CVE-2020-15615: 
Control Web Panel vulnerability analysis and mitigation

A critical remote code execution vulnerability was discovered in CentOS Web Panel (cwp-e17.0.9.8.923) affecting the ajaxftpmanager.php component. The vulnerability (CVE-2020-15615) was disclosed on June 25, 2020, and allows remote attackers to execute arbitrary code without requiring authentication. The vulnerability received a CVSS score of 9.8, indicating critical severity (ZDI Advisory).

The vulnerability exists within the ajaxftpmanager.php component of CentOS Web Panel. The specific flaw stems from the lack of proper validation of user-supplied strings before they are used in system calls. When parsing the userLogin parameter, the application fails to properly sanitize user input, allowing command injection. 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 with network attack vector, low complexity, and no required privileges or user interaction (ZDI Advisory).

The vulnerability allows attackers to execute arbitrary code in the context of root on affected systems. This means an attacker can gain complete control over the target system, potentially leading to system compromise, data theft, or service disruption (ZDI Advisory).

Given the nature of the vulnerability, the primary mitigation strategy is to restrict interaction with the service to trusted machines only. This can be accomplished through firewall rules and whitelisting to ensure that only legitimate clients and servers with a procedural relationship to the service are permitted to communicate with it (ZDI Advisory).
