Description

Adversaries may abuse scripting or built-in command line interpreters (CLI) on network devices to execute malicious command and payloads.

Security Summary

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.
