SEPCOS Control and Protection Relay firmware…: Insufficiently Protected Credentials

CVE-2022-2103 is a critical-severity insufficiently protected credentials vulnerability in SEPCOS Control and Protection Relay firmware package from Secheron, with a CVSS 3.1 base score of 9.1 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists version 1.23.21 as the first without the flaw, so updating SEPCOS Control and Protection Relay firmware package to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 1.09% chance of exploitation within 30 days, higher than 66% of scored CVEs.

Patch this week

Critical severity: a successful attack would have severe impact.

What to do

  1. Update SEPCOS Control and Protection Relay firmware package to 1.23.21 or a later version.
  2. Update Sepcos Control And Protection Relay Firmware to 1.23.21 or 1.24.8 or 1.25.3, whichever matches your release line, or a later version.
  3. Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description

An attacker with weak credentials could access the TCP port via an open FTP port, allowing an attacker to read sensitive files and write to remotely executable directories.

Source: the CVE record as published by its numbering authority, via NVD and CVE.org.

The underlying weakness: Insufficiently Protected Credentials

The product transmits or stores authentication credentials, but it uses an insecure method that is susceptible to unauthorized interception and/or retrieval.

How developers prevent this class of flaw

  • Use an appropriate security mechanism to protect the credentials.
  • Make appropriate use of cryptography to protect the credentials.
  • Use industry standards to protect the credentials (e.g. LDAP, keystore, etc.).
