Summary

CVE-2024-57536 is a high-severity Command Injection (CWE-77) vulnerability in Linksys E8450 Firmware. Its CVSS base score is 8.0 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 23.1% 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 are NIST 800-53 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).

Deeper analysis

CVE-2024-57536 is a command injection vulnerability (CWE-77) affecting the Linksys E8450 router on firmware version v1.2.00.360516. The issue arises via the wizard_status parameter, allowing arbitrary command execution on the device.

The vulnerability carries a CVSS v3.1 base score of 8.0 (AV:A/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H). An attacker with adjacent network access (AV:A) and low privileges (PR:L) can exploit it with low complexity and no user interaction, resulting in high impacts to confidentiality, integrity, and availability in an unchanged scope.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SI-10 Information Input Validation good match
prevent

Directly and comprehensively prevents command injection by requiring input validation and error handling at entry points like the wizard_status parameter.

SI-2 Flaw Remediation good match
prevent

Mandates timely remediation of the specific command injection flaw in Linksys E8450 firmware version v1.2.00.360516.

AC-6 Least Privilege partial match
prevent

Reduces impact of successful command injection by enforcing least privilege on processes handling the wizard_status parameter.
