TCP/IP Sequence Prediction Blind Reset Spoofing DoS

medium Nessus Plugin ID 12213


New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


It was possible to send spoofed RST packets to the remote system.


The remote host is affected by a sequence number approximation vulnerability that allows an attacker to send spoofed RST packets to the remote host and close established connections. This may cause problems for some dedicated services (BGP, a VPN over TCP, etc).


Contact the vendor for a patch or mitigation advice.
