Release Date: December 14, 2021


Ontech is working closely with our partners and vendors to proactively address any critical vulnerability affecting products containing the Log4j software library.  Please read our notice below and understand this is a widespread vulnerability affecting various products across the industry.  As more information and updates become available, Ontech will provide additional details.

  • Ontech Systems, at this time and with the assistance and guidance of our partners, has not found any vulnerability in our managed service products from this issue that would impact clients or their data. We will continue to work diligently with our partners to address any potential risks that could arise.
  • No Ontech internal support systems have been compromised and our data continues to be backed up and protected safely and securely.
  • One known product many clients utilize is the Unifi wireless system. Our technical team will be reviewing current firmware versions and proactively reaching out to those clients affected to verify the current firmware version and update necessary systems.  Please expect a phone call and/or email to outline the process for the updates potentially needed.  Here is a link to more information found in the Unifi Community.
  • There may be other software/hardware your businesses purchase or subscribe to from other vendors, that is out of our (and your) control that may have vulnerabilities. Most reputable vendors are making immediate changes and pushing updates to address the vulnerability. If the vendor is requesting action or changes on your network, we encourage our clients to forward any notifications you receive from those vendors to your Account Team or the Ontech Support desk for further review.

For a list of affected vendors and products please review this community resource.


WASHINGTON – Cybersecurity and Infrastructure Security Agency (CISA) Director Jen Easterly released the following statement on the “log4j” vulnerability: 

“CISA is working closely with our public and private sector partners to proactively address a critical vulnerability affecting products containing the log4j software library. This vulnerability, which is being widely exploited by a growing set of threat actors, presents an urgent challenge to network defenders given its broad use. End users will be reliant on their vendors, and the vendor community must immediately identify, mitigate, and patch the wide array of products using this software.  Vendors should also be communicating with their customers to ensure end users know that their product contains this vulnerability and should prioritize software updates.

“We are taking urgent action to drive mitigation of this vulnerability and detect any associated threat activity. We have added this vulnerability to our catalog of known exploited vulnerabilities, which compels federal civilian agencies — and signals to non-federal partners — to urgently patch or remediate this vulnerability. We are proactively reaching out to entities whose networks may be vulnerable and are leveraging our scanning and intrusion detection tools to help government and industry partners identify exposure to or exploitation of the vulnerability.

“The Joint Cyber Defense Collaborative is designed to manage this kind of risk. We have established a JCDC senior leadership group to coordinate collective action and ensure shared visibility into both the prevalence of this vulnerability and threat activity. By bringing together key government and private sector partners via the JCDC, including our partners at the FBI and NSA, we will ensure that our country’s strongest capabilities are brought to bear in an integrated manner against this risk. To ensure the broadest possible dissemination of key information, we are also convening a national call with critical infrastructure stakeholders on Monday afternoon where CISA’s experts provide further insight and address questions.

“We continue to urge all organizations to review the latest CISA current activity alert and upgrade to log4j version 2.15.0, or apply their appropriate vendor recommended mitigations immediately.

“To be clear, this vulnerability poses a severe risk. We will only minimize potential impacts through collaborative efforts between government and the private sector. We urge all organizations to join us in this essential effort and take action.”

CISA recommends asset owners take three additional, immediate steps regarding this vulnerability:

  1. Enumerate any external facing devices that have log4j installed.
  2. Make sure that your security operations center is actioning every single alert on the devices that fall into the category above.
  3. Install a web application firewall (WAF) with rules that automatically update so that your SOC is able to concentrate on fewer alerts.

This effort also underscores the urgency of building software securely from the start and more widespread use of Software Bill of Materials (SBOM), both of which were directed by President Biden in his Executive Order issued in May 2021.  A SBOM would provide end users will the transparency they require to know if their products rely on vulnerable software libraries.
