Cisco IOS XE Software Command Injection Vulnerabilities

Advisory ansehen veröffentlicht 2018-09-26

Multiple vulnerabilities in the CLI parser of Cisco IOS XE Software could allow an authenticated, local attacker to execute commands on the underlying Linux shell of an affected device with root privileges. The vulnerabilities exist because the affected software improperly sanitizes command arguments, failing to prevent access to certain internal data structures on an affected device. An attacker who has privileged EXEC mode (privilege level 15) access to an affected device could exploit these vulnerabilities on the device by executing CLI commands that contain custom arguments. A successful exploit could allow the attacker to execute arbitrary commands with root privileges on the affected device. Cisco has released software updates that address these vulnerabilities. There are no workarounds that address these vulnerabilities.
