Vulnerability from github – Published: 2026-05-14 20:30 – Updated: 2026-06-09 10:20

Summary

electerm's encrypt method not safe enough

Details

Impact

Insecure sync encryption: deterministic AES-192-CBC with a fixed zero IV, constant KDF salt, and no MAC leads to confidentiality and integrity failures for synced bookmark/profile data. Attackers can crack common passwords across installs and perform undetected ciphertext bit-flips to alter config/bookmarks.

Vulnerability from cvelistv5 – Published: 2026-05-28 17:17 – Updated: 2026-05-29 15:29

Title

electerm's encrypt method not safe enough

Summary

electerm is an open-sourced terminal/ssh/sftp/telnet/serialport/RDP/VNC/Spice/ftp client. Prior to 3.9.5, deterministic AES-192-CBC with a fixed zero IV, constant KDF salt, and no MAC leads to confidentiality and integrity failures for synced bookmark/profile data. Attackers can crack common passwords across installs and perform undetected ciphertext bit-flips to alter config/bookmarks. This vulnerability is fixed in 3.9.5.
