CVE-2021-34688

Personal Key disclosure via reversible log encryption

Published Jul 15, 2021 · Updated Aug 4, 2024

Information disclosure in IDrive RemotePC before 7.6.48 on Windows allows local users to recover the system Personal Key from logs. The application writes an encrypted copy of the key to world-readable %PROGRAMDATA% log files and protects it with a reversible hard-coded static key. Any locally authenticated account can read and decrypt the logged value, exposing the credential used to access the system remotely.
