TITLE

Cisco Expressway Series Path traversal vulnerability

Trust: 1.4

sources: JVNDB: JVNDB-2019-003899 // CNNVD: CNNVD-201905-048

DESCRIPTION

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. Cisco Expressway Series Contains a path traversal vulnerability.Information may be obtained. An attacker can exploit this issue using directory-traversal characters ('../') to access and write arbitrary files or to execute arbitrary files. This issue is being tracked by Cisco Bug ID CSCvo47769. The vulnerability stems from a network system or product that fails to properly filter resources or special elements in file paths
