Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SI-10 Information Input Validation good match

prevent

SI-10 enforces input validation to neutralize untrusted data, directly preventing the improper neutralization leading to reflected XSS in SimpleCharm.

SI-15 Information Output Filtering good match

prevent

SI-15 requires output filtering and encoding of user inputs before web page generation, comprehensively mitigating reflected XSS script execution.

SI-2 Flaw Remediation good match

prevent

SI-2 mandates timely flaw remediation, including patching vulnerable SimpleCharm versions up to 1.4.3 affected by this XSS CVE.

NVD Description

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in kmfoysal06 SimpleCharm simplecharm allows Reflected XSS.This issue affects SimpleCharm: from n/a through <= 1.4.3.

Deeper analysisAI

CVE-2024-56056 is an Improper Neutralization of Input During Web Page Generation vulnerability, classified as Reflected Cross-site Scripting (CWE-79), in the SimpleCharm WordPress theme developed by kmfoysal06. This flaw affects SimpleCharm versions from n/a through 1.4.3.

Attackers can exploit this vulnerability remotely over the network (AV:N) with low complexity (AC:L), no privileges required (PR:N), but it requires user interaction (UI:R), such as clicking a malicious link. Successful exploitation changes scope (S:C) and allows low-impact effects on confidentiality, integrity, and availability (C:L/I:L/A:L), enabling arbitrary script execution in the context of the targeted user's browser.
