Date Discovered April 8, 2008
Description Microsoft VBScript and JScript are prone to a remote code-execution vulnerability because they fail to adequately handle user-supplied input.
Attackers can leverage this issue by enticing an unsuspecting user to view a malicious web document. Successful exploits would allow arbitrary code to run with the privileges of the victim.
These versions are affected:
VBScript 5.6 and earlier
JScript 5.6 and earlier
- HP Storage Management Appliance 2.1
- Microsoft JScript 5.1
- Microsoft JScript 5.6
- Microsoft VBScript 5.1
- Microsoft VBScript 5.6
- Nortel Networks CallPilot 1002rp
- Nortel Networks CallPilot 200i
- Nortel Networks CallPilot 201i
- Nortel Networks CallPilot 702t
- Nortel Networks CallPilot 703t
Run all software as a nonprivileged user with minimal access rights. To limit the potential damage that successful exploits may achieve, run all nonadministrative software as an unprivileged user.
Deploy network intrusion detection systems to monitor network traffic for malicious activity. Deploy NIDS to monitor network traffic for signs of anomalous or suspicious activity. This may indicate exploit attempts or activity that results from successful exploits.
Do not follow links provided by unknown or untrusted sources. Attackers can exploit this vulnerability by enticing a user to visit a malicious website. Do not follow links provided by sources of questionable integrity. Filtering HTML from emails may help remove a possible vector for transmitting malicious links to users.
Do not open email messages from unknown or untrusted individuals.
Attackers could exploit this vulnerability through HTML email messages. Do not accept any email from sources of questionable integrity.
The vendor has released a security advisory and fixes. Please see the references for more information.
