CVE-2023-29158

SUBNET PowerSYSTEM Center Authentication Bypass by Capture-replay

Published Jun 19, 2023 CVSS 3.1 · 6.1 Medium EPSS < 1% KEV · Not listed
Description



SUBNET PowerSYSTEM Center versions 2020 U10 and prior are vulnerable to replay attacks which may result in a denial-of-service condition or a loss of data integrity.






Remediation

Vendor Solution

SUBNET Solutions has fixed these issues by enabling a file integrity check on uploaded images and anti-forgery tokens to prevent replay attacks. The fix was introduced in PowerSYSTEM Center update 12 as well as Update 8+Hotfix (both identified by release number 5.12.2305.10101, which can be located in Settings / Overview / Version).


Vendor Workaround

SUBNET Solutions recommends users to follow the following workarounds: * Users should verify that SVG files do not contain HTML elements or scripts and validate that JPG and PNG files are not SVG files. * Users should verify network security rules to ensure that outbound connections to the internet are not possible. * If the above cannot be performed or notifications are not required, disable email notifications for reports from PowerSYSTEM Center. * Monitor user activity and ensure application control rules only allow preauthorized executables to run. * Deny users to run other executables on client access servers (PowerSYSTEM Center front end access point).
