Successful exploitation of these vulnerabilities could allow an attacker to obtain read-only access to network configuration information and terminal configuration data.
The following Hughes Network Systems work streams are affected:
Credentials to access device configuration information stored unencrypted in flash memory. These credentials would allow read-only access to network configuration information and terminal configuration data.
CVE-2024-39278 has been assigned to this vulnerability. A CVSS v3.1 base score of 4.2 has been calculated; the CVSS vector string is (AV:P/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N).
A CVSS v4 score has also been calculated for CVE-2024-39278. A base score of 5.1 has been calculated; the CVSS vector string is (CVSS4.0/AV:P/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N).
Credentials to access device configuration were transmitted using an unencrypted protocol. These credentials would allow read-only access to network configuration information and terminal configuration data.
CVE-2024-42495 has been assigned to this vulnerability. A CVSS v3.1 base score of 6.5 has been calculated; the CVSS vector string is (AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N).
A CVSS v4 score has also been calculated for CVE-2024-42495. A base score of 7.1 has been calculated; the CVSS vector string is (CVSS4.0/AV:A/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N).
