Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SI-10 Information Input Validation good match

prevent

Directly validates vulnerable request parameters for filtering, searching, and sorting before incorporation into SQL queries, preventing SQL injection exploitation.

SI-2 Flaw Remediation good match

prevent

Remediates the specific SQL injection flaws by identifying, testing, and installing the vendor-provided upgrade to GestSup 3.2.60 or later.

RA-5 Vulnerability Monitoring and Scanning good match

preventdetect

Scans for vulnerabilities like this SQL injection in asset list functionality and remediates them based on risk assessments.

MITRE ATT&CK Enterprise TechniquesAI

T1190 Exploit Public-Facing Application Initial Access

Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.

Why these techniques?

SQL injection in a network-accessible web application directly enables exploitation of public-facing apps (T1190) and unauthorized data access from databases (T1213.006).

NVD Description

GestSup versions prior to 3.2.60 contain multiple SQL injection vulnerabilities in the asset list functionality. Multiple request parameters used to filter, search, or sort assets are incorporated into SQL queries without sufficient neutralization, allowing an authenticated attacker to manipulate database…

queries. Successful exploitation can result in unauthorized access to or modification of database contents depending on database privileges.

Deeper analysisAI

CVE-2026-22197 is a set of multiple SQL injection vulnerabilities (CWE-89) affecting GestSup versions prior to 3.2.60, specifically in the asset list functionality. Request parameters used for filtering, searching, or sorting assets are directly incorporated into SQL queries without adequate neutralization or sanitization. The vulnerability has a CVSS v3.1 base score of 8.1 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N), highlighting its high severity due to network accessibility and low complexity.

An authenticated attacker with low privileges (PR:L) can exploit these SQL injections remotely over the network without user interaction. By manipulating the vulnerable parameters, they can alter SQL queries to achieve unauthorized access to sensitive database contents or modify data, with impacts limited by the attacker's database privileges. Exploitation does not affect availability.

Mitigation guidance from the vendor's changelog at https://gestsup.fr/index.php?page=changelog and the VulnCheck advisory at https://www.vulncheck.com/advisories/gestsup-multiple-sqli-in-asset-list recommends upgrading to GestSup version 3.2.60 or later, where the SQL injection issues in the asset list have been addressed.
