| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2021-10-19 | CVE-2021-31375 | Unspecified vulnerability in Juniper Junos An Improper Input Validation vulnerability in routing process daemon (RPD) of Juniper Networks Junos OS devices configured with BGP origin validation using Resource Public Key Infrastructure (RPKI), allows an attacker to send a specific BGP update which may cause RPKI policy-checks to be bypassed. | 5.3 |
| 2021-10-19 | CVE-2021-31386 | Unspecified vulnerability in Juniper Junos A Protection Mechanism Failure vulnerability in the J-Web HTTP service of Juniper Networks Junos OS allows a remote unauthenticated attacker to perform Person-in-the-Middle (PitM) attacks against the device. | 5.9 |
| 2021-07-15 | CVE-2021-0289 | Time-of-check Time-of-use (TOCTOU) Race Condition vulnerability in Juniper Junos When user-defined ARP Policer is configured and applied on one or more Aggregated Ethernet (AE) interface units, a Time-of-check Time-of-use (TOCTOU) Race Condition vulnerability between the Device Control Daemon (DCD) and firewall process (dfwd) daemons of Juniper Networks Junos OS allows an attacker to bypass the user-defined ARP Policer. | 5.3 |
| 2021-07-15 | CVE-2021-0291 | Information Exposure vulnerability in Juniper Junos 15.1/17.3/17.4 An Exposure of System Data vulnerability in Juniper Networks Junos OS and Junos OS Evolved, where a sensitive system-level resource is not being sufficiently protected, allows a network-based unauthenticated attacker to send specific traffic which partially reaches this resource. | 6.5 |
| 2021-04-22 | CVE-2021-0271 | Double Free vulnerability in Juniper Junos 12.3/15.1 A Double Free vulnerability in the software forwarding interface daemon (sfid) process of Juniper Networks Junos OS allows an adjacently-connected attacker to cause a Denial of Service (DoS) by sending a crafted ARP packet to the device. | 6.5 |
| 2021-04-22 | CVE-2021-0270 | Use After Free vulnerability in Juniper Junos 18.1 On PTX Series and QFX10k Series devices with the "inline-jflow" feature enabled, a use after free weakness in the Packet Forwarding Engine (PFE) microkernel architecture of Juniper Networks Junos OS may allow an attacker to cause a Denial of Service (DoS) condition whereby one or more Flexible PIC Concentrators (FPCs) may restart. | 5.9 |
| 2021-04-22 | CVE-2021-0267 | Improper Input Validation vulnerability in Juniper Junos An Improper Input Validation vulnerability in the active-lease query portion in JDHCPD's DHCP Relay Agent of Juniper Networks Junos OS allows an attacker to cause a Denial of Service (DoS) by sending a crafted DHCP packet to the device thereby crashing the jdhcpd DHCP service. | 6.5 |
| 2021-04-22 | CVE-2021-0257 | Memory Leak vulnerability in Juniper Junos On Juniper Networks MX Series and EX9200 Series platforms with Trio-based MPCs (Modular Port Concentrators) where Integrated Routing and Bridging (IRB) interfaces are configured and mapped to a VPLS instance or a Bridge-Domain, certain Layer 2 network events at Customer Edge (CE) devices may cause memory leaks in the MPC of Provider Edge (PE) devices which can cause an out of memory condition and MPC restart. | 6.5 |
| 2021-04-22 | CVE-2021-0247 | Race Condition vulnerability in Juniper Junos A Race Condition (Concurrent Execution using Shared Resource with Improper Synchronization) vulnerability in the firewall process (dfwd) of Juniper Networks Junos OS allows an attacker to bypass the firewall rule sets applied to the input loopback filter on any interfaces of a device. | 5.5 |
| 2021-04-22 | CVE-2021-0242 | Allocation of Resources Without Limits or Throttling vulnerability in Juniper Junos A vulnerability due to the improper handling of direct memory access (DMA) buffers on EX4300 switches on Juniper Networks Junos OS allows an attacker sending specific unicast frames to trigger a Denial of Service (DoS) condition by exhausting DMA buffers, causing the FPC to crash and the device to restart. | 6.5 |
