DescriptionCVE.org

ScadaLTS 2.8.1-release-candidate build 0 is affected by an Authenticated Blind SQL Injection

The /api/events/search endpoint accepts a JSON body containing a sortBy array. The values in this array are concatenated directly into the SQL ORDER BY clause without any sanitization or parameterization. This allows authenticated users with the ROLE_USER role to perform time-based and boolean-based blind SQL injection to extract arbitrary data from the database, including password hashes of all users.

The endpoint is accessible to any authenticated user with ROLE_USER, ROLE_ADMIN, or ROLE_PUBLIC via POST /api/events/search as defined in spring-security.xml.

AnalysisAI

Authenticated blind SQL injection in ScadaLTS 2.8.1-release-candidate build 0 lets any logged-in user with the lowest privilege tier (ROLE_USER, ROLE_ADMIN, or ROLE_PUBLIC) extract arbitrary database contents, including password hashes for every account on the platform. The flaw lives in the JSON sortBy array accepted by POST /api/events/search, whose values are concatenated straight into the SQL ORDER BY clause with no sanitization or parameterization, forcing attackers to use slower time-based and boolean-based inference rather than in-band extraction. …

Vulnerability AssessmentAI

Exploitation Requires an authenticated ScadaLTS session with any of ROLE_USER, ROLE_ADMIN, or ROLE_PUBLIC (per spring-security.xml), so the attacker needs valid credentials but only the lowest privilege tier - deployments that provision public or self-service low-privilege accounts effectively lower this barrier. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment This is a genuine but moderate-priority issue whose CVSS 6.5 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N) is well-calibrated and I agree with it. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario Full exploit scenario with step-by-step reproduction available after sign-in.
Remediation No vendor-released patch was identified at time of analysis, so remediation depends on compensating controls until an upstream fix ships. … Detailed patch versions, workarounds, and compensating controls in full report.

Threat intelligence, references, and detailed analysis are available after sign-in.
