Vulnerability from fkie_nvd - Published: 2019-06-03 21:29 - Updated: 2026-06-17 02:12

Severity

9.8 (Critical) - CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

Summary

The WP Live Chat Support Pro plugin through 8.0.26 for WordPress contains an arbitrary file upload vulnerability. This results from an incomplete patch for CVE-2018-12426. Arbitrary file upload is achieved by using a non-blacklisted executable file extension in conjunction with a whitelisted file extension, and prepending "magic bytes" to the payload to pass MIME checks. Specifically, an unauthenticated remote user submits a crafted file upload POST request to the REST api remote_upload endpoint. The file contains data that will fool the plugin's MIME check into classifying it as an image (which is a whitelisted file extension) and finally a trailing .phtml file extension.

How durations are calculated

Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.

Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
