Cross-site scripting (XSS) vulnerability in Mozilla Thunderbird 17.x through 17.0.8, Thunderbird ESR 17.x through 17.0.10, and SeaMonkey before 2.20 allows user-assisted remote attackers to inject arbitrary web script or HTML via an e-mail message containing a data: URL in a (1) OBJECT or (2) EMBED element, a related issue to CVE-2013-6674.

Security readout for executives and security teams

This is an old email-client XSS issue. A crafted email could cause Mozilla Thunderbird or SeaMonkey to run attacker-supplied script or HTML when a user interacts with malicious message content. Business risk is mainly for organizations still running legacy Mozilla mail clients. Exposure is most likely where old Thunderbird ESR 17.x, Thunderbird 17.x, or SeaMonkey versions remain installed or embedded in managed desktop images. Prioritize remediation if legacy Mozilla mail clients are still used. For modern environments without these versions, treat this as a legacy hygiene issue rather than an urgent enterprise-wide incident. Mitigation focus: Inventory Thunderbird and SeaMonkey versions across endpoints.; Upgrade affected clients to supported vendor-maintained releases.; Review Mozilla MFSA-2014-14 and CERT guidance for vendor-specific remediation..
