VMWARE HORIZON HACKERS SERVERS UNDER EXPLOIT UPDATE

VMware has advised Horizon users to update to new versions of the software with patches for the Log4Shell vulnerabilities. Huntress says "that ~34% of the 180 Horizon servers (62) we analyzed were unpatched and internet-facing at the time of this publication." It also notes that the Shodan search tool lists roughly 25,000 internet-facing Horizon servers. Plenty of people will have some pondering to do. "For those of you just learning about the mass exploitation of VMware Horizon servers and the installation of backdoor web shells," Huntress says, "you should seriously consider the possibility that your server is compromised if it was unpatched and internet-facing." The former can offer attackers initial access to a network the latter can help them maintain that access so they can gather more information, compromise additional machines, and potentially evade detection. Others, including The DFIR Report and Red Canary, reported similar activity that day.Įxploiting the Log4Shell vulnerabilities to deploy Cobalt Strike makes sense. Huntress says that "an unrelated Managed Antivirus detection (Microsoft Defender) tipped our ThreatOps team to new exploitation of the Log4Shell vulnerability in VMware Horizon" on Jan.

(Among other things.) But hackers often use cracked versions of the software to conduct attacks, too. The open source extensible framework figures into VMware’s Horizon Desktop as-a-Service Platform, vCenter Server, Operations Manager, and Hyperic Server.Cobalt Strike, meanwhile, is a command and control framework security professionals use to assess an organization's ability to respond to malicious activity on its network.

The company, just two weeks ago, released an update for several of its products to resolve a publicized remote code execution vulnerability in Apache Struts 2. It’s the fifth time this month that VMware has pushed out patches for its customers and the second time this month its pushed out an update for Workstation and Fusion. Ijzerman says the company is encouraging its customers to expedite updating but stresses that “emergency measures like taking environments offline are not called for.” The patches took about two weeks to deploy because the company knew the vulnerabilities affected Workstation but were unsure how they affected ESXi and Fusion. The company knew going into the competition that Workstation was a target and acknowledged during the contest that its researchers were investigating the issues after receiving details around them from ZDI, 360 Security, and Team Sniper. VMware was transparent about the vulnerabilities after they popped up at Pwn2Own. All of vulnerabilities, as the teams demonstrated, could have allowed a guest to execute code on the host. A similar uninitialized memory usage vulnerability (CVE-2017-4905) could have led to an information leak on ESXi, Workstation, and Fusion. The issue that Team Sniper managed to exploit was an uninitialized memory usage vulnerability (CVE-2017-4904) in ESXi, Workstation, and Fusion XHCI.

The Zero Day Initiative and Trend Micro, Pwn2Own sponsors, upped the reward for an escape from $75,000 to $100,000 this year after no one targeted Workstation in 2016.Īccording to a security advisory posted by VMware, 360 Security technically exploited a heap buffer overflow (CVE-2017-4902) and uninitialized stack memory usage vulnerability (CVE-2017-4903) in SVGA, a virtual graphics driver in the hypervisor. It was the first time one team, let alone two, was able to successfully exploit the platform. The teams collectively earned $205,000 for their exploits.

Team Sniper, comprised of hackers from China’s Keen Lab and PC Manager, used a Windows kernel bug and two VMware bugs–an info leak and an uninitialized buffer–to go guest-to-host on their machine. Mj011sec, a hacker with 360 Security, chained together a type confusion bug in Edge, a Windows kernel bug and an uninitialized buffer in VMware for his exploit, a complete virtual machine escape. Two groups, Qihoo’s 360 Security and Tencent Security’s Team Sniper, used the bugs to exploit the company’s Workstation hypervisor on the last day of the hacking challenge, two weeks ago, in Vancouver. Monty Ijzerman, manager of the company’s Security Response Center, confirmed that VMware had pushed patches for the bugs, critical and moderate issues in its ESXi, VMware Workstation, and VMware Fusion products. The flaws enabled an attacker to execute code on a workstation and carry out a virtual machine escape to attack a host server. VMware on Tuesday patched a series of vulnerabilities uncovered earlier this month at Pwn2Own.
