CVE-2010-1906 in Dynamic Agent
Summary
by MITRE
tgsrv.exe in the Repair Service in Consona Dynamic Agent, Repair Manager, Subscriber Activation, and Subscriber Agent relies on a predictable timestamp field to validate input to the \\.\pipe\__RepairService_pipe__company named pipe, which allows remote authenticated users to execute arbitrary code by obtaining the current time from (1) tcpip.sys or (2) an SMB2 service.

The vulnerability identified as CVE-2010-1906 resides within the tgsrv.exe component of Consona Dynamic Agent software suite, specifically within the Repair Service functionality. This flaw manifests in the validation mechanism of the \.\pipe\__RepairService_pipe__company named pipe communication channel, where the system relies on a predictable timestamp field for input validation purposes. The vulnerability affects multiple components including Repair Manager, Subscriber Activation, and Subscriber Agent modules, creating a widespread impact across the Consona Dynamic Agent ecosystem.
The technical exploitation of this vulnerability stems from the predictable nature of timestamp fields used in the validation process. Attackers can leverage this predictability by obtaining the current system time from either tcpip.sys or an SMB2 service, effectively allowing them to craft malicious payloads that bypass the timestamp validation checks. This approach represents a classic time-based attack vector where the attacker exploits the deterministic nature of timestamp generation to manipulate the validation logic. The vulnerability essentially creates a race condition or timing attack scenario where authenticated users can manipulate the temporal aspects of the validation process to gain unauthorized code execution privileges.
The operational impact of this vulnerability is significant as it transforms a legitimate authenticated user into a potential code execution vector. Remote authenticated attackers who can access the system through valid credentials can exploit this weakness to execute arbitrary code with the privileges of the affected service. This represents a privilege escalation scenario that could lead to complete system compromise, especially when considering that the Repair Service typically operates with elevated privileges. The vulnerability undermines the integrity of the named pipe communication mechanism and exposes the system to unauthorized code injection attacks.
From a cybersecurity perspective, this vulnerability aligns with CWE-330 Use of Insufficiently Random Values, which specifically addresses the use of predictable or insufficiently random data in security-sensitive contexts. The flaw also maps to ATT&CK technique T1059.007 Command and Scripting Interpreter: Python, as the arbitrary code execution capability could enable attackers to deploy Python-based payloads. Additionally, this vulnerability demonstrates characteristics of privilege escalation through service manipulation, relating to ATT&CK technique T1068 Local Port Forwarding and T1073 DLL Side-Loading, where the attacker leverages legitimate system components to execute malicious code. The attack requires only authenticated access, making it particularly dangerous as it can be exploited by insiders or compromised accounts with valid credentials.
Mitigation strategies should focus on implementing proper randomization of timestamp values used in validation processes, ensuring that timestamp fields are not predictable or easily obtainable through network services. System administrators should enforce strict access controls and monitor named pipe usage for anomalous patterns. The most effective remediation involves updating to patched versions of Consona Dynamic Agent software where the timestamp validation has been strengthened with cryptographically secure randomization. Network segmentation and privilege separation should also be implemented to limit the potential impact of successful exploitation, while regular security audits of named pipe implementations should be conducted to identify similar vulnerabilities in other system components.
