Kaspersky has fixed a security issue in Kaspersky Password Manager (KPM) for Windows that allowed a local user to recover the auto-filled credentials from a memory dump when the KPM extension for Google Chrome is used. To exploit the issue, an attacker must trick a user into visiting a login form of a website with the saved credentials, and the KPM extension must autofill these credentials. The attacker must then launch a malware module to steal those specific credentials.
The product stores sensitive information in cleartext in memory.
The sensitive memory might be saved to disk, stored in a core dump, or remain uncleared if the product crashes, or if the programmer does not properly clear the memory before freeing it. It could be argued that such problems are usually only exploitable by those with administrator privileges. However, swapping could cause the memory to be written to disk and leave it accessible to physical attack afterwards. Core dump files might have insecure permissions or be stored in archive files that are accessible to untrusted people. Or, uncleared sensitive memory might be inadvertently exposed to attackers due to another weakness.
