CVE-2018-0278

Status: ModifiedMedium (6.5)—

A vulnerability in the management console of Cisco Firepower System Software could allow an unauthenticated, remote attacker to access sensitive data about the system. The vulnerability is due to improper cross-origin domain protections for the WebSocket protocol. An attacker could exploit this vulnerability by convincing a user to visit a malicious website designed to send requests to the affected application while the user is logged into the application with an active session cookie. A successful exploit could allow the attacker to retrieve policy or configuration information from the affected software and to perform another attack against the management console. Cisco Bug IDs: CSCvh68311.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
