Successful exploitation of these vulnerabilities could allow an attacker to gain remote code execution, sensitive data exfiltration, and complete takeover of the main multi-tenant cloud infrastructure.
The following versions of cnMaestro, a Network management system, are affected:
The affected On-Premise cnMaestro allows an unauthenticated attacker to access the cnMaestro server and execute arbitrary code in the privileges of the web server. This lack of validation could allow an attacker to append arbitrary data to the logger command.
CVE-2022-1357 has been assigned to this vulnerability. A CVSS v3 base score of 9.8 has been assigned; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H).
The affected On-Premise is vulnerable to data exfiltration through improper neutralization of special elements used in an SQL command. This could allow an attacker to exfiltrate and dump all data held in the cnMaestro database.
CVE-2022-1358 has been assigned to this vulnerability. A CVSS v3 base score of 5.9 has been assigned; the CVSS vector string is (AV:N/AC:H/PR:H/UI:N/S:U/C:H/I:H/A:N).
The affected On-Premise cnMaestro is vulnerable to a pre-auth data exfiltration through improper neutralization of special elements used in an SQL command. This could allow an attacker to exfiltrate data about other userβs accounts and devices.
CVE-2022-1361 has been assigned to this vulnerability. A CVSS v3 base score of 7.4 has been assigned; the CVSS vector string is (AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N).
The affected On-Premise cnMaestro is vulnerable to execution of code on the cnMaestro hosting server. This could allow a remote attacker to change server configuration settings.
CVE-2022-1360 has been assigned to this vulnerability. A CVSS v3 base score of 8.2 has been assigned; the CVSS vector string is (AV:N/AC:L/PR:H/UI:N/S:C/C:L/I:H/A:L).
The affected On-Premise cnMaestro is vulnerable inside a specific route where a user can upload a crafted package to the system. An attacker could abuse this user-controlled data to execute arbitrary commands on the server.
CVE-2022-1362 has been assigned to this vulnerability. A CVSS v3 base score of 5.0 has been assigned; the CVSS vector string is (AV:L/AC:L/PR:L/UI:R/S:U/C:N/I:H/A:N).
The affected On-Premise cnMaestro is vulnerable to an arbitrary file-write through improper limitation of a pathname to a restricted directory inside a specific route. If an attacker supplied path traversal charters (β¦/) as part of a filename, the server will save the file where the attacker chooses. This could allow an attacker to write any data to any file in the server.
CVE-2022-1359 has been assigned to this vulnerability. A CVSS v3 base score of 5.7 has been assigned; the CVSS vector string is (AV:N/AC:L/PR:L/UI:R/S:U/C:N/I:H/A:N).
The affected product is vulnerable to a local privilege escalation. By default, a user does not have root privileges. However, a user can run scripts as sudo, which could allow an attacker to gain root privileges when running user scripts outside allowed commands.
CVE-2022-1356 has been assigned to this vulnerability. A CVSS v3 base score of 7.1 has been assigned; the CVSS vector string is (AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:H).
