CVE-2022-20676 (GCVE-0-2022-20676)

Vulnerability from cvelistv5 – Published: 2022-04-15 14:16 – Updated: 2024-09-16 18:54

Title

Cisco IOS XE Software Tool Command Language Privilege Escalation Vulnerability

Summary

A vulnerability in the Tool Command Language (Tcl) interpreter of Cisco IOS XE Software could allow an authenticated, local attacker to escalate from privilege level 15 to root-level privileges. This vulnerability is due to insufficient input validation of data that is passed into the Tcl interpreter. An attacker could exploit this vulnerability by loading malicious Tcl code on an affected device. A successful exploit could allow the attacker to execute arbitrary commands as root. By default, Tcl shell access requires privilege level 15.

Severity

5.1 (Medium)
