Juniper: >> Junos >> 12.1x45 Security Vulnerabilities
A Missing Synchronization vulnerability in the Packet Forwarding Engine (PFE) of Juniper Networks Junos OS on ACX5448 and ACX710 allows an unauthenticated, adjacent attacker to cause a Denial-of-Service (DoS).
If an interface flaps while the system gathers statistics on that interface, two processes simultaneously access a shared resource which leads to a PFE crash and restart.
This issue affects Junos OS:
* All versions before 20.4R3-S9,
* 21.2 versions before 21.2R3-S5,
* 21.3 versions before 21.3R3-S5,
* 21.4 versions before 21.4R3-S4,

An Incorrect Behavior Order in the routing engine (RE) of Juniper Networks Junos OS on EX4300 Series allows traffic intended to the device to reach the RE instead of being discarded when the discard term is set in loopback (lo0) interface. The intended function is that the lo0 firewall filter takes precedence over the revenue interface firewall filter.
This issue affects only IPv6 firewall filter.
This issue only affects the EX4300 switch. No other products or platforms are affected by this vulnerability.
This issue affects Juniper Networks Junos OS:
* All versions before 20.4R3-S10,
* from 21.2 before 21.2R3-S7,
* from 21.4 before 21.4R3-S6.

A Missing Release of Memory after Effective Lifetime vulnerability in the IKE daemon (iked) of Juniper Networks Junos OS on MX Series with SPC3, and SRX Series allows an administratively adjacent attacker which is able to successfully establish IPsec tunnels to cause a Denial of Service (DoS).
If specific values for the IPsec parameters local-ip, remote-ip, remote ike-id, and traffic selectors are sent from the peer, a memory leak occurs during every IPsec SA rekey which is carried out with a specific message sequence. This will eventually result in an iked process crash and restart.
The iked process memory consumption can be checked using the below command:
user@host> show system processes extensive | grep iked
PID USERNAME PRI NICE SIZE RES STATE C TIME WCPU COMMAND
56903 root 31 0 4016M 2543M CPU0 0 2:10 10.50% iked

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

A Missing Authentication for Critical Function vulnerability combined with a Generation of Error Message Containing Sensitive Information vulnerability in J-Web of Juniper Networks Junos OS on SRX Series and EX Series allows an unauthenticated, network-based attacker to access sensitive system information.
When a user logs in, a temporary file which contains the configuration of the device (as visible to that user) is created in the /cache folder. An unauthenticated attacker can then attempt to access such a file by sending a specific request to the device trying to guess the name of such a file. Successful exploitation will reveal configuration information.
This issue affects Juniper Networks Junos OS on SRX Series and EX Series:
* All versions earlier than 20.4R3-S9;
* 21.2 versions earlier than 21.2R3-S7;
* 21.3 versions earlier than 21.3R3-S5;
