Summary

CVE-2024-28829 is a medium-severity Least Privilege Violation (CWE-272) vulnerability in Checkmk Checkmk. Its CVSS base score is 5.2 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked at the 8th 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-24 (Access Control Decisions) and AC-6 (Least Privilege) — see the control section below for these in your framework.

Mitigating Controls (NIST 800-53 r5) AI

AC-24 Access Control Decisions good match

Explicitly requires that every access decision be based on authoritative, protected decision data rather than caller-supplied inputs.

AC-6 Least Privilege good match

AC-6 directly requires employing least privilege so that elevated rights are granted only when needed and revoked immediately afterward.

SI-10 Information Input Validation good match

Input validation can reject malformed or attacker-controlled values before they reach a security decision point.

AC-3 Access Enforcement partial match

Access enforcement requires decisions to be made from trusted policy data rather than modifiable client-supplied inputs.

AC-4 Information Flow Enforcement partial match

Information-flow enforcement applies rules to validated, internal attributes instead of untrusted external values.

Mitigating Controls (NIST CSF 2.0) AI

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.

PR.AA-03 mostly match
prevents

Strong authentication mechanisms directly prevent security decisions from depending on modifiable, untrusted inputs.

PR.AA-04 mostly match
prevents

Verification and protection of identity assertions stops reliance on attacker-controlled values for authorization decisions.

PR.AA-05 mostly match
prevents

Directly enforces least-privilege policy and ongoing review that prevents failure to drop elevated rights after privileged operations.

PR.AA-01 partial match
prevents

Proper management of identities/credentials reduces the chance that security decisions will be driven by untrusted inputs.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.

A.8.28 Secure coding mostly match
prevents

Secure coding standards directly prohibit using untrusted inputs for security-critical decisions.

A.8.29 Security testing in development and acceptance mostly match
finds

Security testing in development catches input-validation flaws before deployment.

A.8.16 Monitoring activities partial match
finds

Monitoring can detect exploitation but does not stop the underlying weakness.

A.8.18 Use of privileged utility programs partial match
mitigates

Restricts and monitors privileged utility programs, directly addressing the need to drop elevated rights immediately after use.

A.8.2 Privileged access rights partial match
mitigates

Privileged access rights explicitly require least-privilege assignment and timely revocation after elevated operations.

A.8.26 Application security requirements partial match
prevents

Application security requirements explicitly call for validation of inputs used in security decisions.

Hardening callouts derived

Configuration rules from DISA STIG baselines that bear on weaknesses of the type cited by this CVE. Each rule is shown with the relationship its mapping actually records, against the CWE it was authored against. Derived via CVE→CWE over `controls_xwalks` (authoritative rows only; rows rated `none` are excluded).

Ubuntu 24.04 (1 rule)
  • V-270689 Ubuntu 24.04 LTS must prevent all software from executing at higher privilege levels than users executing the software and the audit system must be configured to audit the execution of privileged functions. prevents CWE-272
Windows 10 (1 rule)
  • V-220712 Only accounts responsible for the administration of a system must have Administrator rights on the system. prevents CWE-272
Windows Server 2022 (1 rule)
  • V-254428 Windows Server 2022 must only allow administrators responsible for the member server or standalone or nondomain-joined system to have Administrator rights on the system. prevents CWE-272
