eParakstītājs Windows auto-updater fetches and executes installer without certificate or integrity verification

Status: NEW  |  Advisory ID: CVE-2026-0392

Key Details

What to Know

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. (NVD)
