Latest D-Link vulnerabilities
#
D-Link released a Security Announcement regarding vulnerabilities found within two of their DIR-X WiFi 6 routers (DIR-X5460 - AX5400, DIR-X4860 - EXO AX AX4800) and one of their non-US Mesh routers (COVRX1870 - AX1800).
CVE-2024-45694 is rated critical, with CVSS score of 9.8, and allows for an unauthenticated attacker to potentially execute arbitrary code.
CVE-2024-45695 is rated critical, with CVSS score of 9.8, and allows for an unauthenticated attacker to potentially execute arbitrary code.
CVE-2024-45696 is rated high, with CVSS score of 8.8, and allows for unauthorized access by an attacker.
CVE-2024-45697 is rated high, with CVSS score of 9.8, and allows for unauthorized access to the system by an attacker and the ability to execute arbitrary commands.
CVE-2024-45698 is rated high, with CVSS score of 8.8, and allows for unauthorized access to the operating system by an attacker and the ability to execute arbitrary commands.
What is the impact? #
Successful exploitation of the critical vulnerabilities through a stack overflow allows attackers to perform remote code execution (RCE) by sending malicious requests to vulnerable devices. The high severity vulnerabilities affect the target device's telnet service. CVE-2024-45696 allows for an attacker to forcibly enable telnet on the device, but must be on the same network as the device to log in through the telnet service. CVE-2024-45696, CVE-2024-45697, and CVE-2024-45698 allow for an attacker to log in to the telnet service using hard-coded credentials, if the service is enabled.
Are updates or workarounds available? #
D-Link has issued patches for each of the affected devices available for download in the Affected Models section of the announcement.
