CVE-2024-47491
Last modified
CVE-2024-47491 is a high-severity vulnerability rated 8.2/10 on the CVSS scale. An Improper Handling of Exceptional Conditions vulnerability in the Routing Protocol Daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows a network-based, unauthenticated attacker to cause Denial of Service (DoS). When a BGP UPDATE with malformed path attribute is received over an established BGP session, rpd crashes and restarts. Continuous receipt of a BGP UPDATE with a specifically malformed path attribute will create a sustained Denial of Service (DoS) condition for impacted devices. EPSS estimates a 0.57% chance of exploitation in the next 30 days.
Description
An Improper Handling of Exceptional Conditions vulnerability in the Routing Protocol Daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows a network-based, unauthenticated attacker to cause Denial of Service (DoS). When a BGP UPDATE with malformed path attribute is received over an established BGP session, rpd crashes and restarts. Continuous receipt of a BGP UPDATE with a specifically malformed path attribute will create a sustained Denial of Service (DoS) condition for impacted devices. While this issue affects systems running 32-bit and 64-bit systems, the probability of impact on 64-bit system is extremely low. According to KB25803 https://supportportal.juniper.net/s/article/Junos-How-to-check-if-Junos-OS-is-64-or-32-bit-on-a-router , customers can confirm 32-bit or 64-bit system via the ' show version detail ' command: lab@router> show version detail| match 32 JUNOS 32-bit kernel Software Suite lab@router> show version detail| match 64 JUNOS 64-bit kernel Software Suite This issue affects: Juniper Networks Junos OS: * All versions before 21.4R3-S8, * from 22.2 before 22.2R3-S4, * from 22.4 before 22.4R3-S3, * from 23.2 before 23.2R2-S1, * from 23.4 before 23.4R1-S2, 23.4R2.
