Detailsinfo

A vulnerability, which was classified as problematic, has been found in Cisco Expressway and TelePresence Video Communication Server up to X12.5.0 (Unified Communication Software). Affected by this issue is an unknown code block of the component Web-based Management Interface. The manipulation as part of a Request leads to a cross-site request forgery vulnerability. Using CWE to declare the problem leads to CWE-352. The web application does not, or can not, sufficiently verify whether a well-formed, valid, consistent request was intentionally provided by the user who submitted the request. Impacted is integrity. CVE summarizes:

A vulnerability in the FindMe feature of Cisco Expressway Series and Cisco TelePresence Video Communication Server (VCS) could allow an unauthenticated, remote attacker to conduct a cross-site request forgery (CSRF) attack and perform arbitrary actions on an affected system. The vulnerability is due to insufficient CSRF protections for the web-based management interface of the affected system. An attacker could exploit this vulnerability by persuading a user of the interface to follow a maliciously crafted link. A successful exploit could allow the attacker to perform arbitrary actions on an affected system with the privileges of the user. The arbitrary actions include adding an attacker-controlled device and redirecting calls intended for a specific user. For more information about CSRF attacks and potential mitigations, see Understanding Cross-Site Request Forgery Threat Vectors. This vulnerability is fixed in software version X12.5.1 and later.

The bug was discovered 04/17/2019. The weakness was released 04/18/2019 as cisco-sa-20190417-ex-vcs-xsrf as confirmed advisory (Website). The advisory is shared for download at tools.cisco.com. This vulnerability is handled as CVE-2019-1722 since 12/06/2018. The attack may be launched remotely. No form of authentication is required for exploitation. There are neither technical details nor an exploit publicly available.

The vulnerability was handled as a non-public zero-day exploit for at least 1 days. During that time the estimated underground price was around $5k-$25k.

Upgrading to version X12.5.1 eliminates this vulnerability.
