Title source: llm
STIX 2.1

Exploitation Summary

CVE-2022-1386 has been observed exploited in the wild (reported by VulnCheck KEV). EIP tracks 7 public exploits from researchers including ardzz, im-hanzou, zycoder0day. A Nuclei detection template is also available.

AI-analyzed exploit summary This is a functional proof-of-concept exploit for CVE-2022-1386, an unauthenticated SSRF vulnerability in Fusion Builder WordPress plugin versions prior to 3.6.2. The script automates the exploitation process by generating a fusion ID, crafting a malicious request, and sending it to the target to read arbitrary files or make internal HTTP requests.

Description

The Fusion Builder WordPress plugin before 3.6.2, used in the Avada theme, does not validate a parameter in its forms which could be used to initiate arbitrary HTTP requests. The data returned is then reflected back in the application's response. This could be used to interact with hosts on the server's local network bypassing firewalls and access control measures.
