Synopsis

The remote device is missing a vendor-supplied security patch.

Description

According to its self-reported version, Cisco Expressway Series is affected by multiple vulnerabilities.

- A vulnerability in Cisco Expressway Series and Cisco TelePresence Video Communication Server (VCS) could allow an unauthenticated, remote attacker to conduct cross-site request forgery (CSRF) attacks that perform arbitrary actions on an affected device. Note: Cisco Expressway Series refers to Cisco Expressway Control (Expressway-C) devices and Cisco Expressway Edge (Expressway-E) devices. For more information about these vulnerabilities, see the Details [#details] section of this advisory.
(CVE-2024-20252, CVE-2024-20254)

- A vulnerability in the SOAP API of Cisco Expressway Series and Cisco TelePresence Video Communication Server could allow an unauthenticated, remote attacker to conduct a cross-site request forgery (CSRF) attack on an affected system. This vulnerability is due to insufficient CSRF protections for the web-based management interface of an affected system. An attacker could exploit this vulnerability by persuading a user of the REST API to follow a crafted link. A successful exploit could allow the attacker to cause the affected system to reload. (CVE-2024-20255)
