Wazuh Buffer Overflow Vulnerabilities
2026-03-17
Stack-based buffer overflow in Wazuh 4.4.0 through 4.14.2 allows authenticated remote attackers with high privileges to trigger an integer underflow in the database synchronization module, causing denial of service or potential code execution. The vulnerability exists in SQL query construction logic within wdb_delta_event.c where improper size calculations on buffers exceeding 2048 bytes can corrupt the stack. A patch is available in version 4.14.3.
Stack-based buffer overflow in Wazuh manager versions 3.9.0 through 4.14.3 allows remote attackers with high privileges to crash the `wazuh-analysisd` service via malformed JSON events, resulting in denial of service. The vulnerability stems from unsafe use of sprintf with floating-point format specifiers in the Security Configuration Assessment decoder, and may potentially enable remote code execution on affected Wazuh installations.
