CVE-2018-18369: Norton Security (Windows client) prior to 22.16.3 and SEP SBE (Windows client) prior to Cloud Agent 3.00.31...

Norton Security (Windows client) prior to 22.16.3 and SEP SBE (Windows client) prior to Cloud Agent 3.00.31.2817, NIS-22.15.2.22 & SEP-12.1.7484.7002, may be susceptible to a DLL Preloading vulnerability, which is a type of issue that can occur when an application looks to call a DLL for execution and an attacker provides a malicious DLL to use instead.

Security readout for executives and security teams

Older Windows clients for Norton Security and Symantec Endpoint Protection Small Business Edition may load the wrong DLL if an attacker can place a malicious library where the application looks first. That can turn normal product execution into attacker-controlled code execution. The public bundle does not provide CVSS, observed exploitation, or detailed impact. Exposure is limited to Windows endpoints running the named legacy Symantec/Norton client versions. Organizations with retired consumer Norton installs, old SEP SBE cloud agents, or unmanaged Windows assets are most likely to miss this. Treat this as a targeted hygiene issue for legacy endpoint-security software, not an emergency based on the provided evidence. Prioritize verification where old Symantec/Norton agents remain deployed, because security tools often run broadly and may have elevated trust. Mitigation focus: Upgrade Norton Security Windows client to 22.16.3 or later.; Upgrade SEP SBE Windows client to Cloud Agent 3.00.31.2817 or later.; Review Symantec advisory SYMSA1479 for product-specific update guidance..
