2023-08-17 CVE-2023-36845 PHP External Variable Modification vulnerability in Juniper Junos
A PHP External Variable Modification vulnerability in J-Web of Juniper Networks Junos OS on EX Series and SRX Series allows an unauthenticated, network-based attacker to remotely execute code. Using a crafted request which sets the variable PHPRC an attacker is able to modify the PHP execution environment allowing the injection und execution of code. This issue affects Juniper Networks Junos OS on EX Series and SRX Series: * All versions prior to 20.4R3-S9; * 21.1 versions 21.1R1 and later; * 21.2 versions prior to 21.2R3-S7; * 21.3 versions prior to 21.3R3-S5; * 21.4 versions prior to 21.4R3-S5; * 22.1 versions prior to 22.1R3-S4; * 22.2 versions prior to 22.2R3-S2; * 22.3 versions prior to 22.3R2-S2, 22.3R3-S1; * 22.4 versions prior to 22.4R2-S1, 22.4R3; * 23.2 versions prior to 23.2R1-S1, 23.2R2.

2023-07-14 CVE-2023-36850 Improper Validation of Specified Index, Position, or Offset in Input vulnerability in Juniper Junos
An Improper Validation of Specified Index, Position, or Offset in Input vulnerability in the Connectivity Fault Management(CFM) module of Juniper Networks Junos OS on MX Series(except MPC10, MPC11 and LC9600) allows an adjacent attacker on the local broadcast domain to cause a Denial of Service(DoS). Upon receiving a malformed CFM packet, the MPC crashes.

2023-07-14 CVE-2023-36834 Incomplete Internal State Distinction vulnerability in Juniper Junos
An Incomplete Internal State Distinction vulnerability in the packet forwarding engine (PFE) of Juniper Networks Junos OS on SRX 4600 and SRX 5000 Series allows an adjacent attacker to cause a Denial of Service (DoS). If an SRX is configured in L2 transparent mode the receipt of a specific genuine packet can cause a single Packet Processing Engines (PPE) component of the PFE to run into a loop, which in turn will render the PPE unavailable.

2023-07-14 CVE-2023-36835 Improper Check for Unusual or Exceptional Conditions vulnerability in Juniper Junos
An Improper Check for Unusual or Exceptional Conditions vulnerability in the Packet Forwarding Engine (PFE) of Juniper Networks Junos OS on QFX10000 Series allows a network based attacker to cause a Denial of Service (DoS). If a specific valid IP packet is received and that packet needs to be routed over a VXLAN tunnel, this will result in a PFE wedge condition due to which traffic gets impacted.

2023-07-14 CVE-2023-36836 Use of Uninitialized Resource vulnerability in Juniper Junos
A Use of an Uninitialized Resource vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows a local, authenticated attacker with low privileges to cause a Denial of Service (DoS). On all Junos OS and Junos OS Evolved platforms, in a Multicast only Fast Reroute (MoFRR) scenario, the rpd process can crash when a a specific low privileged CLI command is executed.

2023-07-14 CVE-2023-36840 Reachable Assertion vulnerability in Juniper Junos
A Reachable Assertion vulnerability in Routing Protocol Daemon (RPD) of Juniper Networks Junos OS and Junos OS Evolved allows a locally-based, low-privileged attacker to cause a Denial of Service (DoS). On all Junos OS and Junos OS Evolved, when a specific L2VPN command is run, RPD will crash and restart.

2023-07-14 CVE-2023-36848 Improper Handling of Undefined Values vulnerability in Juniper Junos
An Improper Handling of Undefined Values vulnerability in the periodic packet management daemon (PPMD) of Juniper Networks Junos OS on MX Series(except MPC10, MPC11 and LC9600) allows an unauthenticated adjacent attacker to cause a Denial of Service (DoS). When a malformed CFM packet is received, it leads to an FPC crash.

2023-07-14 CVE-2023-36838 Out-of-bounds Read vulnerability in Juniper Junos
An Out-of-bounds Read vulnerability in the flow processing daemon (flowd) of Juniper Networks Junos OS on SRX Series allows a local, authenticated attacker with low privileges, to cause a Denial of Service (DoS). If a low privileged user executes a specific CLI command, flowd which is responsible for traffic forwarding in SRX crashes and generates a core dump.
