Description

Juniper Junos OS is a network operating system used in Juniper Networks routers, switches, and security devices. It provides a modular, secure, and scalable platform for routing, switching, and network management.

Multiple vulnerabilities exist in Juniper Junos OS due to a buffer copy without checking size of input vulnerability in the Session Initialization Protocol (SIP) ALG, uncontrolled resource consumption, origin validation error, improper check for unusual or exceptional conditions in the Packet Forwarding Engine (PFE), access of uninitialized pointer in the routing protocol daemon (rpd), use of uninitialized resource in the Packet Forwarding Engine (PFE),a NULL pointer dereference flaw in the PFE management daemon (evo-pfemand),improper authentication validation, improper check for unusual or exceptional conditions vulnerability in the routing protocol daemon (rpd), multiple instances of OS command injection flaw in the CLI and a password aging flaw in the RADIUS client. A remote attacker could exploit these vulnerabilities by persuading a specially crafted request to gain elevated privileges on the targeted system.

Successful exploitation of these vulnerabilities could allow a remote attacker to execute arbitrary code, bypass security restrictions, gain elevated privileges, cause denial-of-service (DoS) or disclose sensitive information on the targeted system.
