Vulnerability Title
Junos OS: If in a scaled CoS scenario information on CoS state is gathered mgd processes get stuck
Source: CVE Program / CVE List V5
Vulnerability Description
An Improper Handling of Exceptional Conditions vulnerability in the Class of Service daemon (cosd) of Juniper Networks Junos OS allows an authenticated, network-based attacker with low privileges to cause a limited Denial of Service (DoS).
In a scaled CoS scenario with 1000s of interfaces, when specific low privileged commands, received over NETCONF, SSH or telnet, are handled by cosd on behalf of mgd, the respective child management daemon (mgd) processes will get stuck. In case of (Netconf over) SSH this leads to stuck SSH sessions, so that when the connection-limit for SSH is reached, new sessions can't be established anymore. A similar behavior will be seen for telnet etc.
Stuck mgd processes can be monitored by executing the following command:
user@host> show system processes extensive | match mgd | match sbwait
