- Severity: CVSS 7.1 (High), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:L
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=partial
- Known exploited (CISA KEV): no
- Published: 2024-10-16 · Updated: 2024-10-31

## 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 web-based management interface of Cisco ATA 190 Series Analog Telephone Adapter firmware could allow an unauthenticated, remote attacker to conduct a cross-site request forgery (CSRF) attack and perform arbitrary actions on an affected device. This vulnerability is due to insufficient CSRF protections for the web-based management interface of an affected device. An attacker could exploit this vulnerability by persuading a user to follow a crafted link. A successful exploit could allow the attacker to perform arbitrary actions on the affected device with the privileges of the targeted user.
