CVE-2024-57021
Published: 15 January 2025
Summary
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 12.3% 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
TOTOLINK X5000R firmware version V9.1.0cu.2350_B20230313 contains an OS command injection vulnerability (CWE-78) in the setWiFiScheduleCfg function. The flaw is triggered through the eHour parameter and carries a CVSS 3.1 score of 8.8, reflecting network attack vector, low complexity, and required low-privileged credentials.
An authenticated attacker with network access can supply crafted input to the affected parameter, resulting in arbitrary operating-system command execution on the device. Successful exploitation grants the attacker the ability to read, modify, or delete data and to disrupt device operation.
The EPSS score for this CVE rose from lower values to a peak of 0.0695 on 2025-12-11 before receding to the current 0.0338, indicating a period of increased exploitation interest after public disclosure. A detailed proof-of-concept is available in public repositories, while the vendor has not published an advisory or patch information in the referenced materials.
