Command Centre Server: Inclusion of Functionality from Untrusted Control Sphere
CVE-2024-43690 is a high-severity inclusion of functionality from untrusted control sphere vulnerability in Command Centre Server from Gallagher, with a CVSS 3.1 base score of 8.0 out of 10. It can be exploited remotely over the network by an attacker with administrator privileges, without any action from a user. The record lists versions vEL9.10.1530(MR2), vEL9.00.2168 (MR4), vEL8.90.2155 (MR5) as the first without the flaw, so updating Command Centre Server to one of those releases or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.6% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update Command Centre Server to vEL9.10.1530(MR2) or vEL9.00.2168 (MR4) or vEL8.90.2155 (MR5) or vEL8.80.1938 (MR6), whichever matches your release line, or a later version.

Official description
Inclusion of Functionality from Untrusted Control Sphere(CWE-829) in the Command Centre Server and Workstations may allow an attacker to perform Remote Code Execution (RCE). This issue affects: Command Centre Server and Command Centre Workstations 9.10 prior to vEL9.10.1530 (MR2), 9.00 prior to vEL9.00.2168 (MR4), 8.90 prior to vEL8.90.2155 (MR5), 8.80 prior to vEL8.80.1938 (MR6), all versions of 8.70 and prior.

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.
