The bug exists because in Netgear’s web UI authentication logic, the browser first sends the login information using the “set.cgi” function, and then polls “get.cgi” to get the session ID.

“An attacker with the same IP as a logging-in admin to hijack the session bootstrapping information, giving the attacker full admin access to the device web UI and resulting in a full compromise of the device,” according to Coldwind’s Draconian Fear writeup, also issued on Monday. It’s only exploitable if the attack occurs while an admin is in the process of logging in. The second bug carries a 7.4 CVSS rating, making it also high-severity. And, to be pwned, a switch must have Netgear’s Smart Control Center (SCC Control) enabled (which it is by default).

“Sending just this one TLV is enough to change the admin password on the device without knowing the previous password,” he said.Ĭaveats: An attacker needs to already have a foothold on the same corporate network as the target device in order to exploit the vulnerable system.

the type 10 TLV can be omitted from the chain and in such case neither the password verification takes place, nor does it seem to be required by any of the ‘set’ TLV handlers,” explained Coldwind.Īs an example of how this can be exploited, he noted that a “set” command that changes the password on an account to the one specified in the value portion of the header can be sent – and accepted. “However, the sccd daemon on this device DOES NOT enforce this, i.e. “The protocol itself is UDP-based and each datagram consists of a 32-byte header, followed by a Type/Length/Value chain, with each TLV consisting of a four-byte header (two bytes Type, two bytes Length), followed by the Value bytes,” Coldwind explained in his posting, issued Monday.īy analyzing Netgear administration tools, Coldwind uncovered that any “set” commands (used to define and determine the values of the system environment) require a password-authentication TLV to be first in the datagram. The researcher said that the issue exists within the Netgear Switch Discovery Protocol (NSDP), which is implemented by the sqfs/bin/sccd daemon (hence the flaw’s name). The Demon’s Cries bug carries a CVSS severity-rating score of 8.8, making it high severity.Īccording to the researcher, who goes by “Gynvael Coldwind,” an exploit would allow an authentication bypass, resulting in the attacker accessing an admin’s password and achieving full compromise of the device.

If exploited, the gear could allow cyberattackers to gain administrative privileges and completely take over the device, gaining the ability to disrupt corporate communications as well as to pivot to move laterally throughout an enterprise network. Netgear tracks the bugs as PSV-2021-0140, PSV-2021-0144 and PSV-2021-0145, but CVEs are pending for all three. Details on the third, Seventh Inferno, will be published after Sept. The bugs were patched on Friday with zero technical details made available, but the researcher has now released more details on the first two.
