Description

UpSignOn for Windows before 7.19.0 contains a sensitive data exposure vulnerability that allows local attackers to recover the master password and decrypt vault contents by reading a retained backup key from the process memory of UpSignOn.exe, even after the vault has been re-locked. Attackers can extract the backup key from process memory to decrypt the encrypted master password backup stored in v6-vault1.DATA.txt, then use the recovered master password to decrypt the main vault and export all password manager entries in cleartext.
