CVE-2026-19412
Hardcoded Credentials Vulnerability in CP Plus CP-XR-DE21-S Router
This vulnerability exists in the CP Plus CP-XR-DE21-S Router due to the presence of hardcoded HTTP Digest authentication credentials in the firmware that are identical across all devices running the affected firmware. An attacker with access to the local network could exploit this vulnerability by obtaining the hardcoded authentication information from the firmware.
Successful exploitation of this vulnerability could allow the attacker to gain unauthorized administrative access and perform privileged operations on the targeted device.
