Cisco Secure Email Gateway Filters Bypassed Due to Malware Scanner Issue
22-Nov-22
In order to send malware using specially written emails, a researcher who wishes to remain anonymous has revealed a number of techniques that can be used to get around some of the filters in Cisco’s Secure Email Gateway appliance. The researcher emphasised that the threads must be made public right away because the attack complexity is minimal and exploits have already been made available by a third party.
The researcher stated they had spoken with the vendor but that they had not received a suitable response within the allotted timeframe in a post on the Full Disclosure email group on November 14.
