CVE-2023-29802
Published: 14 April 2023
Summary
CVE-2023-29802 is a critical-severity Command Injection (CWE-77) vulnerability in Totolink X18 Firmware. Its CVSS base score is 9.8 (Critical).
Operationally, ranked in the top 5.3% 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 X18 firmware version V9.1.0cu.2024_B20220329 contains a command-injection flaw (CWE-77) in the setDiagnosisCfg function, where the ip parameter is passed to a system command without proper sanitization. The vulnerability carries a CVSS 3.1 score of 9.8, reflecting network attack vector, low complexity, and no required authentication or user interaction.
An unauthenticated remote attacker can supply a crafted ip value to the affected endpoint and execute arbitrary operating-system commands on the device. Successful exploitation grants full control over the router, enabling actions such as configuration changes, traffic interception, or persistence mechanisms.
Public references consist of technical write-ups hosted on Notion that demonstrate the injection vector; no vendor advisory or firmware patch information is included in the available sources. The associated EPSS score reached a peak of 0.2264 after disclosure before settling at the current value of 0.1490, indicating measurable post-publication exploitation interest.
