Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 33.0th 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 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

Requires filtering of information prior to output, directly mitigating the reflected XSS by preventing unsanitized user input from executing malicious JavaScript in users' browsers.

SI-10 Information Input Validation good match

prevent

Enforces validation of user-supplied inputs like the vulnerable parameter, blocking malicious payloads before they are reflected in the page output.

SI-2 Flaw Remediation good match

prevent

Mandates timely flaw remediation, such as updating the WP-PManager plugin beyond version 1.2 to address the sanitization and escaping deficiency.

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.

T1059.007 JavaScript Execution

Adversaries may abuse various implementations of JavaScript for execution.

attack.mitre.org →

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 in public-facing WordPress plugin enables remote exploitation (T1190) to execute arbitrary JavaScript (T1059.007) in admin browser sessions, directly facilitating web session cookie theft (T1539).

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

NVD Description

The WP-PManager WordPress plugin through 1.2 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-2024-13875 is a reflected cross-site scripting (XSS) vulnerability affecting the WP-PManager WordPress plugin through version 1.2. The plugin fails to sanitize and escape a user-supplied parameter before outputting it back in the page, enabling attackers to inject and execute malicious JavaScript code in the context of the affected page. This issue is classified under CWE-79 (Cross-Site Scripting) and 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).

The vulnerability can be exploited remotely by any unauthenticated attacker with low attack complexity, though it requires user interaction such as clicking a malicious link. It targets high-privilege users like administrators, allowing the injected script to execute in their browser session upon interaction with the crafted payload. Successful exploitation could enable actions such as stealing session cookies, keystroke logging, or performing unauthorized operations on behalf of the victim.
