CVE-2024-57021 is a high-severity OS Command Injection (CWE-78) vulnerability in Totolink X5000R Firmware. Its CVSS base score is 8.8 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 14.5% 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
SI-2 requires timely identification, reporting, and patching of known flaws like the OS command injection in setWiFiScheduleCfg, directly eliminating the vulnerability through firmware remediation.
SI-10 mandates validation and sanitization of user inputs such as the eHour parameter, preventing arbitrary OS command injection in the WiFi scheduling function.
RA-5 provides vulnerability scanning to detect the presence of CVE-2024-57021 in TOTOLINK X5000R firmware, enabling proactive remediation.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
OS command injection (CWE-78) in public-facing router web function directly enables RCE via unsanitized input, mapping to T1190 for initial exploitation and T1059.004 for resulting Unix shell command execution on the device.
NVD Description
TOTOLINK X5000R V9.1.0cu.2350_B20230313 was discovered to contain an OS command injection vulnerability via the "eHour" parameter in setWiFiScheduleCfg.
Deeper analysisAI
CVE-2024-57021, published on 2025-01-15, is an OS command injection vulnerability (CWE-78) affecting the TOTOLINK X5000R router on firmware version V9.1.0cu.2350_B20230313. The issue resides in the setWiFiScheduleCfg function, where the "eHour" parameter fails to properly sanitize user input, enabling attackers to inject and execute arbitrary operating system commands.
The vulnerability carries a CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H), indicating network accessibility with low attack complexity. Exploitation requires low privileges, such as those of an authenticated user, and no user interaction. Attackers can achieve high impacts on confidentiality, integrity, and availability, potentially resulting in full router compromise through remote code execution.
