Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SI-10 Information Input Validation good match

prevent

Directly mandates validation of the API endpoint parameter to block SQL injection via crafted input lacking proper sanitization.

SI-2 Flaw Remediation good match

prevent

Requires identification, reporting, and correction of the specific SQL injection flaw in Synnefo IMS version 2023 and earlier.

AC-6 Least Privilege partial match

prevent

Enforces least privilege on the database account used by the application, limiting damage from SQL injection granting DB administrator access.

NVD Description

A SQL injection vulnerability exists in Synnefo Internet Management Software (IMS) version 2023 and earlier. This vulnerability occurs due to improper input validation in a specific API endpoint parameter allowing an attacker to manipulate SQL queries via crafted input. Successful…

exploitation could lead to unauthorized access to database records with DB administrator privileges which can be leveraged to escalate privileges further and execute arbitrary OS commands.

Deeper analysisAI

CVE-2023-37777 is a SQL injection vulnerability affecting Synnefo Internet Management Software (IMS) version 2023 and earlier. The flaw arises from improper input validation in a specific API endpoint parameter, enabling attackers to inject and manipulate SQL queries through crafted input. Assigned a CVSS v3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H) and mapped to CWE-89, it was published on 2025-01-22.

Remote attackers require only network access with no authentication, privileges, or user interaction to exploit this vulnerability over the network with low complexity. Successful exploitation grants unauthorized access to database records using DB administrator privileges, allowing attackers to escalate privileges further and execute arbitrary operating system commands.
