Technical ContextAI · show details

This vulnerability is classified as Path Traversal (CWE-22), which allows attackers to access files and directories outside the intended path. A vulnerability in the backup restore functionality of Cisco Nexus Dashboard could allow an authenticated, remote attacker to conduct a path traversal attack on an affected device. This vulnerability is due to insufficient validation of the contents of a backup file. An attacker with valid Administrator credentials could exploit this vulnerability by restoring a crafted backup file to an affected device. A successful exploit could allow the attacker to gain root privileges on the underlying shell on the affected device. Affected products include: Cisco Nexus Dashboard.
