Vulnerability from fkie_nvd - Published: 2019-05-03 17:29 - Updated: 2026-06-17 02:29
Severity
4.1 (Medium) - CVSS:3.0/AV:N/AC:L/PR:H/UI:N/S:C/C:N/I:L/A:N
4.3 (Medium) - CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N
Summary
A vulnerability in the management web interface of Cisco Expressway Series could allow an authenticated, remote attacker to perform a directory traversal attack against an affected device. The vulnerability is due to insufficient input validation on the web interface. An attacker could exploit this vulnerability by sending a crafted HTTP request to the web interface. A successful exploit could allow the attacker to bypass security restrictions and access the web interface of a Cisco Unified Communications Manager associated with the affected device. Valid credentials would still be required to access the Cisco Unified Communications Manager interface.
