Summary

CVE-2023-29154 is a high-severity SQL Injection (CWE-89) vulnerability in Contec Conprosys Hmi System. Its CVSS base score is 7.2 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Protocol or Service Impersonation (T1001.003); ranked in the top 1% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.

Deeper analysis AI-assisted summary

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

CVE-2023-29154 is a SQL injection vulnerability in the CONPROSYS HMI System (CHS) versions prior to 3.5.3. The flaw resides in the query setting page, where insufficient input validation allows crafted data to be interpreted as SQL commands.

An attacker with administrative access to the affected product can supply malicious input to the query setting page and execute arbitrary SQL statements. Successful exploitation grants full control over the database, enabling impacts rated high for confidentiality, integrity, and availability under the CVSS vector AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H.

Vendor advisories published by CONTEC and coordinated through JVN recommend upgrading to CHS version 3.5.3 or later to address the issue; the referenced security bulletins detail the affected builds and the corrective release.

EPSS for the CVE rose from a low baseline to a peak of 0.1302 before receding to the current value of 0.0356, indicating a period of increased exploitation interest after disclosure.

Adversaries may attempt to access credential material stored in the process memory of the Local Security Authority Subsystem Service (LSASS).
T1003.002 Security Account Manager Credential Access
Adversaries may attempt to extract credential material from the Security Account Manager (SAM) database either through in-memory techniques or through the Windows Registry where the SAM database is stored.
T1003.003 NTDS Credential Access
Adversaries may attempt to access or create a copy of the Active Directory domain database in order to steal credential information, as well as obtain other information about domain members such as devices, users, and access rights.
T1005 Data from Local System Collection
Adversaries may search local system sources, such as file systems, configuration files, local databases, virtual machine files, or process memory, to find files of interest and sensitive data prior to Exfiltration.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.

addresses: CWE-89

Penetration testing uses SQL injection payloads against database interfaces, identifying and supporting fixes for SQL injection weaknesses.

addresses: CWE-89

Validates query inputs to prevent SQL syntax or command manipulation.

PR.PS-06 mostly match
blocks

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
blocks

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.
