CVE-2023-44185
Last modified
CVE-2023-44185 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. An Improper Input Validation vulnerability in the routing protocol daemon (rpd) of Juniper Networks allows an attacker to cause a Denial of Service (DoS )to the device upon receiving and processing a specific malformed ISO VPN BGP UPDATE packet. Continued receipt of this packet will cause a sustained Denial of Service condition. This issue affects: * Juniper Networks Junos OS: * All versions prior to 20.4R3-S6; * 21.1 versions prior to 21.1R3-S5; * 21.2 versions prior to 21.2R3-S4; * 21.3 versions prior to 21.3R3-S3; * 21.4 versions prior to 21.4R3-S3; * 22.1 versions prior to 22.1R2-S2, 22.1R3; * 22.2 versions prior to 22.2R2-S1, 22.2R3; * 22.3 versions prior to 22.3R1-S2, 22.3R2. Juniper Networks Junos OS Evolved: * All versions prior to 20.4R3-S6-EVO; * 21.1-EVO version 21.1R1-EVO and later versions prior to 21.2R3-S4-EVO; * 21.3-EVO versions prior to 21.3R3-S3-EVO; * 21.4-EVO versions prior to 21.4R3-S3-EVO; * 22.1-EVO versions prior to 22.1R3-EVO; * 22.2-EVO versions prior to 22.2R2-S1-EVO, 22.2R3-EVO; * 22.3-EVO versions prior to 22.3R1-S2-EVO, 22.3R2-EVO. . EPSS estimates a 0.52% chance of exploitation in the next 30 days.
