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
Slican NCP/IPL/IPM/IPU devices are vulnerable to PHP Function Injection. An unauthenticated remote attacker is able to execute arbitrary PHP commands by sending specially crafted requests to /webcti/session_ajax.php endpoint. This issue was fixed in version 1.24.0190 (Slican NCP) and 6.61.0010 (Slican IPL/IPM/IPU).

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

Slican NCP/IPL/IPM/IPU devices contain a PHP function injection vulnerability in the /webcti/session_ajax.php endpoint. An unauthenticated remote attacker can send specially crafted requests to execute arbitrary PHP commands on the affected device, achieving full remote code execution without any authentication credentials.

MitigationApply the vendor-supplied patches by upgrading Slican NCP devices to version 1.24.0190 and IPL/IPM/IPU devices to version 6.61.0010. If immediate patching is not feasible, implement network segmentation or firewall rules to restrict unauthorized access to the /webcti/ endpoint from untrusted networks.

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. Identify the Slican device model
    Access the device admin interface or check the device label/documentation to determine if it is an NCP, IPL 256, IPM 032, or IPU 14 model.
    Affected if The device is any of these four models and the model cannot be determined.
  2. Check the installed firmware version
    Log into the device web interface or use the device's admin panel to locate the firmware version information. For NCP devices, look for version under system settings. For IPL/IPM/IPU devices, check the firmware version in the device status or about section.
    Affected if The firmware version is below 1.24.0190 for NCP devices, or below 6.61.0010 for IPL/IPM/IPU devices.
  3. Verify if the webcti endpoint is exposed
    Attempt to access http://[device-ip]/webcti/ or http://[device-ip]/webcti/session_ajax.php from a browser or using curl. A 403 or 200 response indicates the endpoint is reachable.
    Affected if The /webcti/ endpoint responds with HTTP 200 or 403 (not a connection timeout or refused error), meaning it is accessible on the network.
  4. Confirm web interface authentication status
    Access the main login page of the device (typically / or /index.php) without providing credentials to see if authentication is required or if the interface is accessible.
    Affected if The web interface does not require authentication or allows unauthenticated access to certain endpoints including /webcti/.

A user is affected if they have a Slican NCP, IPL 256, IPM 032, or IPU 14 device running firmware below the specified version thresholds AND the /webcti/session_ajax.php endpoint is accessible from the network without authentication.

Upgrade available Upgrade to 1.24.0190 / 6.61.0010 or later
Fixed in 1.24.01906.61.0010
Interim mitigation

Apply the vendor-supplied patches by upgrading Slican NCP devices to version 1.24.0190 and IPL/IPM/IPU devices to version 6.61.0010. If immediate patching is not feasible, implement network segmentation or firewall rules to restrict unauthorized access to the /webcti/ endpoint from untrusted networks.

Recommended fix High confidence

Slican NCP firmware >= 1.24.0190 | Slican IPL/IPM/IPU firmware >= 6.61.0010

  1. Identify the specific Slican device model (NCP, IPL-256, IPM-032, or IPU-14)
  2. Check the current firmware version on the device
  3. For NCP devices: Upgrade firmware to version 1.24.0190 or later
  4. For IPL-256, IPM-032, or IPU-14 devices: Upgrade firmware to version 6.61.0010 or later
  5. After upgrading, verify the /webcti/session_ajax.php endpoint requires authentication
