Summary

CVE-2024-29837 is a high-severity Improper Access Control (CWE-284) vulnerability in Cs-Technologies Evolution. Its CVSS base score is 8.8 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Brute Force (T1110); ranked at the 41th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to AC-3 (Access Enforcement) and AC-4 (Information Flow Enforcement) — see the control section below for these in your framework.

Mitigating Controls (NIST 800-53 r5) AI

AC-3 Access Enforcement good match

Directly enforces approved authorizations for logical access, stopping unauthorized actors from reaching resources.

IA-12 Identity Proofing good match

Requires identity proofing at appropriate assurance levels before granting accounts, directly addressing insufficient proof of identity.

IA-2 Identification and Authentication (Organizational Users) good match

Requires unique identification and authentication of users, directly stopping weak mechanisms from being used.

IA-3 Device Identification and Authentication good match

Requires device identification and authentication before establishing connections.

IA-8 Identification and Authentication (Non-organizational Users) good match

Extends strong identification and authentication requirements to non-organizational users.

AC-4 Information Flow Enforcement good match

Enforces flow-control policies that restrict information movement between subjects and objects.

PR.AA-03 full match
prevents

Explicitly requires authentication of users/services/hardware with MFA and password-strength controls.

PR.AA-02 mostly match
prevents

Identity proofing and binding is a core prerequisite for non-weak authentication.

PR.AA-04 mostly match
prevents

PR.AA-04 directly enables verification of identity assertions (mostly preventing CWE-287 in that scope) yet leaves many other authentication failure modes unaddressed (only partial prevention overall).

PR.AA-05 mostly match
prevents

PR.AA-05 directly enforces policy-based access management and least privilege, eliminating most improper-access-control defects, yet CWE-284 also covers implementation flaws and design gaps outside a single management control.

PR.PS-01 mostly match
prevents

Hardened baselines and deviation monitoring directly eliminate most configuration-induced access-control defects, yet CWE-284 also encompasses code-level and design flaws outside the scope of configuration management alone.

PR.PS-06 mostly match
prevents

Secure SDLC practices catch most access-control defects during design/coding/testing (mostly), yet leave residual risk from runtime configuration, architecture, and operational controls (partial).

A.5.15 Access control full match
prevents

Defining and enforcing explicit access rights and restrictions for each entity directly stops the assignment of permissions that exceed what is required, eliminating the root condition that allows improper access control.

A.5.18 Access rights full match
prevents

Formal authorization, role-based provisioning, and timely revocation of access rights directly stop the creation of accounts or permissions that exceed what the business actually needs.

A.8.3 Information access restriction full match
prevents

By enforcing explicit rules on which identities or groups may perform read, write, delete or execute operations and by denying anonymous access to sensitive data, the control directly stops the creation of overly permissive or missing access-control checks.

A.8.5 Secure authentication full match
prevents

Mandating multi-factor and non-password authentication techniques counters the use of inherently weak single-factor or password-only authentication mechanisms.

A.5.16 Identity management mostly match
prevents

Requiring one-to-one mapping of identities to entities and timely removal of unused identities directly stops attackers from leveraging stale or shared accounts to bypass access restrictions.

A.5.17 Authentication information mostly match
prevents

Verifying user identity before issuing replacement credentials and forcing changes after compromise reduces the likelihood that authentication bypass can be achieved through stolen or weak credentials.
