Cisco ECE Vulnerability Could Lead to Username Enumeration Attacks

CVE-2022-20633

Summary

The vulnerability in the web-based management interface of Cisco ECE allows unauthenticated remote attackers to conduct username enumeration attacks. This issue arises from inconsistent authentication response behaviors when a connection is attempted. By exploiting this flaw, an attacker can send authentication requests to the affected device, successfully revealing valid usernames. Consequently, this information could be leveraged for further malicious activities targeting the compromised accounts. Cisco has issued software updates to mitigate this vulnerability, and no workarounds are available to address the issue.
