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.
-
Confirm b2evolution CMS installationLocate b2evolution files by searching for characteristic directories like /b2evolution/ or /blogs/, or look for b2evolution-specific files such as /b2evolution/index.php, /b2evolution/inc/_core/_config.php, or other core b2evolution files in the web root.Affected if No b2evolution installation is found, then this CVE does not apply.
-
Identify b2evolution versionCheck the installed b2evolution version by examining version files (such as _version.php in the b2evolution root directory), or view the HTML source of any b2evolution page for a version comment in the meta tags.Affected if The installed version is exactly 4.1.3.
-
Locate viewfile.phpSearch for the file viewfile.php in the b2evolution installation directory, typically found in the root or in the /htsrv/ directory of the b2evolution web path.Affected if viewfile.php exists in the b2evolution installation.
-
Verify root parameter handling in viewfile.phpExamine the viewfile.php source code and look for the 'root' parameter usage, specifically checking if it is used directly in SQL queries without proper sanitization, prepared statements, or parameterized queries.Affected if The 'root' parameter is processed without sanitization or prepared statements and is used in SQL queries.
-
Check authentication requirement for viewfile.phpAttempt to access viewfile.php without logging in, or review the authentication logic at the beginning of viewfile.php to determine if unauthenticated access is possible.Affected if Unauthenticated access to viewfile.php is possible, though the CVE states authenticated users are required (this may indicate an even wider attack surface).
A user is affected if b2evolution CMS version 4.1.3 is installed, viewfile.php exists, and the 'root' parameter is handled without sanitization or prepared statements in SQL queries.

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 dataUpgrade to a patched version of b2evolution; if unavailable, implement prepared statements/parameterized queries for the root parameter in viewfile.php.
