Cisco Bug: CSCun36631 - EHN: URL Defang operation should account for DNS Spoofing
Nov 27, 2020
- Cisco IronPort Email Security Appliance Software
Known Affected Releases
Symptom: Links from some sites are able to be followed even though they were supposed to have been defanged. Conditions: - The domain owner has taken steps to ensure that typos in the URL before the domain name are accounted for (a valid DNS response to a URL similar to blockedwww.eharmony.com). - The URL ends with a slash character (/) such that the "BLOCKED" that is added to the end is added after the trailing slash (/).
