CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:HSummary
CVE-2024-35177 is a high-severity Improper Access Control (CWE-284) vulnerability in Wazuh Wazuh. Its CVSS base score is 7.8 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 18th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
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.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2024-35177 is a local privilege escalation vulnerability in the Wazuh-agent for Windows, part of the open-source Wazuh platform for threat prevention, detection, and response across various environments. The issue stems from improper access control lists (ACLs) applied to the agent's non-default installation directory, such as C:\wazuh. This flaw, rated at CVSS 3.1 score of 7.8 (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H) and mapped to CWE-284, allows unauthorized modification of files in the installation folder because many DLLs are loaded from there without sufficient protections.
A low-privileged local user can exploit this vulnerability by placing a malicious DLL in the installation directory—one that exports the functions of a legitimate DLL not present on the system, such as rsync.dll—or by replacing the service executable binary itself. Successful exploitation leads to code execution under the context of NT AUTHORITY\SYSTEM, enabling full compromise of the host with high confidentiality, integrity, and availability impacts.
The Wazuh security advisory (GHSA-pmr2-2r83-h3cv) confirms the issue has been addressed in Wazuh-agent version 4.9.0, urging all users to upgrade immediately. No workarounds are available.

more
due to improper ACL of the non-default installation directory. A local malicious user could potentially exploit this vulnerability by placing one of the many DLL that are loaded and not present on the system in the installation folder of the agent OR by replacing the service executable binary itself with a malicious one. The root cause is an improper ACL applied on the installation folder when a non-default installation path is specified (e.g,: C:\wazuh). Many DLLs are loaded from the installation folder and by creating a malicious DLLs that exports the functions of a legit one (and that is not found on the system where the agent is installed, such as rsync.dll) it is possible to escalate privileges from a low-privileged user and obtain code execution under the context of NT AUTHORITY\SYSTEM. This issue has been addressed in version 4.9.0 and all users are advised to upgrade. There are no known workarounds for this vulnerability.

Mitigating Controls (NIST 800-53 r5) AI
Directly enforces approved authorizations for logical access, stopping unauthorized actors from reaching resources.
Enforces flow-control policies that restrict information movement between subjects and objects.
Documents duties and assigns access so that no single account can bypass intended restrictions.
Limits each account to the minimum privileges needed, reducing the chance of unauthorized access.
Defines account types, assigns/removes access, and reviews accounts to ensure only authorized actors can reach resources.
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-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.
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.
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).
PR.AA-01 supplies managed identities/credentials that support but do not implement access-control decisions, so it only partially prevents CWE-284 in either direction.
Authentication directly blocks unauthenticated actors (partial prevention of CWE-284) but leaves authorization logic, policy enforcement, and role checks untouched, so the control neither eliminates nor fully mitigates the broader weakness.
PR.DS-01 encryption mitigates impact of failed access checks on stored data but neither implements nor constrains access-control logic itself.
Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI
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.
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.
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.
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.
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.
By explicitly transferring security roles and responsibilities when personnel change jobs or leave, the control reduces the chance that former employees retain access rights they no longer need, thereby limiting improper access control.
Physical entry controls enforce explicit authorization and authentication at every access point, directly stopping unauthorized actors from reaching information-processing assets.
