Security readout for executives and security teams
This is an old filtering bypass in Aladdin eSafe Gateway 3.0 and earlier. A remote attacker could hide HTML SCRIPT tags using Unicode encoding so the gateway’s script filter missed them. The business concern is mostly legacy exposure: if this obsolete gateway is still relied on, malicious script content may pass controls users expect to block it. Exposure is likely limited to organizations still operating Aladdin eSafe Gateway 3.0 or earlier for HTML script filtering. Modern environments are unlikely to be affected unless this legacy product remains in mail, web, or gateway filtering paths. Prioritize discovery over emergency response. If no affected legacy gateway exists, no action is needed beyond documentation. If present, plan replacement or compensating controls because the product and vulnerability are very old and source evidence lacks a named patch. Mitigation focus: Identify whether Aladdin eSafe Gateway 3.0 or earlier exists in the environment.; Check vendor or legacy support guidance for available fixes or replacement paths.; Retire or isolate unsupported gateway filtering components where feasible..
