CVE-2020-15613: 
Control Web Panel vulnerability analysis and mitigation

A critical vulnerability (CVE-2020-15613) was discovered in CentOS Web Panel cwp-e17.0.9.8.923, reported on January 28, 2020, and publicly disclosed on June 25, 2020. This vulnerability allows remote attackers to execute arbitrary code on affected installations without requiring authentication (Zero Day Initiative).

The vulnerability exists within ajax_admin_apis.php, specifically in the parsing of the line parameter. The process fails to properly validate user-supplied strings before using them in system calls. The vulnerability has been assigned a CVSS score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H), indicating critical severity. Successful exploitation allows attackers to execute code in the context of root (Zero Day Initiative).

The vulnerability enables remote attackers to execute arbitrary code with root privileges on affected systems. This level of access provides complete system compromise, potentially allowing attackers to control the entire server, access sensitive data, and perform any operation on the affected system (Zero Day Initiative).

The vulnerability requires no authentication to exploit, making it particularly dangerous. The attack can be performed remotely, requires low complexity, and needs no user interaction for successful exploitation (Zero Day Initiative).

As no patch was available at the time of disclosure, the primary mitigation strategy is to restrict interaction with the service to trusted machines only. This can be implemented through firewall rules and whitelisting to ensure that only legitimate clients and servers with procedural relationships to the service are permitted to communicate with it (Zero Day Initiative).
