CVE-2022-20633
Cisco Enterprise Chat and Email Username Enumeration Vulnerability
In short
An attacker can discover valid usernames on Cisco ECE by observing how the system responds differently to login attempts with existing versus non-existing accounts. This information helps attackers prepare for further attacks like password guessing.
Technical detail
The web-based management interface exhibits information disclosure through inconsistent authentication error responses (CWE-204), allowing unauthenticated remote attackers to enumerate valid user accounts via differential analysis of HTTP responses. This username enumeration facilitates subsequent credential attacks and privilege escalation attempts.
Summary generated and translated by AI from the official description.
A vulnerability in the web-based management interface of Cisco ECE could allow an unauthenticated, remote attacker to perform a username enumeration attack against an affected device.
This vulnerability is due to differences in authentication responses that are sent back from the application as part of an authentication attempt. An attacker could exploit this vulnerability by sending authentication requests to an affected device. A successful exploit could allow the attacker to confirm existing user accounts, which could be used in further attacks.
Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
