Argument injection vulnerability in Microsoft Internet Explorer, when running on systems with SeaMonkey installed and certain URIs registered, allows remote attackers to conduct cross-browser scripting attacks and execute arbitrary commands via shell metacharacters in a mailto URI, which are inserted into the command line that is created when invoking SeaMonkey.exe, a related issue to CVE-2007-3670.

Security readout for executives and security teams

This legacy issue affects Internet Explorer on systems that also have SeaMonkey installed and certain URI handlers registered. A malicious mailto link could cause command-line arguments to be interpreted by SeaMonkey, potentially leading to command execution. Exposure is narrow but serious where this old browser combination still exists. Likely limited to legacy Windows endpoints where Microsoft Internet Explorer and SeaMonkey coexist, with relevant URI registrations present. Modern environments are unlikely exposed unless they retain this old browser/protocol-handler configuration. Treat as a targeted legacy exposure issue. It is not broad modern internet risk, but command execution potential warrants fast cleanup if the affected browser configuration remains anywhere in production. Mitigation focus: Identify and retire legacy Internet Explorer plus SeaMonkey deployments.; Review vendor guidance for any historical patch or configuration advice.; Remove unnecessary URI protocol registrations that launch SeaMonkey..
