CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:HSummary
CVE-2023-36103 is a critical-severity Command Injection (CWE-77) vulnerability in Tenda Ac15 Firmware. Its CVSS base score is 9.8 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Command and Scripting Interpreter (T1059); ranked in the top 29% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.
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-2023-36103 is a command injection vulnerability (CWE-77) in the goform/SetIPTVCfg interface of Tenda AC15 routers running firmware V15.03.05.20. The flaw permits unauthenticated remote attackers to supply a crafted POST request that results in execution of arbitrary operating-system commands on the device.
An attacker with network access can leverage the issue without credentials or user interaction to achieve full control over the router, including the ability to read or modify configuration, intercept traffic, or pivot into attached networks. The vulnerability carries a CVSS 3.1 base score of 9.8, reflecting its critical severity and ease of exploitation over the network.
A publicly available proof-of-concept exploit for the issue has been posted on GitHub. The current and peak EPSS values are both 0.1280, indicating a stable moderate exploitation probability without a material rise after disclosure. No vendor advisory or patch information is referenced in the available sources.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Secure SDLC practices directly require input validation and neutralization that prevent command injection.
Runtime monitoring of software and data can detect anomalous command execution resulting from injection.
Identifying recorded vulnerabilities enables remediation of command-injection flaws before exploitation.

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.
Secure coding standards require proper escaping and parameterization of commands, directly eliminating CWE-77.
Security testing in development catches command-injection vulnerabilities before release.
Secure development life cycle mandates input validation and command construction practices that directly prevent command injection.
Application security requirements explicitly call for controls against injection flaws including command injection.
Secure architecture principles reduce the attack surface but do not prescribe the specific neutralization techniques needed.
Environment separation limits the blast radius of an exploited command injection but does not prevent the flaw itself.
