Successful exploitation of these vulnerabilities could allow an attacker to escalate privileges or remotely execute arbitrary code.
The following Delta Electronics products are affected:
3.2.1 IMPROPER ACCESS CONTROL CWE-284
An attacker could bypass the latest Delta Electronics InfraSuite Device Master (versions prior to 1.0.7) patch, which could allow an attacker to retrieve file contents.
CVE-2023-34316 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:H/I:N/A:N).
3.2.2 IMPROPER ACCESS CONTROL CWE-284
Delta Electronics InfraSuite Device Master versions prior to 1.0.7 contain improper access controls that could allow an attacker to alter privilege management configurations, resulting in privilege escalation.
CVE-2023-30765 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 DESERIALIZATION OF UNTRUSTED DATA CWE-502
Delta Electronics InfraSuite Device Master versions prior to 1.0.7 contains classes that cannot be deserialized, which could allow an attack to remotely execute arbitrary code.
CVE-2023-34347 has been assigned to this vulnerability. A CVSS v3 base score of 9.8 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H).
