"Juniper Networks Patches Over 30 Vulnerabilities in Junos OS"

Networking equipment manufacturer Juniper Networks recently announced patches for more than 30 vulnerabilities in Junos OS and Junos OS Evolved, including nine high-severity flaws.  The most severe of these issues is an incorrect default permissions bug that allows an unauthenticated attacker with local access to a vulnerable device to create a backdoor with root privileges.  Tracked as CVE-2023-44194 (CVSS score of 8.4), the company noted that the flaw exists because a specific system directory has improper permissions associated with it.  Juniper’s patches also address six high-severity vulnerabilities in Junos OS and Junos OS Evolved that could lead to denial of service (DoS).  The company noted that five of these can be exploited remotely without authentication.  Impacting both Junos OS and Junos OS Evolved, the remaining two high-severity issues can be exploited to impact the stability of devices and the confidentiality and integrity of device operations, respectively.  The company noted that all the remaining flaws resolved with this week’s Junos OS and Junos OS Evolved updates are medium-severity vulnerabilities that could lead to DoS conditions, bypass of intended access restrictions, impact on the integrity of systems or connected networks, impact on system availability, credentials leak, configuration changes leak, DMA memory leak, or the incorrect forwarding of MAC addresses.
