- Severity: CVSS 6.0 (Medium), CNA
- Vector: CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:N
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=total
- Known exploited (CISA KEV): no
- Published: 2024-10-16 · Updated: 2024-10-16

## Affected

- Cisco Cisco Analog Telephone Adaptor (ATA) Software: 12.0.1 SR2, 11.1.0, 12.0.1 SR1, 11.1.0 MSR1, 12.0.1, 11.1.0 MSR2, 11.1.0 MSR3, 11.1.0 MSR4, 12.0.1 SR3, 11.2.1, 12.0.1 SR4, 11.2.2, 11.2.2 MSR1, 12.0.1 SR5, 11.2.3, 11.2.4

## Description

A vulnerability in the CLI of Cisco ATA 190 Series Analog Telephone Adapter firmware could allow an authenticated, local attacker with high privileges to execute arbitrary commands as the root user. This vulnerability exists because CLI input is not properly sanitized. An attacker could exploit this vulnerability by sending malicious characters to the CLI. A successful exploit could allow the attacker to read and write to the underlying operating system as the root user.
