Summary
CVE-2024-57223 is a critical-severity Command Injection (CWE-77) vulnerability in Linksys E7350 Firmware. Its CVSS base score is 9.8 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Network Device CLI (T1059.008); ranked in the top 15.3% 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).
Threat & Defense at a Glance
Threat & Defense Details
Mitigating Controls (NIST 800-53 r5)AI
Directly prevents command injection by requiring validation and sanitization of the unsanitized ifname parameter in the apcli_wps_gen_pincode function.
Requires timely identification, reporting, and correction of the command injection flaw in the Linksys E7350 firmware to eliminate the vulnerability.
Vulnerability scanning would detect the command injection issue in the apcli_wps_gen_pincode function, enabling remediation before exploitation.
MITRE ATT&CK Enterprise TechniquesAI
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.
