CVE-2010-1913 in Dynamic Agent
Summary
by MITRE
The default configuration of pluginlicense.ini for the SdcWebSecureBase interface in tgctlcm.dll in Consona Live Assistance, Dynamic Agent, and Subscriber Assistance, when downloaded from a server operated by Telefonica or possibly other companies, contains an incorrect DNS whitelist that includes the DNS hostnames of home computers of many persons, which allows remote attackers to bypass intended restrictions on ActiveX execution by hosting an ActiveX control on an applicable home web server.

The vulnerability described in CVE-2010-1913 represents a critical configuration flaw within the SdcWebSecureBase interface of Consona Live Assistance software, specifically affecting tgctlcm.dll components. This issue stems from the default pluginlicense.ini configuration file which contains an improperly maintained DNS whitelist. The flaw manifests when the software is deployed through servers operated by Telefonica or similar service providers, creating a dangerous misconfiguration that compromises the security boundaries designed to protect users from malicious ActiveX controls.
The technical implementation of this vulnerability involves an incorrect DNS whitelist that inadvertently includes hostnames belonging to home computing environments rather than restricting access to legitimate corporate or service provider domains. This misconfiguration creates a pathway where remote attackers can exploit the system by hosting malicious ActiveX controls on compromised home web servers that happen to match the whitelisted DNS entries. The vulnerability operates at the network level where DNS resolution bypasses the intended security restrictions, allowing unauthorized code execution through ActiveX controls that would normally be blocked by the security framework.
This flaw directly impacts the operational security posture of organizations using Consona Live Assistance software, particularly those operating in environments where remote access support is required. The vulnerability enables attackers to circumvent the intended security controls designed to prevent ActiveX execution from untrusted sources, potentially leading to full system compromise. The attack vector is particularly concerning because it leverages legitimate service provider infrastructure to bypass security restrictions, making detection and prevention more challenging for network administrators.
The security implications extend beyond simple access control violations as this vulnerability can facilitate broader exploitation attempts including credential theft, system reconnaissance, and potential lateral movement within networks. The flaw aligns with CWE-264, which addresses permissions, privileges, and access controls, and demonstrates how improper configuration management can create security vulnerabilities. From an attack framework perspective, this vulnerability would likely be categorized under ATT&CK technique T1190 for exploit known vulnerabilities and T1210 for exploitation of remote services, as it enables attackers to bypass security controls through legitimate software interfaces.
Organizations should implement immediate mitigations including manual review and correction of the pluginlicense.ini configuration files to remove the incorrect DNS entries, deployment of network monitoring to detect suspicious DNS resolution patterns, and implementation of additional network segmentation controls. The vulnerability highlights the importance of proper security configuration management and the need for regular security audits of deployed software components. System administrators should also consider implementing DNS filtering mechanisms and regular security assessments to prevent similar configuration errors that could create similar attack vectors in other software components.
