CVSS v3 7.8
ATTENTION: Exploitable remotely/low attack complexity
Vendor: Siemens
Equipment: SINEC NMS
Vulnerabilities: Incorrect Permission Assignment for Critical Resource, Improper Neutralization of Input During Web Page Generation (‘Cross-site Scripting’)

2. RISK EVALUATION

Successful exploitation of these vulnerabilities could allow an authenticated local attacker to inject arbitrary code and escalate privileges or a remote attacker to perform a stored cross-site scripting(XSS) attack that may lead to unintentional modification of application data by legitimate users.

3. TECHNICAL DETAILS

Sina Kheirkhah (@SinSinology) of Summoning Team (@SummoningTeam) working with Trend Micro Zero Day Initiative reported these vulnerabilities to Schneider Electric and CISA.

4. MITIGATIONS

Schneider Electric provided version 16.0.0.23212 of Update Service to address these vulnerabilities.

The update is available for download through IGSS Master > Update IGSS Software or from the Schneider Electric support page.

If users choose not to apply the remediation provided above, they should immediately apply the following mitigations to reduce the risk of exploit:

Disable the IGSS Update Service as an Administrator, and only enable it while installing new updates.
Review and implement the security guideline for IGSS on securing an IGSS SCADAinstallation.
Follow the general security recommendation below and verify that devices are isolated on a private network and firewalls are configured with strict boundaries for devices that require remote access.

For more information, see Schneider Electric security notification SEVD-2023-255-01.

Schneider Electric recommends the following industry cybersecurity best practices:

Locate control and safety system networks and remote devices behind firewalls and isolate them from the business network.
Install physical controls so no unauthorized personnel can access your industrial control and safety systems, components, peripheral equipment, and networks.
Place all controllers in locked cabinets and never leave them in the “Program” mode.
Never connect programming software to any network other than the network intended for that device.
Scan all methods of mobile data exchange with the isolated network such as CDs, USB drives, etc. before use in the terminals or any node connected to these networks.
Never allow mobile devices that have connected to any network besides the intended network to connect to the safety or control networks without proper sanitation.
Minimize network exposure for all control system devices and systems and ensure that they are not accessible from the internet.
When remote access is required, use secure methods, such as virtual private networks (VPNs). Recognize that VPNs may have vulnerabilities and should be updated to the most current version available. Also, understand that VPNs are only as secure as the connected devices.

CISA recommends users take defensive measures to minimize the risk of exploitation of these vulnerabilities. CISA reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures.
