A ready-made, low-complexity path to pwning the popular enterprise VPN clients for remote workers is now circulating in the wild.

A security researcher has dropped a proof-of-concept (POC) exploit for a just-patched, high-severity security vulnerability in Cisco's client software for remote workers looking to connect to VPNs.

The bug (CVE-2023-20178) is an arbitrary file delete vulnerability in the Cisco AnyConnect Secure Mobility Client Software for Windows and Cisco Secure Client Software for Windows, which could allow authenticated attackers to escalate privileges to SYSTEM level with no user interaction.

As Cisco explained in its patch advisory earlier this month: "A vulnerability in the client update process of could allow a low-privileged, authenticated, local attacker to elevate privileges to those of SYSTEM. The client update process is executed after a successful VPN connection is established."

Security researcher Filip Dragović released an exploit that does just that via a public GitHub posting this week. It uses a process called "vpndownloader.exe," which is started in background when a user connects to a VPN using either the Cisco Secure or AnyConnect software.

"It will create directory in c:\\windows\\temp with default permissions," explained Dragović, who originally discovered the flaw and reported it to Cisco. "After creating this directory, vpndownloader.exe will check if that directory is empty, and if it's not, it will delete all files/directories in there. This behavior can be abused to perform arbitrary file delete as NT Authority\\SYSTEM account."

After that, cyberattackers can employ a known tactic to create a SYSTEM shell for abusing Windows Installer behavior and elevating privileges, he added.

Organizations should patch their clients immediately — while Cisco noted no known exploitation at the time of patching, that will likely quickly change with a PoC circulating in the wild. Successful exploitation is "noncomplex," according to the researcher, and the software has a history of being targeted by cyberattackers looking to take over data-rich VPN sessions.

Patch Now: Cisco AnyConnect Bug Exploit Released in the Wild

Livebook is a web application for writing interactive and collaborative code notebooks. On Windows, it is possible to open a `livebook://` link from a browser which opens Livebook Desktop and triggers arbitrary code execution on victim's machine. Any user using Livebook Desktop on Windows is potentially vulnerable to arbitrary code execution when they expect Livebook to be opened from browser. This vulnerability has been fixed in version 0.8.2 and 0.9.3.

From hardening Windows systems to adding access control and segmenting the network, there are steps organizations can take to better secure corporate data.

Having been in the cybersecurity industry since the early '90s, I've witnessed its transformation over many years. Today, my team conducts extensive research and testing to uncover vulnerabilities that organizations often overlook. We've successfully breached the networks of major companies in North America and identified security gaps that could have led to catastrophic consequences if left unmitigated.

In this article, I will share the top three tips that every organization must implement to secure their data and protect themselves from potential attacks based on our daily assessments and discoveries.

**1\. If Your Network Isn't Segmented, It's Not Secure**

Cybersecurity experts preach the benefits of network segmentation, but according to data cited by CIO, only 25% of organizations implement it. If you don't have a logical separation between your most critical information and your everyday employees, you're going to have a hard time securing your network.

To secure corporate data, organizations need to have configurations in place on any floor and office space that touches network ports. Doing so will prevent someone from accessing the network from any device. Even seemingly harmless devices such as printers can pose a threat to a network. During a physical penetration test we were asked to conduct for a large airline, the consultant was able to gain physical access to the airline's internal network via a printer at the gate, all without encountering any employee intervention.

To prevent unauthorized access, it's vital to implement access controls such as passwords or user authentication, as well as keeping firmware up to date to address any known vulnerabilities. And if the corporate backup solution is easily accessible to you, then it's easily accessible to threat actors who can delete the backups and detonate ransomware. In the airline example, network segmentation would isolate printers from other parts of the network to limit the potential impact of a security breach. 

Firewall access controls should be established between internal network segments to limit access to network resources in the event of an attack. Physical or logical access control should also be implemented to prevent unauthorized physical access to devices.

So, keep your devices in check (and your printers) and your network will thank you for it.

**2\. Modernize Your Network as Much as You Can Afford**

Over the past 30 years, Microsoft has made significant strides in the security of Windows and Windows networking. However, the Windows operating system still supports out-of-the-box legacy solutions that go back to Windows 95 — if not further, to Windows for Workgroups. If you've invested in modern operating systems such as Windows 10 or 11, or Windows Server 2016 or newer, there is no reason to continue to support these legacy solutions. By enabling "native mode domain," you can disable all the backward compatibility that may be weakening your network security and immediately enhance the security of your network. 

Companies can better reduce their security risks by eliminating their reliance on "end of life" solutions. Invest in upgrading legacy systems and ensure that all system software is patched through a vulnerability management and remediation program.

**3\. Greater Visibility Into Threat Vectors Through Content Filtering **

To improve your firewall's visibility into traffic leaving your environment, ensure that you have content visibility to block potential threats. The first question to ask is whether your employees are on the corporate network. A work-from-home culture may not scale well for you. However, there's no reason for your server systems to have unrestricted access to the Internet. Leveraging solutions such as content filtering can help you control the type of sites that could be accessed while an attacker is attempting to exploit your organization. For instance, blocking access to Mega.io and other common file-sharing sites used by ransomware threat actors is effective in stopping data exfiltration.

For employees in a work-from-home culture, content-filtering options such as Zscaler or even DNS monitoring solutions such as Umbrella from Cisco are useful not only for controlling the type of websites that corporate devices can access from outside of the building, but also for providing monitoring capabilities in case an employee falls victim to a phishing attack. Corporate assets should still be under the control of the organization, even if they're being used outside the traditional office environment.

Companies can no longer afford to take their eye off the ball when it comes to security measures — even basic protections such as firewalls are only minimally effective at intervening in today's potential threat levels. I cannot stress enough the importance of implementing these three things to be a step ahead of attackers and have visibility into your entire environment.
