CVE-2024-8352: Hypestudio Social Web Suite Path Traversal

CVE-2024-8352 Overview

CVE-2024-8352 is a directory traversal vulnerability in the Social Web Suite – Social Media Auto Post, Social Media Auto Publish plugin for WordPress. The flaw affects all versions up to and including 4.1.11 and resides in the download_log function. Unauthenticated attackers can read arbitrary files on the underlying server by manipulating file path parameters. Disclosed files can include WordPress configuration data, credentials, and other sensitive system information. The vulnerability is tracked under [CWE-22] (Improper Limitation of a Pathname to a Restricted Directory).

Critical Impact
Unauthenticated remote attackers can read arbitrary files on WordPress servers running Social Web Suite ≤ 4.1.11, exposing credentials stored in wp-config.php and other sensitive files.

Affected Products

Hypestudio Social Web Suite plugin for WordPress, all versions through 4.1.11
WordPress sites with the Social Media Auto Post / Auto Publish plugin installed and active
Hosting environments where the WordPress process has read access to sensitive system files

Technical Details for CVE-2024-8352

Vulnerability Analysis

The vulnerability exists in the download_log function of the Social Web Suite plugin. The function accepts a user-supplied file path parameter and serves the file contents in the HTTP response. The plugin fails to sanitize directory traversal sequences such as ../ before passing the value to file read operations. As a result, an attacker can escape the intended log directory and reference any file readable by the web server process.

Because the vulnerable endpoint does not require authentication, exploitation requires only network access to the WordPress site. Targeted files commonly include wp-config.php, which stores database credentials and authentication secrets, as well as /etc/passwd and other OS-level files. Successful disclosure of wp-config.php typically enables follow-on database compromise and full site takeover.

Root Cause

The root cause is missing input validation and path canonicalization in the download_log handler. The function trusts the user-controlled filename parameter and does not enforce that resolved paths remain inside the plugin's log directory. Reference implementation details are available in the WordPress Plugin Code Review.

Attack Vector

An attacker sends a crafted HTTP request to the WordPress site invoking the download_log action with a relative path that traverses outside the intended directory. No credentials, user interaction, or prior reconnaissance are required. The response returns the contents of the targeted file. An EPSS percentile of 87.7 indicates a higher-than-typical probability of exploitation attempts relative to other CVEs.

// Vulnerability description — no verified public proof-of-concept available.
// The download_log function in class-socialwebsuite-log.php passes an
// unsanitized user-supplied filename to file read APIs, allowing path
// traversal sequences (../) to reach arbitrary files on the server.

Detection Methods for CVE-2024-8352

Indicators of Compromise

HTTP requests to WordPress admin-ajax or plugin endpoints containing download_log combined with ../ or URL-encoded %2e%2e%2f sequences
Web server access logs showing successful 200 responses to requests referencing files such as wp-config.php, /etc/passwd, or .htaccess
Outbound connections from the WordPress host following suspicious log download requests, suggesting follow-on credential abuse

Detection Strategies

Inspect WordPress and web server logs for the download_log action parameter accompanied by directory traversal patterns
Deploy WAF signatures that block path traversal payloads on requests targeting the Social Web Suite plugin paths
Correlate file-read anomalies on the WordPress host with authentication failures or database access spikes that could indicate use of disclosed credentials

Monitoring Recommendations

Enable verbose access logging on the WordPress front-end and forward to a centralized analytics platform for path traversal pattern matching
Monitor reads of sensitive files (wp-config.php, key material, .env) by the web server user and alert on unexpected access
Track plugin version inventory across managed WordPress sites and alert when Social Web Suite versions ≤ 4.1.11 are present

How to Mitigate CVE-2024-8352

Immediate Actions Required

Update the Social Web Suite plugin to the version released in WordPress Plugin Changeset 3155593, which is the first version above 4.1.11
Rotate any secrets stored in wp-config.php, including database credentials, AUTH_KEY, and salts, if exposure is suspected
Audit web server access logs for prior exploitation attempts against the download_log endpoint

Patch Information

The vendor addressed the issue in the changeset published at WordPress Plugin Change Log. Additional vulnerability details are available in the Wordfence Vulnerability Report. Administrators should apply the latest plugin version through the WordPress plugin updater.

Workarounds

Deactivate and remove the Social Web Suite plugin until the patched version is deployed
Apply WAF rules that block requests containing ../, %2e%2e%2f, or absolute paths in parameters targeting the plugin
Restrict file system permissions for the web server user so it cannot read sensitive files outside the WordPress webroot
