Inet 900 Firmware: Download of Code Without Integrity Check

Published Updated By the CyberSecBulletin desk

CVE-2022-24117 is a critical-severity download of code without integrity check vulnerability in Inet 900 Firmware from Ge, with a CVSS 3.1 base score of 9.8 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 8.3.0 as the first without the flaw, so updating Inet 900 Firmware to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.37% chance of exploitation within 30 days, which is low compared with other CVEs.

Patch this week

Critical severity: a successful attack would have severe impact.

What to do

  1. Update Inet 900 Firmware to 8.3.0 or a later version.
  2. Update Inet Ii 900 Firmware to 8.3.0 or a later version.
  3. Update Sd2 Firmware to 6.4.7 or a later version.
  4. Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description

Certain General Electric Renewable Energy products download firmware without an integrity check. This affects iNET and iNET II before 8.3.0, SD before 6.4.7, TD220X before 2.0.16, and TD220MAX before 1.2.6.

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

The underlying weakness: Download of Code Without Integrity Check

The product downloads source code or an executable from a remote location and executes the code without sufficiently verifying the origin and integrity of the code.

How developers prevent this class of flaw

  • Perform proper forward and reverse DNS lookups to detect DNS spoofing.
  • Encrypt the code with a reliable encryption scheme before transmitting.
  • Run your code using the lowest privileges that are required to accomplish the necessary tasks. If possible, create isolated accounts with limited privileges that are only used for a single task. That way, a successful attack will not immediately give the attacker access to the rest of the software or its environment. For example, database applications rarely need to run as the database administrator, especially in day-to-day operations.
