Deeper analysis
CVE-2023-24151 is a command injection vulnerability (CWE-77) affecting the TOTOLINK T8 router running firmware version V4.1.5cu. The flaw resides in the ip parameter processed by the recvSlaveCloudCheckStatus function, which accepts attacker-controlled input from an MQTT packet without adequate sanitization, enabling execution of arbitrary operating-system commands.
An unauthenticated attacker with network access can send a crafted MQTT packet to the device and obtain full control, including the ability to read, modify, or delete data and potentially pivot within the local network. The vulnerability carries a CVSS 3.1 base score of 9.8, reflecting its remote, low-complexity, no-privilege attack vector.
Public references consist of technical write-ups and proof-of-concept material hosted on GitHub; no vendor advisory or firmware patch addressing the issue is referenced in the available sources. The associated EPSS score has remained flat at 0.0784 with no material increase since disclosure.
