CVE-2026-63586

CriticalCVSS 9.8
Published: Translated: NVD NIST

Summary

The web-based management interface uses a modified uhttpd server with CGI shell scripts. The HTTP Basic Authentication username, taken directly from the Authorization header without sanitization, is inserted into a shell command string executed via the system() function. By submitting a specially crafted username containing shell metacharacters, an unauthenticated attacker with network access to the device can escape the command context and execute arbitrary commands with root privileges.

Risk Assessment

An attacker can gain full control over the device, potentially leading to system integrity compromise, data theft, or use of the device for further attacks.

Recommendation

Immediately update the device firmware to a version that includes a fix for this vulnerability and restrict network access to the management interface.
