Summary

CVE-2024-13884 is a high-severity Cross-site Scripting (CWE-79) vulnerability in Rivercitygraphix Limit Bio. Its CVSS base score is 7.1 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 25.0th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-15 (Information Output Filtering).

Threat & Defense at a Glance

What attackers do: exploitation maps to Exploit Public-Facing Application (T1190) and 1 other technique. What defenders deploy: see the NIST 800-53 controls recommended below.

Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SI-15 Information Output Filtering good match

prevent

Directly mitigates reflected XSS by filtering and encoding plugin output to neutralize malicious scripts in the unsanitized parameter.

SI-10 Information Input Validation good match

prevent

Validates user inputs to the plugin parameter, preventing malicious JavaScript payloads from being accepted and reflected.

SI-2 Flaw Remediation good match

prevent

Remediates the flaw in the Limit Bio WordPress plugin through timely patching to implement proper sanitization and escaping.

MITRE ATT&CK Enterprise TechniquesAI

T1190 Exploit Public-Facing Application Initial Access

Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.

T1185 Browser Session Hijacking Collection

Adversaries may take advantage of security vulnerabilities and inherent functionality in browser software to change content, modify user-behaviors, and intercept information as part of various browser session hijacking techniques.

Why these techniques?

Reflected XSS in public-facing WordPress plugin enables network exploitation (T1190) and arbitrary JS execution leading to browser session hijacking (T1185).

Confidence: HIGH · MITRE ATT&CK Enterprise v19.0

NVD Description

The Limit Bio WordPress plugin through 1.0 does not sanitise and escape a parameter before outputting it back in the page, leading to a Reflected Cross-Site Scripting which could be used against high privilege users such as admin

Deeper analysisAI

CVE-2024-13884 is a reflected cross-site scripting (XSS) vulnerability affecting the Limit Bio WordPress plugin through version 1.0. The flaw arises because the plugin does not sanitize and escape a parameter before outputting it back in the page, enabling CWE-79: Improper Neutralization of Input During Web Page Generation. It carries 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), indicating high severity due to network accessibility and scope change.

Unauthenticated attackers (PR:N) can exploit this over the network with low attack complexity, though it requires user interaction (UI:R). By crafting a malicious payload in the vulnerable parameter and tricking a high-privilege user, such as an admin, into accessing a malicious link or page, the attacker can execute arbitrary JavaScript in the victim's browser context. This may result in low-level impacts on confidentiality, integrity, and availability, such as session hijacking or unauthorized actions performed as the targeted user.
