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 · unedited
functions.php in Ragnarok Online Control Panel (ROCP) 4.3.4a allows remote attackers to bypass authentication by requesting account_manage.php with a trailing "/login.php" PHP_SELF value, which is not properly handled by the CHECK_AUTH function.

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 confidence

The CHECK_AUTH function in functions.php of Ragnarok Online Control Panel (ROCP) 4.3.4a fails to properly sanitize the PHP_SELF server variable when it contains a trailing '/login.php' path. This allows remote attackers to bypass authentication checks by crafting requests to account_manage.php with a manipulated PHP_SELF value.

MitigationApply input sanitization to PHP_SELF in the CHECK_AUTH function to validate and reject unexpected path segments, or upgrade to a patched version if available. Consider migrating to a supported application as ROCP appears to be abandoned.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Confirm ROCP installation and version
    Locate the control panel files and check for version identifier 4.3.4a in any version file, README, or installation manifest
    Affected if The installed version is exactly 4.3.4a
  2. Locate functions.php
    Find the functions.php file within the ROCP installation directory
    Affected if functions.php exists in the ROCP web root or include directory
  3. Examine CHECK_AUTH function
    Open functions.php and search for the CHECK_AUTH function definition
    Affected if The CHECK_AUTH function exists and handles authentication logic
  4. Inspect PHP_SELF handling
    Within CHECK_AUTH, look for code that uses $_SERVER['PHP_SELF'] and check if it properly sanitizes or validates the variable, especially for trailing '/login.php' strings
    Affected if PHP_SELF is used without proper sanitization of path segments like '/login.php'
  5. Verify affected endpoint exists
    Check if account_manage.php exists in the ROCP installation
    Affected if account_manage.php is present and accessible

A user is affected if ROCP version 4.3.4a is installed with a vulnerable functions.php where CHECK_AUTH fails to sanitize PHP_SELF, allowing the authentication bypass to succeed.

Mitigation

Apply input sanitization to PHP_SELF in the CHECK_AUTH function to validate and reject unexpected path segments, or upgrade to a patched version if available. Consider migrating to a supported application as ROCP appears to be abandoned.
