Deeper analysis
CVE-2024-56034 is an Improper Neutralization of Input During Web Page Generation vulnerability, classified as Reflected Cross-site Scripting (XSS) under CWE-79, in the WordPress plugin "Services updates for customers" (service-updates-for-customers) developed by Irshad A.Khan. This issue affects all versions of the plugin from n/a through 1.0 inclusive, with a CVSS v3.1 base score of 7.1 (AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:L).
The vulnerability can be exploited remotely over the network by unauthenticated attackers (PR:N) with low attack complexity (AC:L), requiring user interaction such as clicking a malicious link (UI:R). Successful exploitation enables script execution in the context of the targeted user's browser, with a changed scope (S:C) that allows limited impacts on confidentiality, integrity, and availability (C:L/I:L/A:L), such as session hijacking, data theft, or page manipulation for authenticated users like site administrators.
