Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

prevent

Directly prevents command injection by requiring validation and sanitization of the unsanitized ifname parameter in the apcli_wps_gen_pincode function.

preventrecover

Requires timely identification, reporting, and correction of the command injection flaw in the Linksys E7350 firmware to eliminate the vulnerability.

detectrespond

Vulnerability scanning would detect the command injection issue in the apcli_wps_gen_pincode function, enabling remediation before exploitation.

MITRE ATT&CK Enterprise TechniquesAI

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.
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.
Why these techniques?

Command injection via the ifname parameter in the router's apcli_wps_gen_pincode function enables remote exploitation of a public-facing web application (T1190) and arbitrary command execution on the network device (T1059.008).

NVD Description

Linksys E7350 1.1.00.032 was discovered to contain a command injection vulnerability via the ifname parameter in the apcli_wps_gen_pincode function.

Deeper analysisAI

CVE-2024-57223 is a command injection vulnerability (CWE-77) affecting the Linksys E7350 router in version 1.1.00.032. The issue resides in the apcli_wps_gen_pincode function, where the ifname parameter fails to properly sanitize user input, allowing arbitrary command execution. Published on January 10, 2025, it carries a CVSS v3.1 base score of 9.8 (Critical), reflecting its network accessibility, low attack complexity, lack of required privileges or user interaction, and high impacts across confidentiality, integrity, and availability.

Remote attackers can exploit this vulnerability without authentication by sending crafted requests to the affected function. Successful exploitation grants attackers the ability to execute arbitrary commands on the router's underlying operating system, potentially leading to complete device compromise, data theft, persistent access, or use as a pivot point in the network.

Mitigation details and a proof-of-concept are documented in the GitHub advisory at https://github.com/yanggao017/vuln/blob/main/Linksys/E7350/CI_6_apcli_wps_gen_pincode/README.md. No official vendor patches or workarounds are specified in available information.
