CVE-2018-0382: Cisco Wireless Lan Controller Software

High severity, CVSS 7.5. EPSS: 2% chance of exploitation in the next 30 days.

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.

Affected products

• Cisco Wireless Lan Controller Software: version 8.1(111.0) only; version 8.5(120.0) only
