Inet 900 Firmware: Inclusion of Functionality from Untrusted Control Sphere
CVE-2022-24119 is a critical-severity inclusion of functionality from untrusted control sphere 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 0.77% chance of exploitation within 30 days, higher than 56% of scored CVEs.
Critical severity: a successful attack would have severe impact.
What to do
- Update Inet 900 Firmware to 8.3.0 or a later version.
- Update Inet Ii 900 Firmware to 8.3.0 or a later version.
- Update Sd2 Firmware to 6.4.7 or a later version.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

The underlying weakness: Inclusion of Functionality from Untrusted Control Sphere
The product imports, requires, or includes executable functionality (such as a library) from a source that is outside of the intended control sphere.
How developers prevent this class of flaw
- Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
- When the set of acceptable objects, such as filenames or URLs, is limited or known, create a mapping from a set of fixed input values (such as numeric IDs) to the actual filenames or URLs, and reject all other inputs. For example, ID 1 could map to inbox.txt and ID 2 could map to profile.txt. Features such as the ESAPI AccessReferenceMap provide this capability.
- For any security checks that are performed on the client side, ensure that these checks are duplicated on the server side, in order to avoid CWE-602. Attackers can bypass the client-side checks by modifying values after the checks have been performed, or by changing the client to remove the client-side checks entirely. Then, these modified values would be submitted to the server.
