CVE-2022-1756

MEDIUM NUCLEI

Newsletter < 7.4.5 - Reflected Cross-Site Scripting via REQUEST_URI

Title source: llm
STIX 2.1

Exploitation Summary

CVE-2022-1756 has a Nuclei detection template available — see the Nuclei card below for the Shodan/FOFA recon queries.

Description

The Newsletter WordPress plugin before 7.4.5 does not sanitize and escape the $_SERVER['REQUEST_URI'] before echoing it back in admin pages. Although this uses addslashes, and most modern browsers automatically URLEncode requests, this is still vulnerable to Reflected XSS in older browsers such as Internet Explorer 9 or below.
