This vulnerability has been flagged as being a Myth/Fake.


Disclosure Date


Multiple security products have been reported to be vulnerable to an "argument switch" race condition issue, that may allow an attacker to bypass scanning activity or elevate privileges. The vulnerability is also known as a TOCTTOU (time-of-check-to-time-of-use) attack, relying on a weakness in the operating system for SSDT hooking activity. Several vendors have replied to this research pointing out that the 'attack' is extremely limited, and while interesting, poses no threat to the software. The vendors point out that the attack can only be implemented if the scanning software misses a piece of malware, allowing the malware to then bypass scanning, which it already did. Once the attack can be launched, it might be useful for hiding the presence of the malware, but malware writers have used much more reliable methods for many years. Finally, this attack works on Windows XP, and does not work on subsequent versions of Windows. In summary, this attack can only be launched to bypass the security software, if the software has already been bypassed.
