CVE-2026-0392
eParakstītājs 3.0 for Windows – remote code execution via unauthenticated auto-update
- Published
- Updated
- Reserved
- Assigned by
- ENISA
Description
eParakstītājs 3.0 for Windows before version 1.10.0 retrieves and executes its automatic updates over a channel that is not authenticated or integrity-protected. On each launch the application fetches an update descriptor (XML) over TLS but accepts any TLS certificate (a permissive TrustManager and a HostnameVerifier that always returns true), does not verify any digital signature on the update descriptor, and does not verify the Authenticode signature or a checksum of the downloaded installer before running it. A man-in-the-middle attacker able to redirect www.eparaksts.lv can serve a crafted update descriptor pointing to an attacker-controlled executable, which the client downloads and executes, resulting in arbitrary code execution on the victim host.

What to do
Solution: Update eParakstītājs 3.0 to version 1.10.0 or later, in which the update channel is authenticated and the downloaded installer is signature-verified.
Workaround: Until updated, disable automatic updates and install new versions only from the official signed package obtained over a trusted network, verifying the Authenticode signature manually.
