CVE-2022-28908
Published: 10 May 2022
Summary
CVE-2022-28908 is a critical-severity OS Command Injection (CWE-78) vulnerability in Totolink N600R Firmware. Its CVSS base score is 9.8 (Critical).
Operationally, ranked in the top 6.7% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis
TOTOLink N600R routers running firmware version V5.3c.7159_B20190425 contain an OS command injection vulnerability (CWE-78) in the web management interface. The flaw is triggered by unsanitized input supplied to the ipdoamin parameter of the /setting/setDiagnosisCfg endpoint, allowing arbitrary command execution on the underlying system.
Because the affected endpoint is reachable without authentication, an attacker with network access to the device can send a crafted HTTP request that results in immediate command execution. Successful exploitation yields full control over the router, including the ability to read or modify configuration, intercept traffic, or pivot to other hosts on the LAN.
Public proof-of-concept code demonstrating the injection has been posted to GitHub. The CVE carries a CVSS v3.1 score of 9.8 and an EPSS score that has reached approximately 0.11, indicating meaningful exploitability interest. No vendor advisory or firmware update addressing the issue is referenced in the available sources.
