Kwetsbaarheden verholpen in Zabbix

Published Dec 2, 2024 · Updated Dec 2, 2024 · nl

Vendor: Zabbix Product: Frontend Product: Zabbix

Summary

Zabbix heeft kwetsbaarheden verholpen in de Zabbix server en frontend.

Details

Interpretaties
De kwetsbaarheden omvatten een stack buffer overflow in de zbx_snmp_cache_handle_engineid functie, die kan leiden tot het uitvoeren van willekeurige code of een denial of service. Daarnaast is er een SQL-injectie kwetsbaarheid die niet-beheerders met API-toegang in staat stelt om ongeautoriseerde toegang tot gevoelige gegevens te verkrijgen. Ook zijn er kwetsbaarheden gerapporteerd die kunnen leiden tot gegevensvervalsing in de gebruikersinterface en een kleine geheugenlek die gevoelige informatie kan blootstellen.

Oplossingen
Zabbix heeft updates uitgebracht om de kwetsbaarheden te verhelpen. Zie bijgevoegde referenties voor meer informatie.
