Summary
Industrial Edge Management contains an authorization bypass vulnerability that
could be exploited by an unauthenticated remote attacker to circumvent
authentication and to access connected Industrial Edge Devices through the
remote connection feature. Siemens has released new versions for the affected
products and recommends to update to the latest versions.
The following versions of Siemens Industrial Edge Management are affected:
o Industrial Edge Management Pro V1 vers:intdot/>=1.7.6|<1.15.17
(CVE-2026-33892)
o Industrial Edge Management Pro V2 vers:intdot/>=2.0.0|<2.1.1
(CVE-2026-33892)
o Industrial Edge Management Virtual vers:intdot/>=2.2.0|<2.8.0

Vulnerabilities
Expand All +
CVE-2026-33892
Affected management systems do not properly enforce user authentication on
remote connections to devices. This could facilitate an unauthenticated remote
attacker to circumvent authentication and impersonate a legitimate user.
Successful exploitation requires that the attacker has identified the header
and port used for remote connections to devices and that the remote connection
feature is enabled for the device. Exploitation allows the attacker to tunnel
to the device. Security features on this device itself (e.g. app specific
authentication) are not affected.

General Recommendations
As a general security measure, Siemens strongly recommends to protect network
access to devices with appropriate mechanisms. In order to operate the devices
in a protected IT environment, Siemens recommends to configure the environment
according to Siemens' operational guidelines for Industrial Security (Download:
https://www.siemens.com/cert/operational-guidelines-industrial-security), and
to follow the recommendations in the product manuals. Additional information on

Recommended Practices
CISA recommends users take defensive measures to minimize the exploitation risk
of these vulnerabilities.
Minimize network exposure for all control system devices and/or systems, and
ensure they are not accessible from the internet.
Locate control system networks and remote devices behind firewalls and isolate
them from business networks.
When remote access is required, use more secure methods, such as Virtual
Private Networks (VPNs), recognizing VPNs may have vulnerabilities and should
be updated to the most recent version available. Also recognize VPN is only as
secure as its connected devices.
CISA reminds organizations to perform proper impact analysis and risk
assessment prior to deploying defensive measures.
CISA also provides a section for control systems security recommended practices
on the ICS webpage on cisa.gov. Several CISA products detailing cyber defense
best practices are available for reading and download, including Improving
Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies.
CISA encourages organizations to implement recommended cybersecurity strategies
for proactive defense of ICS assets. Additional mitigation guidance and
recommended practices are publicly available on the ICS webpage at cisa.gov in
the technical information paper, ICS-TIP-12-146-01B--Targeted Cyber Intrusion
Detection and Mitigation Strategies.
Organizations observing suspected malicious activity should follow established
internal procedures and report findings to CISA for tracking and correlation
against other incidents.
