Successful exploitation of these vulnerabilities could allow an attacker to gain full access to the underlying operating system of the device or cause a denial-of-service condition.
The following versions of Korenix Jetwave, are affected:
3.2.1 IMPROPER NEUTRALIZATION OF SPECIAL ELEMENTS USED IN A COMMAND (βCOMMAND INJECTIONβ) CWE-77
Korenix JetWave 4200 Series 1.3.0 and JetWave 3000 Series 1.6.0 are vulnerable to command injection. An attacker could modify the file_name parameter to execute commands as root.
CVE-2023-23294 has been assigned to this vulnerability. A CVSS v3 base score of 8.8 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H).
3.2.2 IMPROPER NEUTRALIZATION OF SPECIAL ELEMENTS USED IN A COMMAND (βCOMMAND INJECTIONβ) CWE-77
Korenix Jetwave 4200 Series 1.3.0 and JetWave 3000 Series 1.6.0 are vulnerable to command injection via /goform/formSysCmd. An attacker could modify the sysCmd parameter to execute commands as root.
CVE-2023-23295 has been assigned to this vulnerability. A CVSS v3 base score of 8.8 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H).
3.2.3 UNCONTROLLED RESOURCE CONSUMPTION CWE-400
Korenix JetWave 4200 Series 1.3.0 and JetWave 3200 Series 1.6.0 are vulnerable to a possible denial-of-service condition via /goform/formDefault. When logged in, a user could issue a POST request so that the underlying binary exits. The web-service then becomes unavailable and cannot be accessed until a user reboots the device.
CVE-2023-23296 has been assigned to this vulnerability. A CVSS v3 base score of 6.5 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H).
