Description:
Brett Moore has reported a vulnerability in SecureCRT, which can be exploited by malicious people to compromise a user's system.
The vulnerability is caused due to a design error, as the product allows an arbitrary configuration folder to be specified to the "telnet:" URI handler via the "/F" command line option.
This can e.g. be exploited by including a link to a remote configuration folder on a SMB share and trick a user into visiting a malicious web site containing the link.
Successful exploitation allows execution of arbitrary commands via a malicious logon script with the privileges of the user running SecureCRT.
The vulnerability has been reported in versions 4.1 and 4.0. Prior versions may also be affected.
Do you have this product installed on your home computer? Scan using the free Personal Software Inspector. Check if a vulnerable version is installed on computers in your corporate network, scan using the Network Software Inspector.
Solution:
Update to version 4.1.9.
