The zbx_get_next_field function in libs/zbxcommon/str.c in Zabbix Server before 1.6.8 allows remote attackers to cause a denial of service (crash) via a request that lacks expected separators, which triggers a NULL pointer dereference, as demonstrated using the Command keyword.

Security readout for executives and security teams

CVE-2009-4501 is a remote denial-of-service flaw in Zabbix Server before 1.6.8. A malformed request missing expected field separators can crash the server. The business risk is loss of monitoring visibility rather than data theft, based on the provided sources. Exposure is most likely where legacy Zabbix Server versions before 1.6.8 remain reachable by untrusted hosts or broad internal networks. The provided affected-product metadata is incomplete, so version inventory is essential. Treat this as a legacy resilience issue. It can disrupt monitoring and incident response visibility, especially if an old Zabbix Server is exposed. Prioritize remediation when Zabbix is business-critical or internet-accessible. Mitigation focus: Upgrade Zabbix Server to 1.6.8 or a supported later release.; Restrict Zabbix Server access to trusted management networks only.; Review vendor guidance in the linked Zabbix issue and advisories..
