Raw vector
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:H/A:NSummary
CVE-2024-57539 is a high-severity Command Injection (CWE-77) vulnerability in Linksys E8450 Firmware. Its CVSS base score is 8.2 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Command and Scripting Interpreter (T1059); ranked in the top 31% 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.
Linksys E8450 firmware version 1.2.00.360516 contains a command injection vulnerability (CWE-77) that can be triggered through the userEmail parameter. The flaw received a CVSS 3.1 score of 8.2, reflecting network attack vector, low attack complexity, and no requirements for authentication or user interaction, with impacts limited to confidentiality and high integrity.
An unauthenticated remote attacker can supply crafted input to the userEmail field and execute arbitrary operating-system commands on the device. Successful exploitation allows modification of device configuration or data while providing only limited visibility into other information, consistent with the reported impact metrics.
The associated EPSS score reached a peak of 0.0835 after disclosure, up from a lower baseline to the current value of 0.0554, indicating emerging exploitation interest. Public technical details are available in a GitHub repository describing the issue, though no vendor advisory or patch information is referenced in the supplied data.

Mitigating Controls (NIST 800-53 r5) AI
Developer testing and evaluation can discover command-construction flaws before deployment.
Input validation directly stops construction of commands from untrusted data containing special elements.
Secure engineering principles include proper neutralization and safe command construction practices.
Mitigating Controls (NIST CSF 2.0) AI
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.
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.
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.
