Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

prevent

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

prevent

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

prevent

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

MITRE ATT&CK Enterprise TechniquesAI

T1190 Exploit Public-Facing Application Initial Access
Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.
T1059.008 Network Device CLI Execution
Adversaries may abuse scripting or built-in command line interpreters (CLI) on network devices to execute malicious command and payloads.
Why these techniques?

Command injection via wizard_status in the Linksys router's web interface enables exploitation of a public-facing application (T1190) and facilitates command execution on the network device CLI (T1059.008).

NVD Description

Linksys E8450 v1.2.00.360516 was discovered to contain a command injection vulnerability via wizard_status.

Deeper analysisAI

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.
