SQL Injection vulnerability in Qcms v.6.0.6 allows a remote attacker to execute arbitrary code

AnalysisAI

SQL injection in Qcms 6.0.6 lets remote attackers inject arbitrary SQL through the backend tableField action, enabling database compromise and, per the advisory tagging, escalation toward arbitrary code execution. The flaw is documented in a white-box audit write-up but is not listed in CISA KEV, and its EPSS probability is low (0.20%, 10th percentile), indicating no evidence of widespread automated exploitation yet. …

Vulnerability AssessmentAI

Exploitation The vulnerable code path is the Qcms backend 'tableField' action, as named in the referenced audit report - exploitation requires the attacker to reach and submit input to that backend/admin function on a Qcms 6.0.6 instance. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment Signals conflict and must be weighed rather than taken at face value. … 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 or fixed version is identified in the available data, so no upgrade target can be cited; monitor the Qcms project for an official 6.0.6-superseding release. … Detailed patch versions, workarounds, and compensating controls in full report.

Recommended ActionAI

Within 24 hours, inventory all systems to identify any production deployments of Qcms 6.0.6 and immediately isolate affected instances from external network access. …
