CyberRota Analysis

AI-Generated

eParakstītājs 3.0 for Windows prior to version 1.10.0 is vulnerable due to its insecure update mechanism, which allows an attacker to intercept and serve malicious updates without any authentication or integrity checks. This flaw can lead to arbitrary code execution on the victim's system if a man-in-the-middle attack is successfully executed. Organizations using this application should prioritize patching to mitigate the risk of exploitation.

Original NVD 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.
