CVE-2025-53755 (GCVE-0-2025-53755)

Vulnerability from cvelistv5 – Published: 2025-07-16 11:18 – Updated: 2025-07-16 18:52

Summary

This vulnerability exists in Digisol DG-GR6821AC Router due to storage of credentials and PINS without encryption in the device firmware. An attacker with physical access could exploit this vulnerability by extracting the firmware and reverse engineer the binary data to access the unencrypted data stored in the firmware of targeted device. Successful exploitation of this vulnerability could allow the attacker to gain unauthorized access to the network of the targeted device.

Severity ?

5.1 (Medium)

CVE-2025-53758 (GCVE-0-2025-53758)

Vulnerability from nvd – Published: 2025-07-16 11:29 – Updated: 2025-07-16 13:01

Summary

This vulnerability exists in Digisol DG-GR6821AC Router due to use of default admin credentials at its web management interface. An attacker with physical access could exploit this vulnerability by extracting the firmware and reverse engineer the binary data to access the hardcoded default credentials stored in the firmware of the targeted device. Successful exploitation of this vulnerability could allow the attacker to gain unauthorized access to the targeted device.

Severity ?

5.1 (Medium)

CVE-2025-53755 (GCVE-0-2025-53755)

Vulnerability from nvd – Published: 2025-07-16 11:18 – Updated: 2025-07-16 18:52

Summary

This vulnerability exists in Digisol DG-GR6821AC Router due to storage of credentials and PINS without encryption in the device firmware. An attacker with physical access could exploit this vulnerability by extracting the firmware and reverse engineer the binary data to access the unencrypted data stored in the firmware of targeted device. Successful exploitation of this vulnerability could allow the attacker to gain unauthorized access to the network of the targeted device.

Severity ?

5.1 (Medium)

CVE-2025-53754 (GCVE-0-2025-53754)

Vulnerability from nvd – Published: 2025-07-16 11:13 – Updated: 2025-07-16 15:52

Summary

This vulnerability exists in Digisol DG-GR6821AC Router due to hard-coded Root Access Credentials in system configuration of the device firmware. An attacker with physical access could exploit this vulnerability by extracting the firmware and analyzing the binary data to obtain the stored root access credentials. Successful exploitation of this vulnerability could allow the attacker to gain admin access to the targeted device.

Severity ?

5.1 (Medium)
