CVE-2020-15432
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThis vulnerability allows remote attackers to execute arbitrary code on affected installations of CentOS Web Panel cwp-e17.0.9.8.923. Authentication is not required to exploit this vulnerability. The specific flaw exists within ajax_migration_cpanel.php. When parsing the filespace parameter, the process does not properly validate a user-supplied string before using it to execute a system call. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-9743.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceUnauthenticated command injection in CentOS Web Panel's ajax_migration_cpanel.php. The filespace parameter accepts unsanitized user input that gets passed to a system call, allowing remote attackers to execute arbitrary commands as root without authentication.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Verify CentOS Web Panel is installedCheck for the presence of CWP directories (typically /usr/local/cwpsrv/) or look for 'centos web panel' in installed packages via rpm -qa | grep -i cwpAffected if CWP is not installed on the system
-
Confirm the specific CWP versionRun: cat /usr/local/cwpsrv/version or check /usr/local/cwpsrv/version.txtAffected if The installed version is exactly 0.9.8.923
-
Locate the vulnerable ajax_migration_cpanel.php fileSearch for the file: find /usr/local/cwpsrv/htdocs -name 'ajax_migration_cpanel.php' 2>/dev/nullAffected if The file exists in the expected CWP directory structure
-
Check if the migration interface is accessibleAttempt a local curl to the endpoint: curl -s http://localhost:2030/admin/ajax_migration_cpanel.php (or verify the file is world-readable and the web service is running)Affected if The endpoint responds and the PHP file is executable by the web server user
-
Test for command injection vulnerabilitySend a crafted request with a test payload in the filespace parameter, e.g., curl -X POST 'http://localhost:2030/admin/ajax_migration_cpanel.php' -d 'filespace=test;id' and check if command output appears in the responseAffected if The server returns output from the injected command, confirming the vulnerability is exploitable
The system is affected if CentOS Web Panel version 0.9.8.923 is installed and the ajax_migration_cpanel.php migration endpoint is accessible, allowing unauthenticated command execution via the filespace parameter.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply vendor patch to CentOS Web Panel; if patch unavailable, restrict network access to the affected endpoint or disable the migration functionality until a fix is available.
