Vulnerability from variot

Multiple vulnerabilities in Cisco SD-WAN products could allow an unauthenticated, remote attacker to execute denial of service (DoS) attacks against an affected device. For more information about these vulnerabilities, see the Details section of this advisory. plural Cisco SD-WAN The product contains a buffer error vulnerability.Denial of service (DoS) It may be put into a state. Cisco SD-WAN vEdge is a router from Cisco of the United States. This device can provide basic WAN, security and multi-cloud functions for Cisco SD-WAN solutions. Cisco SD-WAN vManage is a software from Cisco (Cisco) that provides software-defined network functions. This software is a way of network virtualization.

The symbolic link (symlink) creation function of Cisco SD-WAN software has a denial of service vulnerability. The vulnerability is caused by the program's failure to correctly verify and check the input to create a symbolic link. Attackers can create a symbolic link to the target file on a specific path. Use this vulnerability to overwrite arbitrary files owned by the root user on the affected system
