CVSS: 5.8EPSS: 0%CPEs: 83EXPL: 0CVE-2023-28961 – Junos OS: ACX Series: IPv6 firewall filter is not installed in PFE when "from next-header ah" is used
https://notcve.org/view.php?id=CVE-2023-28961
17 Apr 2023 — An Improper Handling of Unexpected Data Type vulnerability in IPv6 firewall filter processing of Juniper Networks Junos OS on the ACX Series devices will prevent a firewall filter with the term 'from next-header ah' from being properly installed in the packet forwarding engine (PFE). There is no immediate indication of an incomplete firewall filter commit shown at the CLI, which could allow an attacker to send valid packets to or through the device that were explicitly intended to be dropped. An indication ... • https://supportportal.juniper.net/JSA70586 • CWE-241: Improper Handling of Unexpected Data Type •
CVSS: 6.5EPSS: 0%CPEs: 81EXPL: 0CVE-2022-22155 – Junos OS: ACX5448: FPC memory leak due to IPv6 neighbor flaps
https://notcve.org/view.php?id=CVE-2022-22155
19 Jan 2022 — An Uncontrolled Resource Consumption vulnerability in the handling of IPv6 neighbor state change events in Juniper Networks Junos OS allows an adjacent attacker to cause a memory leak in the Flexible PIC Concentrator (FPC) of an ACX5448 router. The continuous flapping of an IPv6 neighbor with specific timing will cause the FPC to run out of resources, leading to a Denial of Service (DoS) condition. Once the condition occurs, further packet processing will be impacted, creating a sustained Denial of Service ... • https://kb.juniper.net/JSA11263 • CWE-400: Uncontrolled Resource Consumption CWE-401: Missing Release of Memory after Effective Lifetime CWE-772: Missing Release of Resource after Effective Lifetime •
CVSS: 6.5EPSS: 0%CPEs: 359EXPL: 0CVE-2021-0289 – Junos OS: User-defined ARP Policer isn't applied on Aggregated Ethernet (AE) interface until firewall process is restarted
https://notcve.org/view.php?id=CVE-2021-0289
15 Jul 2021 — 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. In this particular case the User ARP policer is replaced with default ARP policer. To review the desired ARP Policers and actual state one can run the command "show inte... • https://kb.juniper.net/JSA11191 • CWE-367: Time-of-check Time-of-use (TOCTOU) Race Condition •
CVSS: 6.5EPSS: 0%CPEs: 102EXPL: 0CVE-2021-0216 – Junos OS: ACX5448, ACX710: BFD sessions might flap due to high rate of transit ARP packets
https://notcve.org/view.php?id=CVE-2021-0216
22 Apr 2021 — A vulnerability in Juniper Networks Junos OS running on the ACX5448 and ACX710 platforms may cause BFD sessions to flap when a high rate of transit ARP packets are received. This, in turn, may impact routing protocols and network stability, leading to a Denial of Service (DoS) condition. When a high rate of transit ARP packets are exceptioned to the CPU and BFD flaps, the following log messages may be seen: bfdd[15864]: BFDD_STATE_UP_TO_DOWN: BFD Session 192.168.14.3 (IFL 232) state Up -> Down LD/RD(17/19) ... • https://kb.juniper.net/JSA11118 •
CVSS: 7.5EPSS: 0%CPEs: 344EXPL: 0CVE-2019-0043 – Junos OS: RPD process crashes upon receipt of a specific SNMP packet
https://notcve.org/view.php?id=CVE-2019-0043
10 Apr 2019 — In MPLS environments, receipt of a specific SNMP packet may cause the routing protocol daemon (RPD) process to crash and restart. By continuously sending a specially crafted SNMP packet, an attacker can repetitively crash the RPD process causing prolonged denial of service. No other Juniper Networks products or platforms are affected by this issue. Affected releases are Juniper Networks Junos OS : 12.1X46 versions prior to 12.1X46-D77 on SRX Series; 12.3 versions prior to 12.3R12-S10; 12.3X48 versions prior... • https://kb.juniper.net/JSA10935 • CWE-404: Improper Resource Shutdown or Release •
