Published: 03 February 2023
Summary
CVE-2023-24150 is a critical-severity Command Injection (CWE-77) vulnerability in Totolink T8 Firmware. Its CVSS base score is 9.8 (Critical).
Operationally, ranked in the top 5.0% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis
CVE-2023-24150 is a command injection vulnerability in TOTOLINK T8 routers running firmware V4.1.5cu. It occurs in the meshSlaveDlfw function, where the serverIp parameter accepts unsanitized input from MQTT packets, enabling execution of arbitrary operating-system commands (CWE-77).
An unauthenticated attacker with network access can send a crafted MQTT packet to trigger the flaw, achieving remote code execution with full read, write, and control impact on the device, consistent with the CVSS 9.8 rating.
Public proof-of-concept details are available in GitHub repositories, but no vendor advisories, patches, or mitigation steps are referenced in the supplied sources. The EPSS score remains at 0.1638 with no indicated change since disclosure.
