eParakstītājs 3.0 for Windows before version\n1.10.0 retrieves and executes its automatic updates over a channel that is not\nauthenticated or integrity-protected. On each launch the application fetches an\nupdate descriptor (XML) over TLS but accepts any TLS certificate (a permissive\nTrustManager and a HostnameVerifier that always returns true), does not verify\nany digital signature on the update descriptor, and does not verify the\nAuthenticode signature or a checksum of the downloaded installer before running\nit. A man-in-the-middle attacker able to redirect www.eparaksts.lv can serve a\ncrafted update descriptor pointing to an attacker-controlled executable, which\nthe client downloads and executes, resulting in arbitrary code execution on the\nvictim host.
