Published: 15 January 2025
Summary
CVE-2024-57020 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
Directly mitigates the OS command injection by requiring validation of the unsanitized sMinute parameter in setWiFiScheduleCfg.
Ensures timely firmware updates to remediate the specific flaw allowing arbitrary command execution on the TOTOLINK X5000R.
Restricts the sMinute parameter to valid inputs like numeric values 0-59, blocking malformed payloads used for command injection.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
OS command injection in router web management interface directly enables remote exploitation of public-facing apps and arbitrary Unix shell command execution.
NVD Description
TOTOLINK X5000R V9.1.0cu.2350_B20230313 was discovered to contain an OS command injection vulnerability via the "sMinute" parameter in setWiFiScheduleCfg.
Deeper analysisAI
CVE-2024-57020 is an OS command injection vulnerability (CWE-78) affecting the TOTOLINK X5000R router running firmware version V9.1.0cu.2350_B20230313. The flaw exists in the setWiFiScheduleCfg function, where the "sMinute" parameter fails to properly sanitize user input, allowing arbitrary command execution on the underlying operating system. This issue 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 high severity due to its network accessibility and potential for significant impact.
A remote attacker with low privileges, such as an authenticated user on the network, can exploit this vulnerability by sending a crafted request to the vulnerable endpoint. No user interaction is required, and the low attack complexity enables straightforward exploitation over the network. Successful exploitation grants the attacker high-level impacts on confidentiality, integrity, and availability, potentially allowing full compromise of the device, including execution of arbitrary commands, data exfiltration, or further lateral movement within the network.
Details on the vulnerability, including proof-of-concept exploitation steps, are documented in a GitHub repository at https://github.com/tiger5671/Vulnerabilities/blob/main/TOTOLINK%20X5000R/setWiFiScheduleCfg/setWiFiScheduleCfg.md. The vendor's website at https://www.totolink.net/ serves as the primary source for official advisories, though no specific patch or mitigation details are outlined in available references at this time. Security practitioners should monitor for firmware updates and apply network segmentation to limit exposure.
