CVE-2025-32841 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 'UnlockGateway' 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.

The vulnerability identified as CVE-2025-32841 affects TeleControl Server Basic versions prior to V3.1.2.2, representing a critical security flaw that undermines the integrity and confidentiality of the affected system. This vulnerability stems from improper input validation within the application's internal 'UnlockGateway' method, which processes user-supplied data without adequate sanitization or parameterization. The flaw exists in the application's database interaction layer where user-provided parameters are directly concatenated into SQL queries, creating an avenue for malicious input manipulation that bypasses normal authorization mechanisms.
The technical implementation of this vulnerability allows an authenticated remote attacker to exploit the SQL injection flaw through the designated port 8000, which serves as the primary communication channel for the TeleControl Server Basic application. The attacker can leverage this weakness to execute arbitrary SQL commands against the underlying database, potentially gaining read and write access to sensitive application data. The execution context of the malicious operations occurs with elevated privileges equivalent to "NT AUTHORITY\NetworkService", which provides significant system access capabilities including potential lateral movement and privilege escalation within the network environment. This privilege level represents a critical compromise as it grants the attacker substantial control over the application's operational functions and data repositories.
The operational impact of this vulnerability extends beyond simple data theft or modification, as it enables complete system compromise through code execution capabilities. An attacker could potentially establish persistent access to the system, modify application behavior, exfiltrate confidential information, or use the compromised system as a launch point for further attacks against adjacent network resources. The requirement for authentication to exploit this vulnerability does not mitigate the risk significantly, as the attacker could potentially obtain valid credentials through social engineering, credential theft, or other attack vectors. The attack surface is further constrained by the need for network access to port 8000, but this limitation does not prevent exploitation in environments where the service is exposed to untrusted networks.
Organizations affected by this vulnerability should immediately implement mitigations including updating to TeleControl Server Basic version V3.1.2.2 or later, which contains the necessary patches to address the SQL injection flaw. Network segmentation and access controls should be enforced to limit exposure of port 8000 to only trusted sources, while implementing additional monitoring for suspicious database access patterns and SQL injection attempts. Security teams should also conduct thorough vulnerability assessments of all systems running affected versions and consider implementing database activity monitoring solutions to detect anomalous behavior that might indicate exploitation attempts. The vulnerability aligns with CWE-89, which specifically addresses SQL injection flaws, and represents a significant risk under the ATT&CK framework's privilege escalation and defense evasion tactics, as it allows attackers to gain elevated system privileges and potentially evade detection mechanisms through the use of system-level accounts.
