CVE-2010-1909 in Dynamic Agent
Summary
by MITRE
Buffer overflow in the RunCmd method in the SdcUser.TgConCtl ActiveX control in tgctlcm.dll in Consona Live Assistance, Dynamic Agent, and Subscriber Assistance allows remote attackers to execute arbitrary code via vectors involving "CreateProcess params."

The vulnerability identified as CVE-2010-1909 represents a critical buffer overflow flaw within the SdcUser.TgConCtl ActiveX control component of Consona Live Assistance software suite. This specific weakness exists in the RunCmd method of the tgctlcm.dll library, which is part of the Dynamic Agent and Subscriber Assistance products. The vulnerability stems from insufficient input validation and improper buffer handling when processing command parameters, creating a potential entry point for malicious actors to execute arbitrary code on affected systems. The flaw specifically manifests when the CreateProcess function receives improperly validated parameters, allowing attackers to craft malicious input that exceeds allocated buffer boundaries and overflows into adjacent memory regions.
The technical exploitation of this buffer overflow vulnerability follows established patterns documented in CWE-121, which categorizes buffer overflow conditions as critical security weaknesses. Attackers can leverage this vulnerability by crafting specially formatted input parameters that are passed to the CreateProcess function through the vulnerable RunCmd method. When the ActiveX control processes these malformed parameters, the excessive input causes memory corruption that can be manipulated to redirect program execution flow. This type of vulnerability falls under the ATT&CK technique T1059.007 for Command and Scripting Interpreter, as it enables remote code execution through the manipulation of command processing mechanisms within the ActiveX control.
The operational impact of CVE-2010-1909 extends beyond simple code execution, as it can enable full system compromise when exploited successfully. Organizations running affected versions of Consona Live Assistance software face significant risk of unauthorized access, data exfiltration, and persistent system compromise. The vulnerability's remote exploitability means that attackers do not require local system access to leverage the flaw, making it particularly dangerous in enterprise environments where ActiveX controls are often deployed for remote assistance and support functions. The attack surface is further expanded due to the widespread deployment of these ActiveX controls in customer support and help desk environments, where users may inadvertently browse to malicious websites or receive compromised emails containing the exploit.
Mitigation strategies for this vulnerability should focus on immediate remediation through vendor-provided patches and updates, as well as network-level defensive measures. Organizations should implement ActiveX control restrictions through group policies and browser security settings to prevent automatic execution of potentially malicious ActiveX components. The principle of least privilege should be enforced by limiting user permissions and restricting access to systems running vulnerable software. Network segmentation and monitoring solutions should be deployed to detect anomalous behavior patterns associated with buffer overflow exploitation attempts. Additionally, security teams should conduct comprehensive vulnerability assessments to identify all instances of the affected ActiveX controls and ensure that proper patch management procedures are in place to prevent similar vulnerabilities from remaining unaddressed in the future.
