CVE-2025-31352 in TeleControl Server Basic
Summary
by MITRE • 04/16/2025
A vulnerability has been identified in TeleControl Server Basic (All versions < V3.1.2.2). The affected application is vulnerable to SQL injection through the internally used 'UpdateGateways' method. This could allow an authenticated remote attacker to bypass authorization controls, to read from and write to the application's database and execute code with "NT AUTHORITY\NetworkService" permissions. A successful attack requires the attacker to be able to access port 8000 on a system where a vulnerable version of the affected application is executed on. (ZDI-CAN-25915)

The vulnerability CVE-2025-31352 represents a critical SQL injection flaw within TeleControl Server Basic versions prior to V3.1.2.2, specifically affecting the internal 'UpdateGateways' method. This vulnerability arises from inadequate input validation and sanitization within the application's database interaction layer, creating a pathway for malicious actors to manipulate SQL queries through crafted inputs. The flaw exists at the application logic level where user-supplied data is directly incorporated into database commands without proper parameterization or escaping mechanisms, making it susceptible to exploitation by attackers who can influence the query execution flow.
The security implications of this vulnerability extend beyond simple data theft, as it enables authenticated remote attackers to bypass authorization controls and gain unauthorized access to the application's database backend. The attack vector requires an attacker to have network access to port 8000 on the target system, which serves as the primary communication interface for the vulnerable TeleControl Server Basic application. Once exploited, the vulnerability allows for full read and write access to the database, enabling attackers to modify configuration data, exfiltrate sensitive information, and potentially establish persistent access. The execution of code with "NT AUTHORITY\NetworkService" permissions represents a significant privilege escalation opportunity, as this account typically has limited but critical system access that can be leveraged for further exploitation within the network environment.
The operational impact of CVE-2025-31352 is substantial for organizations relying on TeleControl Server Basic for network management and remote access control. Attackers exploiting this vulnerability can compromise the integrity and confidentiality of the entire system, potentially leading to complete system takeover or denial of service conditions. The vulnerability's presence in the 'UpdateGateways' method suggests that it may affect gateway configuration management, which could result in unauthorized network access or disruption of legitimate connectivity. This type of vulnerability aligns with CWE-89, which specifically addresses SQL injection flaws in software applications, and represents a common attack pattern documented in the MITRE ATT&CK framework under techniques related to credential access and privilege escalation. Organizations using vulnerable versions of this software face significant risk of lateral movement within their networks, as the compromised system could serve as a launching point for attacks against other networked systems.
Mitigation strategies for CVE-2025-31352 primarily focus on immediate software updates to version V3.1.2.2 or later, which contain the necessary patches to address the SQL injection vulnerability. Network segmentation should be implemented to restrict access to port 8000, limiting exposure to only authorized personnel and systems. Additionally, organizations should conduct thorough security assessments of their TeleControl Server Basic deployments, implementing network monitoring to detect anomalous access patterns or unauthorized database queries. The implementation of proper input validation, parameterized queries, and regular security testing can help prevent similar vulnerabilities from emerging in the future. Security teams should also establish incident response procedures specifically addressing SQL injection attacks and ensure that system administrators are trained to recognize and respond to potential exploitation attempts. Regular vulnerability scanning and penetration testing should be conducted to identify other potential entry points and ensure the overall security posture remains robust against evolving threats.
