#Vmware horizon client log4j code
Vendor VMware has already published security advisory VMSA-2021-0028 on Apache Log4j vulnerability CVE-2021-44228 (remote code execution) as of December 10, 2021. Horizon 7 functionality is enhanced by an updated set of Horizon Clients provided with this release. This probably includes various products from VMware. US CISA warns ( see) that this is the biggest vulnerability of the year, threatening hundreds of millions of devices and programs. Since proof of concept (PoC) for the remote code execution vulnerability in log4j was published on December 9, 2021, the IT world has been upside down. If an attacker succeeds in specifying the URL to a server he controls in the log file, he can hijack a server via logging (Log4Shell). This can also include Java classes, which are then executed. If an attacker writes malicious code in the form of a URL to the log file, the JNDI directory service will then contact the LDAP server listed in the log to request data from it. The vulnerability has been assigned a CVSSv3 value of 10.0 (highest value). Cybersecurity firm SentinelOne dubbed the group. A 'potentially destructive actor' aligned with the government of Iran is actively exploiting the well-known Log4j vulnerability to infect unpatched VMware Horizon servers with ransomware. The JNDI lookup function of log4j allows variables to be retrieved via the JNDI – Java Naming and Directory Interface. Iranian Hackers Targeting VMware Horizon Log4j Flaws to Deploy Ransomware. There is a critical vulnerability in the JNDI lookup function in the Java log4j library used for logging, which could allow attackers to inject and execute remote code. NHS officials also noted signs that vulnerable organizations can look for to identify any possible attacks they may have sustained.I had already pointed out the problem on Decemin the blog post 0-day CVE-2021-44228 in Java library log4j puts many projects at risk.

They went on to provide guidance on specific steps affected organizations can take to mitigate the threat.Ĭhief among them is the recommendation to install an update that VMware released for its Horizon product, which gives organizations a means to virtualize desktop and app capabilities using the company’s virtualization technology. “An unknown threat group has been observed targeting VMware Horizon servers running versions affected by Log4Shell vulnerabilities in order to establish persistence within affected networks,” officials with the UK’s National Health System wrote.

Crossing the Log4j Horizon - A Vulnerability With No Return. In a report this week, cybersecurity firm Sophos wrote that VMware's virtual desktop and. Exploiting CVE-2021-44228 in VMWare Horizon for remote code execution and more. VMware's Horizon virtualization platform has become an ongoing target of attackers exploiting the high-profile Log4j flaw to install backdoors and cryptomining malware. From Settings > Apps & Features, uninstall VMware Horizon Connection Server and wait for it to complete. Miscreants deployed cryptominers, backdoors since late December, Sophos says. Malicious hackers quickly began actively exploiting CVE-2021-44228 to compromise sensitive systems. A reboot is not needed and should not be done.
