Deeper analysis
TOTOLINK A7100RU running firmware version V7.4cu.2313_B20191024 contains a command-injection vulnerability tracked as CVE-2023-30053 and assigned CWE-78. The flaw received a CVSS 3.1 score of 9.8, reflecting network attackability without authentication or user interaction and full impact on confidentiality, integrity, and availability.
An unauthenticated attacker with network access can supply crafted input that results in arbitrary operating-system command execution on the device. Successful exploitation therefore grants an adversary the ability to read or modify configuration and data, install persistent malware, or disrupt device operation.
Public references consist of proof-of-concept material hosted on GitHub that demonstrates the injection vector. The associated EPSS score rose from a low baseline to a peak of 0.0508 on 2025-12-11 before receding to its current value of 0.0358, indicating a measurable but temporary increase in observed exploitation interest after disclosure.
