Q1What is this vulnerability? (Essence + Consequences)
🚨 **Essence**: Unauthenticated Sensitive Information Disclosure. 💥 **Consequences**: Attackers can steal site secrets without logging in.…
🛡️ **CWE**: CWE-200 (Information Exposure). 🔍 **Flaw**: The `includes` function in `redux-core/class-redux-core.php` registers AJAX actions that are predictable.…
🕵️ **Privileges**: None required (Unauthenticated). 📂 **Data Stolen**: List of active plugins & their versions. 🐍 **System Info**: Site's PHP version. 🧩 **Other**: Deterministic AJAX endpoints unique to the site.
Q5Is exploitation threshold high? (Auth/Config)
📉 **Threshold**: LOW. 🔓 **Auth**: No authentication needed. ⚙️ **Config**: Exploitation is easy because the AJAX action names are deterministic (MD5 hash based) and predictable using known salts.
Q6Is there a public Exp? (PoC/Wild Exploitation)
🔥 **Exploit**: YES. Multiple Python PoCs available on GitHub (e.g., `orangmuda`, `phrantom`, `c0ff33b34n`). 🌐 **Wild Exploitation**: High risk due to simplicity and widespread installation.…
🔍 **Check**: Scan for the specific AJAX endpoints generated by the MD5 hash logic. 📡 **Features**: Look for `admin-ajax.php` calls with predictable parameters derived from the site URL + `-redux` salt.…
🩹 **Fix**: Update the plugin to version **> 4.2.11**. 📢 **Official**: Redux.io and WordPress ecosystem recommend immediate patching. Check vendor updates for the patched release.
Q9What if no patch? (Workaround)
🚧 **Workaround**: If patching is delayed, restrict access to `admin-ajax.php` via WAF rules. 🚫 **Block**: Block requests containing the specific predictable AJAX action names derived from the site URL hash.…
⚡ **Priority**: HIGH. 📈 **Urgency**: Critical due to 1M+ affected sites and zero-auth requirement. 🏃 **Action**: Patch immediately to prevent reconnaissance by attackers. Don't wait!
