CVE-2010-0216 in MediaCAST
Summary
by MITRE
authenticate_ad_setup_finished.cfm in MediaCAST 8 and earlier allows remote attackers to discover usernames and cleartext passwords by reading the error messages returned for requests that use the UserID parameter.

The vulnerability identified as CVE-2010-0216 affects MediaCAST 8 and earlier versions, specifically targeting the authenticate_ad_setup_finished.cfm component. This flaw represents a critical security oversight that exposes sensitive authentication information through improperly handled error responses. The vulnerability stems from the application's failure to sanitize error messages returned to clients, creating a path for unauthorized information disclosure that directly impacts the system's authentication security model.
The technical implementation of this vulnerability occurs when the authenticate_ad_setup_finished.cfm script processes requests containing the UserID parameter. When malformed or unauthorized requests are submitted, the application generates error messages that inadvertently reveal username and password information in cleartext format. This occurs because the system does not properly validate or sanitize input parameters before processing authentication requests, allowing attackers to craft specific requests that trigger informative error responses. The flaw directly relates to CWE-209, which addresses the exposure of error information, and demonstrates how improper error handling can create information disclosure vulnerabilities.
The operational impact of this vulnerability extends beyond simple information disclosure, as it provides attackers with the means to enumerate valid user accounts and extract authentication credentials. Remote attackers can systematically probe the system using the UserID parameter to gather usernames and subsequently obtain cleartext passwords through the error response mechanism. This creates a significant risk for organizations using MediaCAST 8 or earlier versions, as the vulnerability enables account enumeration attacks and password harvesting without requiring elevated privileges or complex exploitation techniques. The vulnerability aligns with ATT&CK technique T1212, which covers exploitation for credential access through the exposure of system information.
Organizations affected by this vulnerability should implement immediate mitigations including disabling or removing the vulnerable component, implementing proper input validation and sanitization, and ensuring that error messages do not contain sensitive information. The recommended approach involves configuring the application to return generic error messages regardless of the input parameters, implementing proper authentication logging, and conducting thorough security reviews of all authentication components. Additionally, system administrators should consider implementing network-level protections such as intrusion detection systems to monitor for exploitation attempts and ensure that all authentication-related error handling follows security best practices as outlined in industry standards and frameworks.
