FKIE_CVE-2026-49392

Vulnerability from fkie_nvd - Published: 2026-08-19 17:18 - Updated: 2026-08-19 18:16
Severity
5.3 (Medium) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L
Summary
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.
