        AusCERT Advisory Summary
        ------------------------

Product:              IBM Tivoli Continuous Data Protection for Files 3.1.0
Operating System:     Windows
Impact:               Execute Arbitrary Code/Commands
Access:               Existing Account
CVE Names:            CVE-2007-5819
Member content until: Friday, December 07 2007


OVERVIEW:
 
        IBM Tivoli Continuous Data Protection (CDP) for Files uses 
        weak permissions on the CDP global download directory which 
        can enable a local attacker to distribute arbitrary files to 
        CDP clients [1].

 
IMPACT:

        If access permissions on the CDP global directory are not 
        restricted, pull installations can be abused to distribute 
        malicious files to CDP clients on the internal network.

 
MITIGATION:

        Restrict access to the CDP global directory to authorised users.
