Deeper analysis
CVE-2022-28584 is a command injection vulnerability, tracked under CWE-78, that affects the setWiFiWpsStart interface of the TOTOLINK A7100RU router running firmware version 7.4cu.2313_b20191024. The flaw permits an unauthenticated remote attacker to supply a crafted payload that results in arbitrary command execution on the device, reflected in its CVSS 3.1 base score of 9.8.
An attacker with network access can exploit the issue without authentication or user interaction by sending a malicious request directly to the affected interface, achieving full control over the router including the ability to read, modify, or delete data and potentially pivot to other devices on the network.
Public references consist of proof-of-concept repositories that demonstrate the injection vector; no vendor advisory or patch information is included in the supplied references. The associated EPSS score has remained in a moderate range with a peak of 0.2031 and a current value of 0.1871.
