Successful exploitation of this vulnerability could allow an attacker to interact with the database and retrieve critical data.
The following versions of SDG PnPSCADA products are affected:
3.2.1 IMPROPER NEUTRALIZATION OF SPECIAL ELEMENTS USED IN AN SQL COMMAND (‘SQL INJECTION’) CWE-89
The PnPSCADA system, a product of SDG Technologies CC, is afflicted by a critical unauthenticated error-based PostgreSQL Injection vulnerability. Present within the hitlogcsv.jsp endpoint, this security flaw permits unauthenticated attackers to engage with the underlying database seamlessly and passively. Consequently, malicious actors could gain access to vital information, such as Industrial Control System (ICS) and OT data, alongside other sensitive records like SMS and SMS Logs. The unauthorized database access exposes compromised systems to potential manipulation or breach of essential infrastructure data, highlighting the severity of this vulnerability.
CVE-2023-1934 has been assigned to this vulnerability. A CVSS v3 base score of 9.8 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H).
