CVE-2024-47349: WPMobile.App wpappninja XSS Vulnerability

CVE-2024-47349 Overview

CVE-2024-47349 is a reflected Cross-Site Scripting (XSS) vulnerability affecting the Amauri WPMobile.App WordPress plugin (wpappninja). The flaw stems from improper neutralization of user-supplied input during web page generation [CWE-79]. All versions of the plugin up to and including 11.50 are affected. An unauthenticated attacker can craft a malicious URL that, when clicked by a victim, executes arbitrary JavaScript in the victim's browser session. Successful exploitation can lead to session hijacking, credential theft, or redirection to attacker-controlled infrastructure. The vulnerability requires user interaction and impacts confidentiality, integrity, and availability within a changed security scope.

Critical Impact
Attackers can execute arbitrary JavaScript in a victim's browser through a crafted URL, enabling session theft and administrative account compromise on affected WordPress sites.

Affected Products

Amauri WPMobile.App (wpappninja) WordPress plugin
All versions from initial release through 11.50
WordPress sites running the vulnerable plugin

Technical Details for CVE-2024-47349

Vulnerability Analysis

The vulnerability is a reflected XSS flaw classified under [CWE-79]. The WPMobile.App plugin fails to properly sanitize or encode user-controlled input before reflecting it into HTML responses. When a victim visits a crafted link containing malicious JavaScript payloads, the plugin renders the input without adequate escaping, causing the browser to execute the payload in the site's origin context.

Because the security scope changes on exploitation, injected scripts can affect resources beyond the vulnerable component. Attackers commonly abuse this class of flaw to steal authentication cookies, perform actions on behalf of administrators, inject phishing content, or pivot to further compromise. The attack requires user interaction, typically delivered through phishing, malicious advertisements, or forum links.

EPSS data indicates a probability of 0.29% (20.62 percentile), reflecting current observed exploitation likelihood.

Root Cause

The root cause is missing or insufficient output encoding on input reflected into the plugin's response pages. Input values are echoed back into the HTML document without contextual escaping, allowing attacker-controlled data to be interpreted as executable script by the browser.

Attack Vector

The attack vector is network-based and requires no authentication. An attacker crafts a URL pointing to a vulnerable endpoint of the WPMobile.App plugin with a JavaScript payload embedded in a query parameter. Delivery relies on social engineering to induce a victim, ideally an authenticated administrator, to click the link. The malicious script executes under the WordPress site's origin, granting access to cookies, DOM content, and any authenticated session state.

The vulnerability manifests when reflected input is written into HTML without escaping. See the Patchstack Vulnerability Report for technical details.

Detection Methods for CVE-2024-47349

Indicators of Compromise

Web server access logs containing requests with <script>, javascript:, onerror=, or onload= patterns in query parameters targeting WPMobile.App endpoints
URL-encoded payloads such as %3Cscript%3E or %3Cimg directed at plugin routes
Unexpected outbound requests from browsers to attacker-controlled domains following visits to plugin URLs
Session cookies appearing in referrer headers or external log destinations

Detection Strategies

Inspect HTTP request logs for reflected parameters containing HTML tags or JavaScript event handlers targeting wpappninja plugin paths
Deploy Web Application Firewall (WAF) rules that flag XSS payload signatures in requests to WordPress plugin endpoints
Monitor for anomalous administrator account activity, such as new user creation or plugin installation from unusual IPs, following clicks on external links

Monitoring Recommendations

Enable verbose WordPress logging and forward events to a centralized SIEM for correlation
Alert on browser Content Security Policy (CSP) violation reports from WordPress origins
Track version telemetry for the WPMobile.App plugin across managed sites to identify unpatched deployments

How to Mitigate CVE-2024-47349

Immediate Actions Required

Upgrade the WPMobile.App plugin to a version later than 11.50 as soon as the vendor releases a fixed release
If no fix is available, deactivate and remove the WPMobile.App plugin from affected WordPress installations
Rotate administrator credentials and invalidate active sessions if suspicious activity is detected
Review recent administrator actions, user creations, and plugin installations for signs of exploitation

Patch Information

Refer to the Patchstack Vulnerability Report for the latest vendor patch status and remediation guidance. Administrators should apply the vendor-supplied update once released and confirm the plugin version is above 11.50.

Workarounds

Deploy a WAF rule set that blocks common XSS payload patterns targeting the plugin's request parameters
Enforce a strict Content Security Policy (CSP) that disallows inline scripts and restricts script sources to trusted origins
Restrict access to WordPress administrative interfaces by IP allowlist to limit exposure of privileged sessions
Train administrators to avoid clicking untrusted links while authenticated to WordPress
