Summary

CVE-2025-31350 is a high-severity SQL Injection (CWE-89) vulnerability in Siemens Telecontrol Server Basic. Its CVSS base score is 8.7 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 47% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

A vulnerability has been identified in TeleControl Server Basic versions prior to V3.1.2.2 consisting of an SQL injection flaw in the internally used UpdateBufferingSettings method. The issue is tracked as CVE-2025-31350 and carries a CVSS 4.0 score of 8.7 with CWE-89. Successful exploitation allows an authenticated remote attacker with network access to port 8000 to bypass authorization controls, read from and write to the application database, and execute code under the NT AUTHORITY\NetworkService account.

An attacker who can reach the affected service on port 8000 may leverage the injection to perform unauthorized database operations and achieve code execution with service-level privileges. The attack requires valid authentication credentials but does not need user interaction or special network positioning beyond reachability of the exposed port.

Siemens has published advisory SSA-443402 that addresses the issue and provides remediation guidance for TeleControl Server Basic.

The EPSS score for this CVE rose from a low of 0.0008 to a peak of 0.0100 after disclosure, indicating emerging exploitation interest that warrants renewed attention.

Vulnerability Data

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 'UpdateBufferingSettings' 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-25918)

Mitigating Controls (NIST 800-53 r5) AI

Developer testing and evaluation can discover SQLi flaws before deployment but does not stop their introduction.

Input validation directly stops untrusted data from reaching SQL query construction without neutralization.

Secure engineering principles require parameterized queries and input sanitization that structurally eliminate SQLi.

System monitoring can identify attempted SQLi exploitation via anomalous queries after the weakness exists.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly target injection flaws during coding and review so largely prevent CWE-89 introduction, yet the single broad outcome leaves residual risk from incomplete neutralization techniques or missed edge cases.

PR.AT-02 partial match
prevents

Training raises developer awareness of SQLi risks and can reduce introduction likelihood (partial) but removes none of the actual coding flaw's risk by itself since technical neutralization is still required.

finds

The same secure-coding and static-analysis activities surface missing neutralization of SQL metacharacters before the system is accepted.

prevents

Early warnings and shared best-practice information help organizations apply the latest remediation techniques against SQL-injection vulnerabilities.

prevents

Threat-intelligence feeds that surface new SQL-injection campaigns enable rapid updates to query-construction defenses and detection signatures before exploitation occurs.

prevents

Secure-coding rules and security testing phases mandate the use of parameterized queries or equivalent escaping, preventing the construction of dynamic SQL statements from untrusted input.

prevents

Language-specific secure coding rules, peer review and SAST together prevent the construction of SQL statements from untrusted data without proper parameterization or escaping.
