CVE-2022-20664
Cisco Email Security Appliance and Cisco Secure Email and Web Manager Information Disclosure Vulnerability
In short
A flaw in Cisco's email security appliances allows authenticated administrators to extract sensitive information, including user credentials, from connected directory servers through improperly sanitized search queries. This exposes passwords and personal data stored in external authentication systems.
Technical detail
An authenticated remote attacker with operator-level credentials can exploit insufficient input sanitization in the web management interface's LDAP query functionality to perform directory injection attacks against external authentication servers. Successful exploitation enables retrieval of sensitive user credentials and other confidential data from the LDAP server without additional authorization.
Summary generated and translated by AI from the official description.
A vulnerability in the web management interface of Cisco Secure Email and Web Manager, formerly Cisco Security Management Appliance (SMA), and Cisco Email Security Appliance (ESA) could allow an authenticated, remote attacker to retrieve sensitive information from a Lightweight Directory Access Protocol (LDAP) external authentication server connected to an affected device. This vulnerability is due to a lack of proper input sanitization while querying the external authentication server. An attacker could exploit this vulnerability by sending a crafted query through an external authentication web page. A successful exploit could allow the attacker to gain access to sensitive information, including user credentials from the external authentication server. To exploit this vulnerability, an attacker would need valid operator-level (or higher) credentials.
