monitoring software, are affected:
o Version 00.00.01a and prior
- --------- Begin Update A part 1 of 2 ---------

4.2 VULNERABILITY OVERVIEW
4.2.1 DESERIALIZATION OF UNTRUSTED DATA CWE-502
Delta Electronics InfraSuite Device Master versions 00.00.01a and prior
deserialize user-supplied data provided through the Device-DataCollect service
port without proper verification. An attacker could provide malicious
serialized objects to execute arbitrary code upon deserialization.
CVE-2022-41778 has been assigned to this vulnerability. A CVSS v3 base score of
9.8 has been calculated; the CVSS vector string is ( AV:N/AC:L/PR:N/UI:N/S:U/
C:H/I:H/A:H ).
4.2.2 DESERIALIZATION OF UNTRUSTED DATA CWE-502
Delta Electronics InfraSuite Device Master versions 00.00.01a and prior
deserialize user-supplied data provided through the Device-Gateway service port
without proper verification. An attacker could provide malicious serialized
objects to execute arbitrary code upon deserialization.
CVE-2022-38142 has been assigned to this vulnerability. A CVSS v3 base score of
9.8 has been calculated; the CVSS vector string is ( AV:N/AC:L/PR:N/UI:N/S:U/
C:H/I:H/A:H ).
4.2.3 DESERIALIZATION OF UNTRUSTED DATA CWE-502
Delta Electronics InfraSuite Device Master versions 00.00.01a and prior
deserialize network packets without proper verification. If the device connects
to an attacker-controlled server, the attacker could send maliciously crafted
packets that would be deserialized and executed, leading to remote code
execution.
CVE-2022-41779 has been assigned to this vulnerability. A CVSS v3 base score of
8.8 has been calculated; the CVSS vector string is ( AV:N/AC:L/PR:N/UI:R/S:U/
C:H/I:H/A:H ).
4.2.4 IMPROPER LIMITATION OF A PATHNAME TO A RESTRICTED DIRECTORY ('PATH
TRAVERSAL') CWE-22
Delta Electronics InfraSuite Device Master Versions 00.00.01a and prior allow
attacker provided data already serialized into memory to be used in file
operation application programmable interfaces (APIs). This could create
arbitrary files, which could be used in API operations and could ultimately
result in remote code execution.
CVE-2022-41657 has been assigned to this vulnerability. A CVSS v3 base score of
9.8 has been calculated; the CVSS vector string is ( AV:N/AC:L/PR:N/UI:N/S:U/
C:H/I:H/A:H ).
4.2.5 IMPROPER LIMITATION OF A PATHNAME TO A RESTRICTED DIRECTORY ('PATH
TRAVERSAL') CWE-22
Delta Electronics InfraSuite Device Master Versions 00.00.01a and prior
mishandle .ZIP archives containing characters used in path traversal. This path
traversal could result in remote code execution.
CVE-2022-41772 has been assigned to this vulnerability. A CVSS v3 base score of
9.8 has been calculated; the CVSS vector string is ( AV:N/AC:L/PR:N/UI:N/S:U/
C:H/I:H/A:H ).
4.2.6 MISSING AUTHENTICATION FOR CRITICAL FUNCTION CWE-306
The database backup function in Delta Electronics InfraSuite Device Master
Versions 00.00.01a and prior lacks proper authentication. An attacker could
provide malicious serialized objects which, when deserialized, could activate
an opcode for a backup scheduling function without authentication. This
function allows the user to designate all function arguments and the file to be
executed. This could allow the attacker to start any new process and achieve
remote code execution.
CVE-2022-40202 has been assigned to this vulnerability. A CVSS v3 base score of
9.8 has been calculated; the CVSS vector string is ( AV:N/AC:L/PR:N/UI:N/S:U/
C:H/I:H/A:H ).
4.2.7 MISSING AUTHENTICATION FOR CRITICAL FUNCTION CWE-306
Delta Electronics InfraSuite Device Master versions 00.00.01a and prior lack
proper authentication for functions that create and modify user groups. An
attacker could provide malicious serialized objects that could run these
functions without authentication to create a new user and add them to the
administrator group.
CVE-2022-41688 has been assigned to this vulnerability. A CVSS v3 base score of
9.8 has been calculated; the CVSS vector string is ( AV:N/AC:L/PR:N/UI:N/S:U/
C:H/I:H/A:H ).
4.2.8 MISSING AUTHENTICATION FOR CRITICAL FUNCTION CWE-306
Delta Electronics InfraSuite Device Master versions 00.00.01a and prior lacks
authentication for a function that changes group privileges. An attacker could
use this to create a denial-of-service state or escalate their own privileges.
CVE-2022-41644 has been assigned to this vulnerability. A CVSS v3 base score of
8.8 has been calculated; the CVSS vector string is ( AV:N/AC:L/PR:L/UI:N/S:U/
C:H/I:H/A:H ).
4.2.9 MISSING AUTHENTICATION FOR CRITICAL FUNCTION CWE-306
Delta Electronics InfraSuite Device Master versions 00.00.01a and prior allow
unauthenticated users to trigger the WriteConfiguration method, which could
allow an attacker to provide new values for user configuration files such as
UserListInfo.xml. This could lead to the changing of administrative passwords.
CVE-2022-41776 has been assigned to this vulnerability. A CVSS v3 base score of
7.5 has been calculated; the CVSS vector string is ( AV:N/AC:L/PR:N/UI:N/S:U/
C:N/I:H/A:N ).
4.2.10 MISSING AUTHENTICATION FOR CRITICAL FUNCTION CWE-306
Delta Electronics InfraSuite Device Master versions 00.00.01a and prior allow
unauthenticated users to access the aprunning endpoint, which could allow an
attacker to retrieve any file from the "RunningConfigs" directory. The attacker
could then view and modify configuration files such as UserListInfo.xml, which
would allow them to see existing administrative passwords.
CVE-2022-41629 has been assigned to this vulnerability. A CVSS v3 base score of
7.5 has been calculated; the CVSS vector string is ( AV:N/AC:L/PR:N/UI:N/S:U/
C:H/I:N/A:N ).

vulnerabilities to CISA.
5. MITIGATIONS
- --------- Begin Update A part 2 of 2 ---------
Delta Electronics recommends users uninstall old versions of InfraSuite Device
Master and reinstall the updated Version 1.0.3 using the installer .
- --------- End Update A part 2 of 2 ---------
Delta Electronics also recommends users follow CISA's security recommendations.
CISA recommends users take defensive measures to minimize the risk of
exploitation of this vulnerability these vulnerabilities. Specifically, users
should:
o Minimize network exposure for all control system devices and/or systems,
and ensure they are not accessible from the Internet .
o Locate control system networks and remote devices behind firewalls and
isolate them from business networks.
o When remote access is required, use secure methods, such as Virtual Private
Networks (VPNs), recognizing VPNs may have vulnerabilities and should be
updated to the most current 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 at cisa.gov/ics . 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 .
Additional mitigation guidance and recommended practices are publicly available
on the ICS webpage at cisa.gov/ics 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.
No known public exploits specifically target these vulnerabilities.
