CVE-2026-3502
Description
TrueConf Client downloads application update code and applies it without performing verification. An attacker who is able to influence the update delivery path can substitute a tampered update payload. If the payload is executed or installed by the updater, this may result in arbitrary code execution in the context of the updating process or user.
Summary dbcve.org
TrueConf Client implements an insecure update mechanism that downloads and applies application updates without any cryptographic verification or integrity checks. An attacker with man-in-the-middle capabilities or control over the update delivery infrastructure can intercept and replace legitimate update packages with malicious payloads, leading to arbitrary code execution on the victim's system.
Mitigation
Implement cryptographic code signing and signature verification for all update packages. Use TLS with proper certificate validation for update downloads and verify update signatures/checksums before execution or installation.
