Summary

CVE-2024-13862 is a high-severity Cross-site Scripting (CWE-79) vulnerability in S3Bubble S3Bubble-Amazon-Web-Services-Oembed-Media-Streaming-Support. Its CVSS base score is 7.1 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Malicious Link (T1204.001); ranked at the 34.9th 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 Malicious Link (T1204.001) and 2 other techniques. 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 addresses the lack of parameter escaping before output by requiring filtering of information outputs to prevent reflected XSS script injection.

SI-10 Information Input Validation good match

prevent

Mandates validation of unsanitized input parameters to block malicious payloads from being accepted and reflected in web pages.

SI-2 Flaw Remediation good match

prevent

Ensures timely remediation of the specific flaw in the S3Bubble WordPress plugin through identification, reporting, and correction of vulnerabilities.

MITRE ATT&CK Enterprise TechniquesAI

T1204.001 Malicious Link Execution

An adversary may rely upon a user clicking a malicious link in order to gain execution.

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.

T1539 Steal Web Session Cookie Credential Access

An adversary may steal web application or service session cookies and use them to gain access to web applications or Internet services as an authenticated user without needing credentials.

Why these techniques?

Reflected XSS enables malicious link delivery (T1204.001) for arbitrary browser script execution, directly facilitating browser session hijacking (T1185) and web session cookie theft (T1539) as explicitly described in the CVE impacts.

Deeper analysisAI

CVE-2024-13862 is a reflected cross-site scripting (XSS) vulnerability, classified under CWE-79, in the S3Bubble Media Streaming (AWS|Elementor|YouTube|Vimeo Functionality) WordPress plugin through version 8.0. The flaw arises because the plugin does not sanitize and escape a parameter before outputting it back in the page, enabling script injection. 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, low attack complexity, no required privileges, user interaction, and changed scope.

An unauthenticated attacker (PR:N) can exploit this remotely (AV:N) by crafting a malicious link or page that requires victim interaction (UI:R), such as clicking or viewing content. The reflected nature targets high-privilege users like administrators, allowing arbitrary script execution in their browser context. This could result in low-level impacts on confidentiality, integrity, and availability, such as stealing session cookies, performing unauthorized actions, or defacing pages on behalf of the victim.
