Computers that don’t have network-level authentication could be remotely accessed and an attacker could install malicious code, according to reports. The bug contains an exact copy of information Microsoft only sent out to Microsoft Active Protection Program (MAPP) participants. MAPP gives a small, vetted group of security firms early access to vulnerability and patch information.

ThreatPost reports that researcher Luigi Auriemma says the exploit code found on a Chinese download site contains “the exact packet that he sent to TippingPoint's Zero Day Initiative in his original advisory on the vulnerability."

"ZDI engineers typically confirm the bug, work up a protection signature for TippingPoint's appliances and then send the data on to the affected company, in this case Microsoft,” says Auriemma.

Microsoft released a patch for the bug last Tuesday.
