Advisory Number : SRT2004-12-14-0322
Product : Symantec LiveUpdate
Version : Prior to version 2.5
Vendor : http://symantec.com/techsupp/files/lu/lu.html
Class : Local
Criticality : High (to users of the below listed products)
Products Affected : Symantec Windows LiveUpdate prior to v2.5 : Symantec Norton SystemWorks 2001-2005 : Symantec Norton AntiVirus 2001-2005 : Symantec Norton AntiVirus Pro 2001-2004 : Symantec Norton Internet Security 2001-2005 : Norton Internet Security Pro 2001-2004 : Symantec Norton AntiSpam 2005 : Symantec AntiVirus for Handhelds Retail and Corporate Edition v3.0 Not Affected : Symantec Windows LiveUpdate v2.5 and later : Symantec Java LiveUpdate (all versions) : Symantec Enterprise products (Symantec Enterprise products do not support the Automatic LiveUpdate functionality with the exception of Symantec AntiVirus for Handhelds Corporate Edition v3.0)
The full technical details of this vulnerability can be found at: http://www.secnetops.com under the research section.
High Level Description : LiveUpdate allows local users to become SYSTEM What to do : run LiveUpdate and apply latest patches.
Proof Of Concept Status:
Functional, Contact SNO for details.
Symantec Automatic LiveUpdate, a functionality included with many Symantec retail products as well as on Symantec AntiVirus for Handhelds Corp v3.0, is launched by the system scheduler on system startup and then periodically after startup. Symantec LiveUpdate can automatically check for available updates to any supported Symantec products installed on the system using a scheduled task call NetDetect.
Vulnerable versions of the Symantec Automatic LiveUpdate are initially launched at startup and were being assigned Local System privileges. During the period when an interactive LiveUpdate session is available, and only during this session, a non-privileged user could potentially manipulate portions of the LiveUpdate GUI Internet options configuration functionality to gain elevated privilege on the local host. For example, the non-privileged user could gain privileges to search and edit all system files, assume full permission for directories and files on the host, or create new user accounts on the local system.
If exploited effectively this issue would permit a non-privileged user to gain privileged access on the local host. Symantec has produced a list of mitigating circumstances that reduce the risk of exploitation in the Automatic LiveUpdate feature.
Symantec Automatic LiveUpdate is only implemented in retail versions of Symantec products with the exception of Symantec AntiVirus for Handhelds Corporate Edition v3.0. This version uses Symantec Automatic LiveUpdate to check for essential updates when connected to the network.
The system is vulnerable only when the interactive LiveUpdate capability is activated and configured with the option to notify the user when updates are available. Single user systems are not a the same risk factor as multi-user systems in shared environments. Shared computers in university or office type environments with restricted or non-privileged user access are at high risk.
Symantec was notified of the vulnerability and fixes are available via LiveUpdate. Secure Network Operations thanks Symantec for being friendly and approachable during this advisory research and release process.
