{"id":"CVE-2019-1854","aliases":["EUVD-2019-10411","GHSA-r7gg-wq5p-qhgv"],"status":"published","title":"Cisco Expressway Series Directory Traversal Vulnerability","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.","severity":{"version":"3.0","score":4.1,"vector":"CVSS:3.0/AV:N/AC:L/PR:H/UI:N/S:C/C:N/I:L/A:N","level":"medium","assessor":"cna","from":"cve"},"epss":{"day":"2026-11-08","score":0.03748,"percentile":0.89944,"model":"v2026.06.15"},"facts":{"in_kev":false,"known_exploited":false,"public_exploit":false,"fix_available":false},"cwes":["CWE-22"],"published":"2019-05-03T16:35:14Z","modified":"2026-06-17T02:29:27Z","products":[{"vendor":"cisco","product":"cisco expressway"},{"vendor":"cisco","product":"telepresence_video_communication_server"}],"references":[{"url":"https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190501-expressway-traversal","tags":["vendor-advisory","x_refsource_CISCO","x_transferred","Vendor Advisory"]},{"url":"http://www.securityfocus.com/bid/108154","tags":["vdb-entry","x_refsource_BID","x_transferred"]},{"url":"http://seclists.org/fulldisclosure/2019/May/28","tags":["mailing-list","x_refsource_FULLDISC","x_transferred"]},{"url":"https://seclists.org/bugtraq/2019/May/49","tags":["mailing-list","x_refsource_BUGTRAQ","x_transferred"]},{"url":"http://packetstormsecurity.com/files/152963/Cisco-Expressway-Gateway-11.5.1-Directory-Traversal.html","tags":["x_refsource_MISC","x_transferred"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2019-1854"},{"url":"https://github.com/advisories/GHSA-r7gg-wq5p-qhgv"}],"sources":{"cve":[{"id":"CVE-2019-1854","title":"Cisco Expressway Series Directory Traversal Vulnerability","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.
