CVSS: 7.5EPSS: 0%CPEs: 176EXPL: 0CVE-2023-0026 – 2023-06: Out-of-Cycle Security Bulletin: Junos OS and Junos OS Evolved: A BGP session will flap upon receipt of a specific, optional transitive attribute
https://notcve.org/view.php?id=CVE-2023-0026
An Improper Input Validation vulnerability in the Routing Protocol Daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated, network-based attacker to cause a Denial of Service (DoS). When a BGP update message is received over an established BGP session, and that message contains a specific, optional transitive attribute, this session will be torn down with an update message error. This issue cannot propagate beyond an affected system as the processing error occurs as soon as the update is received. This issue is exploitable remotely as the respective attribute can propagate through unaffected systems and intermediate AS (if any). Continuous receipt of a BGP update containing this attribute will create a sustained Denial of Service (DoS) condition. • https://supportportal.juniper.net/JSA71542 https://www.juniper.net/documentation/us/en/software/junos/bgp/topics/topic-map/bgp-error-messages.html • CWE-20: Improper Input Validation •
CVSS: 8.2EPSS: 0%CPEs: 30EXPL: 0CVE-2023-28960 – Junos OS Evolved: Docker repository is world-writeable, allowing low-privileged local user to inject files into Docker containers
https://notcve.org/view.php?id=CVE-2023-28960
An Incorrect Permission Assignment for Critical Resource vulnerability in Juniper Networks Junos OS Evolved allows a local, authenticated low-privileged attacker to copy potentially malicious files into an existing Docker container on the local system. A follow-on administrator could then inadvertently start the Docker container leading to the malicious files being executed as root. This issue only affects systems with Docker configured and enabled, which is not enabled by default. Systems without Docker started are not vulnerable to this issue. This issue affects Juniper Networks Junos OS Evolved: 20.4 versions prior to 20.4R3-S5-EVO; 21.2 versions prior to 21.2R3-EVO; 21.3 versions prior to 21.3R3-EVO; 21.4 versions prior to 21.4R2-EVO. • https://supportportal.juniper.net/JSA70585 • CWE-732: Incorrect Permission Assignment for Critical Resource •
CVSS: 7.5EPSS: 0%CPEs: 91EXPL: 0CVE-2023-28967 – Junos OS and Junos OS Evolved: An attacker sending genuine BGP packets causes an RPD crash
https://notcve.org/view.php?id=CVE-2023-28967
A Use of Uninitialized Resource vulnerability in the Border Gateway Protocol (BGP) software of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated network-based attacker to send specific genuine BGP packets to a device configured with BGP to cause a Denial of Service (DoS) by crashing the Routing Protocol Daemon (rpd). This issue is triggered when the packets attempt to initiate a BGP connection before a BGP session is successfully established. Continued receipt of these specific BGP packets will cause a sustained Denial of Service condition. This issue is triggerable in both iBGP and eBGP deployments. This issue affects: Juniper Networks Junos OS 21.1 version 21.1R1 and later versions prior to 21.1R3-S5; 21.2 version 21.2R1 and later versions prior to 21.2R3-S2; 21.3 version 21.3R1 and later versions prior to 21.3R3-S2; 21.4 versions prior to 21.4R3; 22.1 versions prior to 22.1R3; 22.2 versions prior to 22.2R2. • https://supportportal.juniper.net/JSA70591 • CWE-908: Use of Uninitialized Resource •
CVSS: 5.5EPSS: 0%CPEs: 53EXPL: 0CVE-2023-28980 – Junos OS and Junos OS Evolved: In a BGP rib sharding scenario an rpd crash will happen shortly after a specific CLI command is issued
https://notcve.org/view.php?id=CVE-2023-28980
A Use After Free vulnerability in the routing protocol daemon of Juniper Networks Junos OS and Junos OS Evolved allows a locally authenticated attacker with low privileges to cause Denial of Service (DoS). In a rib sharding scenario the rpd process will crash shortly after specific CLI command is issued. This issue is more likely to occur in a scenario with high route scale (>1M routes). This issue affects: Juniper Networks Junos OS * 20.2 version 20.2R3-S5 and later versions prior to 20.2R3-S6; * 20.3 version 20.3R3-S2 and later versions prior to 20.3R3-S5; * 20.4 version 20.4R3-S1 and later versions prior to 20.4R3-S4 * 21.1 version 21.1R3 and later versions prior to 21.1R3-S3; * 21.2 version 21.2R1-S2, 21.2R2-S1 and later versions prior to 21.2R3-S2; * 21.3 version 21.3R2 and later versions prior to 21.3R3; * 21.4 versions prior to 21.4R2-S1, 21.4R3; * 22.1 versions prior to 22.1R2.

https://notcve.org/view.php?id=CVE-2023-28981
An Improper Input Validation vulnerability in the kernel of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated, adjacent attacker to cause a Denial of Service (DoS). If the receipt of router advertisements is enabled on an interface and a specifically malformed RA packet is received, memory corruption will happen which leads to an rpd crash.
