Multiple vulnerabilities in TK8 Safe v.3.0.5

July 3, 2006

----

Summary:
TK8 Safe (www.tk8.com) is a password management application, which stores authentication details (and other sensitive 
data) in encrypted local folders. A number of issues have been discovered in version 3.0.5 of the application that 
present a risk to the integrity and availability of stored user data.

Business Impact:
Successful exploitation of the issues discovered could lead to system unavailability, the overwriting of sensitive 
data, and unrestricted access to sensitive data. Attacks against the application require limited technical knowledge.

Affected products:
TK8 Safe v.3.0.5 Standard and Pro Editions.

----

Description:
TK8 Safe v.3.0.5 allows users to set encrypted data repositories with weak or null passwords.

Remediation:
Assign a strong password to working folders. The vendor is addressing this issue in a forthcoming release (expected 
delivery date October 2006).

Description:
It is possible for a malicious attacker to brute force the password(s) for protected folder(s). No timeout 
functionality is instigated, meaning that although it is impossible for a legitimate user to 'lock out' their account, 
it is possible for a malicious attacker (or an automated agent) to have repeated attempts at directory access. 

Remediation:
Upgrade to TK8 Safe v.3.0.6 available from vendor website.

Description: 
It is possible for a malicious attacker to overwrite a legitimate directory. 

Remdiation: 
Upgrade to TK8 Safe v.3.0.6 available from vendor website.

Description: 
Insufficient bounds checking is in place within various fields within the application. By entering a string of 
sufficient length is is possible to create a variety a localised application DoS state.

Remdiation: 
Upgrade to TK8 Safe v.3.0.6 available from vendor website.
