Summary

CVE-2022-32092 is a critical-severity OS Command Injection (CWE-78) vulnerability in Dlink Dir-645 Firmware. Its CVSS base score is 9.8 (Critical).

Operationally, ranked in the top 4.0% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

Deeper analysis

D-Link DIR-645 firmware version 1.03 contains an OS command injection vulnerability (CWE-78) in the __ajax_explorer.sgi endpoint, where the QUERY_STRING parameter is processed without adequate sanitization. The flaw received a CVSS 3.1 score of 9.8, reflecting network-accessible exploitation with no required credentials or user interaction and full impact on confidentiality, integrity, and availability.

An unauthenticated attacker can supply a crafted QUERY_STRING value over the network to execute arbitrary operating-system commands on the device. Successful exploitation grants the attacker the ability to run code with the privileges of the web server process, enabling actions such as configuration changes, file manipulation, or pivoting into attached networks.

Public references point to a D-Link security bulletin page and a GitHub repository containing technical details of the issue. The EPSS score stands at 0.2247 with no material increase from an earlier lower value.
