CVE-2020-36195 — qnap / qts

Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')

An SQL injection vulnerability has been reported to affect QNAP NAS running Multimedia Console or the Media Streaming add-on. If exploited, the vulnerability allows remote attackers to obtain application information. QNAP has already fixed this vulnerability in the following versions of Multimedia Console and the Media Streaming add-on. QTS 4.3.3: Media Streaming add-on 430.1.8.10 and later QTS 4.3.6: Media Streaming add-on 430.1.8.8 and later QTS 4.4.x and later: Multimedia Console 1.3.4 and later We have also fixed this vulnerability in the following versions of QTS 4.3.3 and QTS 4.3.6, respectively: QTS 4.3.3.1624 Build 20210416 or later QTS 4.3.6.1620 Build 20210322 or later

Frequently Asked Questions

A security vulnerability is a weakness in software, hardware, or configuration that can be exploited to compromise confidentiality, integrity, or availability. Many vulnerabilities are tracked as CVEs (Common Vulnerabilities and Exposures), which provide a standardized identifier so teams can coordinate patching, mitigation, and risk assessment across tools and vendors.

CVSS (Common Vulnerability Scoring System) estimates technical severity, but it doesn't automatically equal business risk. Prioritize using context like internet exposure, affected asset criticality, known exploitation (proof-of-concept or in-the-wild), and whether compensating controls exist. A "Medium" CVSS on an exposed, production system can be more urgent than a "Critical" on an isolated, non-production host.

A vulnerability is the underlying weakness. An exploit is the method or code used to take advantage of it. A zero-day is a vulnerability that is unknown to the vendor or has no publicly available fix when attackers begin using it. In practice, risk increases sharply when exploitation becomes reliable or widespread.

Recurring findings usually come from incomplete Asset Discovery, inconsistent patch management, inherited images, and configuration drift. In modern environments, you also need to watch the software supply chain: dependencies, containers, build pipelines, and third-party services can reintroduce the same weakness even after you patch a single host. Unknown or unmanaged assets (often called Shadow IT) are a common reason the same issues resurface.

Use a simple, repeatable triage model: focus first on externally exposed assets, high-value systems (identity, VPN, email, production), vulnerabilities with known exploits, and issues that enable remote code execution or privilege escalation. Then enforce patch SLAs and track progress using consistent metrics so remediation is steady, not reactive.

SynScan combines attack surface monitoring and continuous security auditing to keep your inventory current, flag high-impact vulnerabilities early, and help you turn raw findings into a practical remediation plan.
