Juniper: >> Junos Os Evolved Security Vulnerabilities
An Insertion of Sensitive Information into Log File vulnerability in Juniper Networks Junos OS and Junos OS Evolved allows a local, authenticated attacker with high privileges to access sensitive information.
When another user performs a specific operation, sensitive information is stored as plain text in a specific log file, so that a high-privileged attacker has access to this information.
This issue affects:
Junos OS:
* All versions before 21.2R3-S9;
*
21.4 versions before 21.4R3-S9;
* 22.2 versions before 22.2R2-S1, 22.2R3;
* 22.3 versions before 22.3R1-S1, 22.3R2;
Junos OS Evolved:
* All versions before before 22.1R3-EVO;
* 22.2-EVO versions before 22.2R2-S1-EVO, 22.2R3-EVO;
* 22.3-EVO versions before 22.3R1-S1-EVO, 22.3R2-EVO.

An Improper Check for Unusual or Exceptional Conditions vulnerability in the Packet Forwarding Engine (PFE) of Juniper Networks Junos OS Evolved on ACX 7000 Series allows an unauthenticated, adjacent attacker to cause a Denial-of-Service (DoS).
When a device has a Layer 3 or an IRB interface configured in a VPLS instance and specific traffic is received, the evo-pfemand processes crashes which causes a service outage for the respective FPC until the system is recovered manually.
This issue only affects Junos OS Evolved 22.4R2-S1 and 22.4R2-S2 releases and is fixed in 22.4R3. No other releases are affected.

An Improper Neutralization of Special Elements vulnerability in Juniper Networks Junos OS Evolved commands allows a local, authenticated attacker with low privileges to escalate their privileges to 'root' leading to a full compromise of the system.
The Junos OS Evolved CLI doesn't properly handle command options in some cases, allowing users which execute specific CLI commands with a crafted set of parameters to escalate their privileges to root on shell level.
This issue affects Junos OS Evolved:
* 21.1-EVO versions 21.1R1-EVO and later before 21.2R3-S8-EVO,
* 21.4-EVO versions before 21.4R3-S7-EVO,
* 22.1-EVO versions before 22.1R3-S6-EVO,
* 22.2-EVO versions before 22.2R3-EVO,
* 22.3-EVO versions before 22.3R2-EVO.

An Improper Check for Unusual or Exceptional Conditions vulnerability in the Packet Forwarding Engine (PFE) of Juniper Networks Junos OS Evolved on ACX7000 Series allows an unauthenticated, adjacent attacker to cause a
Denial-of-Service (DoS).
On all ACX 7000 Series platforms running
Junos OS Evolved, and configured with IRBs, if a Customer Edge device (CE) device is dual homed to two Provider Edge devices (PE) a traffic loop will occur when the CE sends multicast packets. This issue can be triggered by IPv4 and IPv6 traffic.
This issue affects Junos OS Evolved:
All versions from 22.2R1-EVO and later versions before 22.4R2-EVO,
This issue does not affect Junos OS Evolved versions before 22.1R1-EVO.

An Improper Handling of Exceptional Conditions vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows a logically adjacent downstream RSVP neighbor to cause kernel memory exhaustion, leading to a kernel crash, resulting in a Denial of Service (DoS).
The kernel memory leak and eventual crash will be seen when the downstream RSVP neighbor has a persistent error which will not be corrected.
System kernel memory can be monitored through the use of the 'show system kernel memory' command as shown below:
user@router> show system kernel memory
Real memory total/reserved: 4130268/ 133344 Kbytes
kmem map free: 18014398509110220 Kbytes
