Successful exploitation of these vulnerabilities could provide attackers a way to traverse the file system to access files or directories that are outside of the restricted directory; allow the upload or transfer files of dangerous types that can be automatically processed within the productβs environment; allow an unauthorized access to an action or a resource; or allow a user to store dangerous data in a trusted database.
The following version of SmartPTT SCADA, an integrated voice and data dispatch software, is affected:
An attacker can inject JavaScript code into a specific parameter that can executed upon accessing the dashboard or the main page.
CVE-2021-43932 has been assigned to this vulnerability. A CVSS v3 base score of 9.0 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:H).
A low-authenticated user can access higher level administration authorization by issuing requests directly to the desired endpoints.
CVE-2021-43939 has been assigned to this vulnerability. A CVSS v3 base score of 8.8 has been calculated; the CVSS vector string is (AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H).
The backup and restore system does not adequately validate upload requests, enabling a malicious user to potentially upload arbitrary files.
CVE-2021-43934 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).
The backup and restore system does not adequately validate download requests, enabling malicious users to perform path traversal attacks and potentially download arbitrary files from the system.
CVE-2021-43930 has been assigned to this vulnerability. A CVSS v3 base score of 4.9 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:N/A:N).
