CVE-2022-28571
Published: 02 May 2022
Summary
CVE-2022-28571 is a critical-severity OS Command Injection (CWE-78) vulnerability in Dlink Dir-882 Firmware. Its CVSS base score is 9.8 (Critical).
Operationally, ranked in the top 4.8% 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-882 routers running firmware version DIR882A1_FW130B06 contain a command-injection flaw (CWE-78) inside the /usr/bin/cli binary. The issue received a CVSS 3.1 base score of 9.8, reflecting network attackability without credentials or user interaction and full confidentiality, integrity, and availability impact.
An unauthenticated attacker able to reach the device over the network can supply crafted input that results in arbitrary operating-system command execution. Successful exploitation therefore grants an adversary the ability to take complete control of the router, including traffic interception, persistence, or use of the device as an internal network pivot.
Public references point to a D-Link security-bulletin page and a GitHub repository that demonstrates the flaw; administrators should consult the vendor advisory for any available firmware updates or configuration mitigations. The CVE’s EPSS score has reached a peak of 0.1784 with a current value of 0.1737, indicating sustained but not sharply escalating exploitation interest since disclosure.
