CVE-2010-1907 in Dynamic Agent
Summary
by MITRE
The SdcUser.TgConCtl ActiveX control in tgctlcm.dll in Consona Live Assistance, Dynamic Agent, and Subscriber Assistance allows remote attackers to discover the username of the client user, and consequently determine a pathname to a certain user directory, via a call to the GetUserName method.

The vulnerability identified as CVE-2010-1907 resides within the SdcUser.TgConCtl ActiveX control component of Consona Live Assistance software, specifically in the tgctlcm.dll library. This represents a classic information disclosure flaw that occurs when an ActiveX control fails to properly sanitize or restrict access to sensitive system information. The vulnerability is particularly concerning because it enables remote attackers to extract username information from client systems, which can then be leveraged to determine user directory paths and potentially facilitate further attacks.
The technical mechanism behind this vulnerability involves the GetUserName method within the ActiveX control, which is designed to return the username of the currently logged-in user. However, the implementation lacks proper access controls or input validation, allowing unauthorized remote execution of this method from external attackers. When exploited, this method reveals the client-side username, which serves as a critical piece of information for attackers seeking to map user directories and potentially access sensitive files or perform directory traversal attacks. The vulnerability is classified under CWE-200 as "Information Exposure" and can be mapped to ATT&CK technique T1083 "File and Directory Discovery" as it enables attackers to gather information about user locations and system structure.
The operational impact of this vulnerability extends beyond simple information disclosure, as it creates a foundation for more sophisticated attacks within the target environment. Once an attacker has determined the username, they can construct specific attack vectors targeting user directories, potentially leading to privilege escalation, lateral movement, or data exfiltration. The vulnerability affects multiple Consona products including Live Assistance, Dynamic Agent, and Subscriber Assistance, indicating a widespread exposure across the product line. This exposure is particularly dangerous in enterprise environments where these tools might be deployed to support customer service operations, creating potential attack vectors through legitimate business processes.
Mitigation strategies for this vulnerability should focus on immediate remediation through software updates provided by the vendor, as well as network-level protections such as disabling ActiveX controls in web browsers and implementing proper access controls. Organizations should also consider network segmentation to limit the exposure of systems running these components and implement monitoring for suspicious ActiveX control usage. The vulnerability highlights the importance of proper input validation and access control mechanisms in ActiveX components, and serves as a reminder of the security risks associated with legacy software components that may not receive adequate security updates or patches. Security teams should conduct comprehensive inventory assessments to identify all instances of this ActiveX control and ensure proper patch management procedures are in place to address similar vulnerabilities in other software components.
