In the past two weeks, Log4j has continued to drive security news, with more vulnerable platforms being found, and additional CVEs coming out. First up is work done by TrendMicro, looking at electric vehicles and chargers. They found a log4j attack in one of the published charger frameworks, and also managed to observe evidence of vulnerability in the Tesla In-Vehicle Infotainment system. It isn’t a stretch to imagine a piece of malware that could run on both a charger, and an EV. And since those systems talk to each other, they could spread the virus through cars moving from charger to charger.
Log4j is now up to 2.17.1, as there is yet another RCE to fix, CVE-2021-44832. This one is only scored a 6.6 on the CVSS scale, as opposed to the original, which weighed in at a 10. 44832 requires the attacker to first exert control over the Log4j configuration, making exploitation much more difficult. This string of follow-on vulnerabilities demonstrates a well-known pattern, where a high profile vulnerability attracts the attention of researchers, who find other problems in the same code.
There are now reports of Log4j being used in Conti ransomware campaigns. Additionally, a Marai-based worm has been observed. This self-propagating attack seems to be targeting Tomcat servers, among others.
