CVE-2010-5145: The Filtering Service in Websense Web Security and Web Filter before 6.3.1 Hotfix 136 and 7.x before 7.1.1...

Security readout for executives and security teams

This flaw can let a remote attacker knock Websense web filtering offline by sending a specially formed URI. The business impact is loss of web filtering, not documented data theft or server takeover. It matters most where legacy Websense filtering is still in the internet access path. Exposure is likely limited to organizations still running the named legacy Websense Web Security or Web Filter versions on Windows. Systems already updated to 6.3.1 Hotfix 136, 7.1.1, or later are outside the described affected range. Prioritize remediation if legacy Websense filtering controls business web access or policy enforcement. The known impact is outage, so urgency depends on reliance on this service and whether affected versions remain deployed. Mitigation focus: Upgrade to 6.3.1 Hotfix 136, 7.1.1, or later where applicable.; Check current vendor guidance for unsupported legacy Websense deployments.; Limit unnecessary network exposure to the Filtering Service..
