Raw vector
CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:HCVSS and EPSS are reproduced from their sources (NVD, FIRST EPSS). Risk Priority is our own derived reading, not an NVD score.
Summary
CVE-2023-1162 is a high-severity Command Injection (CWE-77) vulnerability in Draytek Vigor 2960 Firmware. Its CVSS base score is 7.2 (High).
Operationally, ranked in the top 2% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2023-1162 is a command injection vulnerability, tracked under CWE-77, that affects the web management interface of the DrayTek Vigor 2960 router in firmware versions 1.5.1.4 and 1.5.1.5. The flaw resides in an unknown function within the mainfunction.cgi file, where unsanitized input to the password argument can be manipulated to execute arbitrary commands. The issue was assigned a CVSS v3.1 score of 7.2 and is explicitly noted as unsupported when assigned, applying only to products no longer maintained by the vendor.
An attacker with high privileges can exploit the vulnerability remotely over the network to inject and execute operating system commands, resulting in full compromise of confidentiality, integrity, and availability on the affected device. Public disclosure of the exploit code increases the feasibility of targeted attacks against exposed management interfaces.
No vendor patches or official mitigations are available because the affected firmware versions are unsupported. Security practitioners are advised to retire or isolate these devices, restrict administrative interface access, and migrate to currently supported DrayTek hardware.
The EPSS score rose from a low baseline to a peak of 0.4146 on 2026-01-13 before receding to the current value of 0.2432, indicating a measurable increase in exploitation interest after public disclosure.

Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.
A.8.25 mandates secure SDLC practices including secure coding guidelines, security requirements, checkpoints, testing (scans/penetration), and developer training that reduce command injection defects, but leaves a minority slice (e.g. incomplete implementation of those practices, outsourced development without full assurance, or post-SDLC changes) where the weakness can still arise and be exploitable.
Application security requirements explicitly call for controls against injection flaws including command injection.
A.8.27 mandates security-by-design principles (e.g. distrust external input, secure session control, data validation/sanitization, least privilege) and design reviews that can stop command injection from being introduced, but this is only a minority slice of CWE-77 because the weakness can still arise in code that bypasses those principles, in non-reviewed components, or in runtime injection vectors the architecture review does not reach.
Secure coding standards require proper escaping and parameterization of commands, directly eliminating CWE-77.
Security testing in development catches command-injection vulnerabilities before release.
Hardening callouts derived
DISA STIG baselines are authored against specific weaknesses. Where this CVE cites a broad weakness class, the mapping is not asserted at that abstraction (owner ruling, 2026-09-25: grade only at Base and below), so no rule is shown here rather than a rule shown against the wrong grain.
- No fine-grained STIG row for CWE-77, a class-level weakness, and none of its children carries one either.
