Affected Products

Risk Level: Medium (Low/Medium/High/Critical)

  • F-Secure Key

Platforms

Risk Level: Medium (Low/Medium/High/Critical)

  • Windows

Notes

After gaining access to the victim's computer and performing a memory dump operation, it was found that decrypted user information is kept in the system memory in plaintext format. A successful exploitation of this would result in the attacker gaining access to victim's sensitive information such as stored passwords.

 

Mitigating Factor

An attacker will need to gain access to victim's computer prior to exploiting the vulnerability.
