’s Cyber Emergency Response Team (CERT) said its honeypots came under attack from threat actors attempting to exploit the vulnerability. Similarly, CERT New Zealand, Bad Packets, and GreyNoise said they had detected mass scanning activities targeting vulnerable servers.
