CVE-2020-15625
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 disclose sensitive information 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_add_mailbox.php. When parsing the username parameter, the process does not properly validate a user-supplied string before using it to construct SQL queries. An attacker can leverage this vulnerability to disclose information in the context of root. Was ZDI-CAN-9729.
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 confidenceAn unauthenticated SQL injection vulnerability in the username parameter of ajax_add_mailbox.php in CentOS Web Panel allows remote attackers to construct malicious SQL queries and extract sensitive information from the database. The application fails to properly validate user-supplied input before using it in SQL queries.

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.
-
Identify the CentOS Web Panel versionLocate and retrieve the installed CWP version using the panel's version check mechanism or by inspecting the package/binary that provides the version information.Affected if The installed version is 0.9.8.923.
-
Locate the ajax_add_mailbox.php fileFind the file ajax_add_mailbox.php within the CWP web root directory structure. Common paths include /usr/local/cwpsrv/htdocs or /var/www/html/cwp/.Affected if The file exists in the CWP installation directory.
-
Inspect the username parameter handling in ajax_add_mailbox.phpOpen ajax_add_mailbox.php and examine how the username parameter is handled. Look for dynamic SQL query construction where the username value is directly concatenated into an SQL statement without proper escaping or use of prepared statements.Affected if The code directly incorporates the username parameter into a SQL query without using parameterized queries or input validation.
-
Confirm the SQL injection vulnerability existsSearch for SQL query patterns in the file that include the username parameter in the query string, particularly before the add_mailbox or similar database operation.Affected if The username parameter is used in a SQL query without sanitization or parameter binding.
A user is affected if they are running CentOS Web Panel version 0.9.8.923 and the ajax_add_mailbox.php file contains direct SQL query construction using the username 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 dataReplace dynamic SQL query construction with parameterized queries/prepared statements in ajax_add_mailbox.php, implement proper input validation on the username parameter, and apply vendor security patches if available.
