Authenticated root access via CLI path traversal
Published Jun 18, 2020 · Updated Nov 15, 2024
Path traversal in Cisco Enterprise NFV Infrastructure Software (NFVIS) allows local authenticated users to gain root shell access. The NFVIS CLI fails to validate command arguments, allowing traversal sequences to escape intended directories and read or overwrite arbitrary files. Exploitation requires valid administrative credentials and local CLI access on an affected Cisco device; the advisory reports no public exploitation.
