{"id":"CVE-2018-0382","aliases":["EUVD-2018-1205","GHSA-xf8h-gv6j-fvjf"],"status":"published","title":"Cisco Wireless LAN Controller Software Session Hijacking Vulnerability","description":"A vulnerability in the session identification management functionality of the web-based interface of Cisco Wireless LAN Controller (WLC) Software could allow an unauthenticated, remote attacker to hijack a valid user session on an affected system. The vulnerability exists because the affected software does not properly clear previously assigned session identifiers for a user session when a user authenticates to the web-based interface. An attacker could exploit this vulnerability by using an existing session identifier to connect to the software through the web-based interface. Successful exploitation could allow the attacker to hijack an authenticated user's browser session on the system. Versions 8.1 and 8.5 are affected.","severity":{"version":"3.0","score":5.3,"vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","level":"medium","assessor":"cna","from":"cve"},"epss":{"day":"2026-11-07","score":0.02041,"percentile":0.81264,"model":"v2026.06.15"},"facts":{"in_kev":false,"known_exploited":false,"public_exploit":false,"fix_available":false},"cwes":["CWE-287"],"published":"2019-04-17T21:35:14Z","modified":"2026-06-17T01:30:38Z","products":[{"vendor":"cisco","product":"cisco wireless lan controller (wlc)"},{"vendor":"cisco","product":"wireless_lan_controller_software"}],"references":[{"url":"https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190417-wlan-hijack","tags":["vendor-advisory","x_refsource_CISCO","x_transferred","Vendor Advisory"]},{"url":"http://www.securityfocus.com/bid/108005","tags":["vdb-entry","x_refsource_BID","x_transferred","Third Party Advisory","VDB Entry"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2018-0382"},{"url":"https://github.com/advisories/GHSA-xf8h-gv6j-fvjf"}],"sources":{"cve":[{"id":"CVE-2018-0382","title":"Cisco Wireless LAN Controller Software Session Hijacking Vulnerability","description":"A vulnerability in the session identification management functionality of the web-based interface of Cisco Wireless LAN Controller (WLC) Software could allow an unauthenticated, remote attacker to hijack a valid user session on an affected system.
