Evidence used

  • No CISA KEV confirmation is currently recorded.
  • A structured source references public exploit or proof-of-concept material.
  • Exploitation requires an existing local or physical foothold with privileges.
  • EPSS is 0.30% for the current model date.

Compensating controls

  • Validate the affected product branch and deploy the verified fixed release.
  • Restrict local access and enforce least privilege on affected hosts.
  • Increase monitoring for the attack path and post-exploitation behaviour described in the report.

Verification

  1. Confirm that the asset runs wazuh wazuh and falls inside the recorded affected range.
  2. Verify the installed build against the product-specific fixed version after deployment.
  3. Validate exposure, authentication requirements and compensating controls in the actual environment.
  4. Reopen this reassessment when CVSS, KEV, EPSS, exploit evidence or remediation changes.
Mitigation target: As exposure requiresRemediation target: Within 365 days

This automated reassessment organises public evidence. It does not know asset exposure, business impact or control effectiveness and does not replace CVSS or a human risk decision.

No EUVD known-exploited evidence

Wazuh is a free and open source platform used for threat prevention, detection, and response. From 4.6.0 until 4.14.6 and 5.0.0-beta3, DB::getFile() and DB::searchFile() in src/syscheckd/src/db/src/file.cpp concatenate a monitored file path into SQLite row filters. On non-Windows systems, FIMDBCreator::encodeString() does not escape the value. A local user who can create a filename in a File Integrity Monitoring directory can inject a UNION SELECT expression when wazuh-syscheckd processes or deletes that path. The confirmed primitive manipulates SELECT result sets consumed by the FIM code; stacked statements and remote code execution were not demonstrated. This issue is fixed in versions 4.14.6 and 5.0.0-beta3.

Why

The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly.

How

An attacker operating through local access may attempt exploitation with low privileges. If successful, the issue may execute code or commands in the affected security context.

Exploit reality and attack path

CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.

Observed exploitation
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
No confirmed evidence

No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.

Public PoC / exploit material
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
Reference recorded

A structured CVE source labels at least one public reference as exploit material. BlackTree has not independently validated that it is safe, reliable or weaponised.

CWE-20 ↗

CWE-20: Improper Input Validation. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly.

?CVSS means Common Vulnerability Scoring System. The vector records the metric values used to calculate technical severity.

Common Vulnerability Scoring System 3.1: the compact vector below is decoded into plain language.

AVLocalAttack vector: The attacker needs local access to the vulnerable system.ACLowAttack complexity: No specialised conditions are required beyond attacker-controlled input.PRLowPrivileges required: The attacker needs basic user-level privileges.UINoneUser interaction: No action by another user is required.SUnchangedScope: The security impact remains within the vulnerable component's authority.CLowConfidentiality impact: A successful attack can cause a limited loss.ILowIntegrity impact: A successful attack can cause a limited loss.ALowAvailability impact: A successful attack can cause a limited loss.
Post-exploitation / living off the land
After compromise, an attacker may use built-in shells, scripting engines, scheduled tasks and native network utilities for discovery, persistence or movement. This is a plausible LoTL path, not evidence that it has occurred for every attack.

Official advisory ↗
JVN iPedia · Japanese · JVNDB-2026-033651Wazuh Inc.のWazuhにおける複数の脆弱性

Wazuhは、脅威の予防、検出、および対応に使用される無料かつオープンソースのプラットフォームです。バージョン4.6.0から4.14.6および5.0.0-beta3までの間、src/syscheckd/src/db/src/file.cpp内のDB::getFile()およびDB::searchFile()は、監視対象ファイルのパスをSQLiteの行フィルターに連結しています。非Windowsシステムにおいて、FIMDBCreator::encodeString()は値をエスケープしません。ローカルユーザーがファイルインテグリティモニタリング（FIM）ディレクトリ内にファイル名を作成できる場合、wazuh-syscheckdはそのパスを処理または削除する際にUNION SELECT式を注入できる可能性があります。確認されたプリミティブは、FIMコードが利用するSELECTの結果セットを操作するものであり、複数ステートメントの連結やリモートコード実行は確認されていません。この問題はバージョン4.14.6および5.0.0-beta3で修正されています。
