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
A vulnerability, which was classified as problematic, has been found in Sichuan Yougou Technology KuERP up to 1.0.4. Affected by this issue is the function del_sn_db of the file /application/index/controller/Service.php. The manipulation of the argument file leads to path traversal: '../filedir'. The exploit has been disclosed to the public and may be used. VDB-252254 is the identifier assigned to this vulnerability. NOTE: The vendor was contacted early about this disclosure but did not respond in any way.

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

A path traversal vulnerability in KuERP up to v1.0.4 allows attackers to manipulate the 'file' argument in the del_sn_db function within /application/index/controller/Service.php. By using '../filedir' sequences, attackers can traverse directories and access or delete files outside the intended directory. The public exploit availability and CVSS 9.8 indicate this is likely exploitable without authentication.

MitigationImplement strict input validation on the file parameter to reject path traversal sequences (../ and similar). Consider using basename() to extract only the filename and validating against an allowed directory whitelist.

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 KuERP installation
    Locate the KuERP application directory. Check for the presence of the /application/index/controller/Service.php file which contains the vulnerable function.
    Affected if KuERP is installed and Service.php exists at /application/index/controller/Service.php
  2. Check KuERP version
    Inspect version files or configuration within the KuERP installation directory. Common locations include a version.php file, composer.json, or a config file displaying the version number.
    Affected if The installed version is 1.0.4 or lower (any version <= 1.0.4)
  3. Locate vulnerable function code
    Open /application/index/controller/Service.php and search for the 'del_sn_db' function definition.
    Affected if The del_sn_db function exists in Service.php and accepts a 'file' parameter without proper path traversal validation
  4. Verify path traversal vulnerability pattern
    Examine the del_sn_db function code to confirm it uses the 'file' parameter directly in file operations (such as file_exists, unlink, or file operations) without sanitizing '../' sequences or applying basename().
    Affected if The function uses the file parameter directly in file operations without validating for '../' path traversal sequences
  5. Check web server exposure
    Verify that the Service.php controller is accessible via the web server hosting the KuERP application.
    Affected if The KuERP web interface is publicly or internally accessible and the Service controller endpoint can be reached

A user is affected if they have KuERP version 1.0.4 or lower installed with the Service.php file present and the del_sn_db function accessible without proper path traversal validation on the file parameter.
