Title source: llm
STIX 2.1

Exploitation Summary

CVE-2021-24236 has a Nuclei detection template available — see the Nuclei card below for the Shodan/FOFA recon queries.

Description

The Imagements WordPress plugin through 1.2.5 allows images to be uploaded in comments, however only checks for the Content-Type in the request to forbid dangerous files. This allows unauthenticated attackers to upload arbitrary files by using a valid image Content-Type along with a PHP filename and code, leading to RCE.
