Rockwell Automation ISaGRAF Runtime Versions 4.x and 5.x stores the password in plaintext in a file that is in the same directory as the executable file. ISaGRAF Runtime reads the file and saves the data in a variable without any additional modification. A local, unauthenticated attacker could compromise the user passwords, resulting in information disclosure.
This plugin only works with Tenable.ot.

"The following text was originally created by the Cybersecurity and Infrastructure Security Agency (CISA). The original
can be found at CISA.gov.
Rockwell Automation recommends users update to ISaGRAF Runtime 5 Version 5.72.00. End users are encouraged to restrict
or block access on TCP 1131 and TCP 1132 from outside the industrial control system. Confirm the least-privilege user
principle is followed and user/service account access to Runtime's folder location is granted with a minimum amount of
rights needed.
Rockwell Automation recommends users of affected versions evaluate the mitigations provided and apply the appropriate
mitigations to deployed products. Users are encouraged to combine this guidance with the general security guidelines for
a comprehensive defense-in-depth strategy.
To reduce risk, Rockwell Automation recommends users:
- Employ proper network segmentation and security controls.
- Minimize network exposure for all control system devices.
- Locate control systems behind firewalls.
- Isolate control systems from other networks when possible.
- Refer to the Converged Plantwide Ethernet (CPwE) Design and Implementation Guide for best practices deploying network
segmentation and broader defense-in-depth strategies.
- Consider using proper network infrastructure controls, such as firewalls, UTM devices, VPN, or other security
appliances.
- Ensure the least-privilege user principle is followed, and user/service account access to RuntimeΓ’ΒΒs folder location is
granted with a minimum amount of rights, as needed.
Please see publications from Rockwell Automation and Schneider Electric, Xylem, or contact GE for further information
about how to mitigate these vulnerabilities in additional affected products.");
