SB2025032618 - Multiple vulnerabilities in CarlinKit CPC200-CCPA

Description

This security bulletin contains information about 4 vulnerabilities.

1) Missing Immutable Root of Trust in Hardware (CVE-ID: CVE-2025-2762)

CWE-ID: CWE-1326 - Missing Immutable Root of Trust in Hardware

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear

The vulnerability allows a local attacker to compromise the target system.

The vulnerability exists due to lack of a properly configured hardware root of trust within the configuration of the application system-on-chip (SoC). A local user can execute arbitrary code on the system with elevated privileges.

2) Improper Verification of Cryptographic Signature (CVE-ID: CVE-2025-2763)

CWE-ID: CWE-347 - Improper Verification of Cryptographic Signature

CVSSv4: CVSS:4.0/AV:P/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear

The vulnerability allows a local attacker to compromise the target system.

The vulnerability exists due to the lack of proper verification of a cryptographic signature within the handling of update packages on USB drives. An attacker with physical access can execute arbitrary code on the system.

3) Improper Verification of Cryptographic Signature (CVE-ID: CVE-2025-2764)

CWE-ID: CWE-347 - Improper Verification of Cryptographic Signature

CVSSv4: CVSS:4.0/AV:A/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Green

The vulnerability allows a remote attacker to compromise the target system.

The vulnerability exists due to the lack of proper verification of a cryptographic signature within the handling of update packages provided to update.cgi. A remote user on the local network can execute arbitrary code on the system.

4) Use of hard-coded credentials (CVE-ID: CVE-2025-2765)

CWE-ID: CWE-798 - Use of Hard-coded Credentials

CVSSv4: CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:N/VC:H/VI:L/VA:L/SC:N/SI:N/SA:N/E:U/U:Green

The vulnerability allows a remote attacker to gain full access to vulnerable system.

The vulnerability exists due to presence of hard-coded credentials within the configuration of the wireless hotspot. A remote attacker on the local network can access the affected system using the hard-coded credentials.
