DW VMAX Security Bulletin

-----------------------------------

Dear DW Partners and Customers,

At Digital Watchdog, the security of your systems and the trust you place in our products are our highest priorities. We are writing to tell you about a security issue we identified on certain VMAX systems running a previous firmware version.

What We've Found

Some affected units may beep continuously and stop responding. Our investigation indicates these malfunctions may be linked to malware or unauthorized access.

Affected Models

System	Affected Firmware
VMAX IP G4	1.5.6.1. or earlier
VMAX IP Plus	1.5.6.1 or earlier
VMAX IP G4N	1.6.0.16 or earlier
VMAX A1 G4	1.0.1.67 or earlier
VMAX A1 Plus	1.0.13.11 or earlier

Known Issue Notice

A potential XSS vulnerability has been brough forward for VMAX recorders that use older versions of jQuery.

This potential security concern has been noted in the past and developers have already implemented defenses against the relevant vulnerabilities. As a result, even though older jQuery components are still present, there are currently no exposed vectors through which an attacker could directly execute malicious scripts.

Developers are actively developing a new web interface that removes jQuery dependency completely and is currently undergoing testing.

What We Are Doing

We take every potential security issue seriously and are acting quickly to protect your installations.

If your VMAX unit shows these symptoms, contact us and we will replace it right away.

What You Should Do

Check your system model and firmware version against the table above.
If your unit is beeping continuously or not responding, contact DW Technical Support at [phone / email] to arrange a replacement.
If your unit is on an affected firmware version but working normally, [update to the latest firmware / follow the steps at link] as soon as possible.
After upgrading the firmware, change the ADMIN password immediately. Do not reuse the previous password.

We're sorry for any disruption this causes and thank you for your continued partnership. Our support team is ready to help with any questions.
