- 漏洞讨论

Symantec Norton AntiVirus contains a feature called LiveUpdate. LiveUpdate is a process that checks for new virus definitions over the internet, downloads and installs them from a Symantec site. This process can either be scheduled or performed manually.

Authentication credentials for the LiveUpdate service are stored in plaintext in the Windows registry. It is possible for a local attacker or malicious users on client machines to gain access to this information.

This issue has been reported for LiveUpdate running with Symantec Norton AntiVirus Corporate Edition. It is possible that other products which use the LiveUpdate service may also be affected by this vulnerability.

Symantec has reported that LiveUpdate 1.5 and 1.6 encrypt the username and
password by default. It is believed that this is not a LiveUpdate issue, it is an internal server issue when passing the username and password to the client system.

- 漏洞利用

The attacker may use regedit to search for the authentication credentials.

- 解决方案

Symantec has acknowledged this issue and an update will be made available. The release date of this fix is not yet known.
