CVE-2020-26062

Cisco Integrated Management Controller Username Enumeration Vulnerability

Published Nov 18, 2024 CVSS 3.1 · 5.3 Medium EPSS < 1% KEV · Not listed

Description

A vulnerability in Cisco Integrated Management Controller could allow an unauthenticated, remote attacker to enumerate valid usernames within the vulnerable application.
The vulnerability is due to differences in authentication responses sent back from the application as part of an authentication attempt. An attacker could exploit this vulnerability by sending authentication requests to the affected application. A successful exploit could allow the attacker to confirm the names of administrative user accounts for use in further attacks.There are no workarounds that address this vulnerability.
