Published: 10 January 2025
Summary
CVE-2024-57227 is a high-severity Command Injection (CWE-77) vulnerability in Linksys E7350 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 25.3% 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).
Deeper analysis
CVE-2024-57227 is a command injection vulnerability (CWE-77) in the Linksys E7350 router running firmware version 1.1.00.032. The flaw exists in the apcli_do_enr_pbc_wps function, where the ifname parameter fails to properly sanitize user input, enabling arbitrary command execution. Published on January 10, 2025, it 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), indicating high severity due to its potential for significant impact.
An attacker with adjacent network access and low privileges, such as those obtainable through an initial foothold on the local network, can exploit this vulnerability with low complexity and no user interaction required. Successful exploitation allows high-impact consequences across confidentiality, integrity, and availability, potentially granting full control over the affected router, including execution of arbitrary system commands.
Proof-of-concept details are documented in the GitHub repository at https://github.com/yanggao017/vuln/blob/main/Linksys/E7350/CI_4_apcli_do_enr_pbc_wps/README.md. No official vendor advisories or patches are referenced in the available information.
