Security readout for executives and security teams
CVE-2013-7420 is a legacy document-handling flaw in Hancom Office 2010 SE. A specially crafted HML document can trigger a buffer overflow and potentially run attacker-controlled code when opened. Business risk is concentrated in environments that still use this older office suite or receive HML files from untrusted sources. Exposure is most likely on endpoints where Hancom Office 2010 SE is installed and users can open HML files. Risk increases where HML documents arrive by email, web download, shared folders, or business workflows. No other affected products are identified in the provided sources. Treat this as a legacy-software exposure issue. It is not currently supported by evidence of active exploitation in the provided sources, but arbitrary-code execution through documents can become serious where vulnerable software remains in use. Mitigation focus: Inventory and remove Hancom Office 2010 SE where it is no longer required.; Check Hancom or vendor guidance for fixed versions or supported replacements.; Restrict untrusted HML files at email, web, and file-sharing gateways..
