Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability in Tips and Tricks HQ, Ruhul Amin, Josh Lobe Simple Download Monitor allows Blind SQL Injection. This issue affects Simple Download Monitor: from n/a through 3.9.25.

The Freemius SDK, as used by hundreds of WordPress plugin and theme developers, was vulnerable to Cross-Site Request Forgery and Information disclosure due to missing capability checks and nonce protection on the _get_debug_log, _get_db_option, and the _set_db_option functions in versions up to, and including 2.4.2. Any WordPress plugin or theme running a version of Freemius less than 2.4.3 is vulnerable.

The Simple Download Monitor WordPress plugin before 3.9.5 allows users with a role as low as Contributor to download any file on the web server (such as wp-config.php) via a path traversal vector.

The Simple Download Monitor WordPress plugin before 3.9.9 does not enforce nonce checks, which could allow attackers to perform CSRF attacks to 1) make admins export logs to exploit a separate log disclosure vulnerability (fixed in 3.9.6), 2) delete logs (fixed in 3.9.9), 3) remove thumbnail image from downloads

The Simple Download Monitor WordPress plugin before 3.9.11 could allow users with a role as low as Contributor to perform Stored Cross-Site Scripting attack via 1) "color" or "css_class" argument of sdm_download shortcode, 2) "class" or "placeholder" argument of sdm_search_form shortcode.

The Simple Download Monitor WordPress plugin before 3.9.5 does not escape the 1) sdm_active_tab GET parameter and 2) sdm_stats_start_date/sdm_stats_end_date POST parameters before outputting them back in attributes, leading to Reflected Cross-Site Scripting issues

The Simple Download Monitor WordPress plugin before 3.9.6 allows users with a role as low as Contributor to remove thumbnails from downloads they do not own, even if they cannot normally edit the download.

The Simple Download Monitor WordPress plugin before 3.9.5 does not escape the "File Thumbnail" post meta before outputting it in some pages, which could allow users with a role as low as Contributor to perform Stored Cross-Site Scripting attacks. Given the that XSS is triggered even when the Download is in a review state, contributor could make JavaScript code execute in a context of a reviewer such as admin and make them create a rogue admin account, or install a malicious plugin

The Simple Download Monitor WordPress plugin before 3.9.6 saves logs in a predictable location, and does not have any authentication or authorisation in place to prevent unauthenticated users to download and read the logs containing Sensitive Information such as IP Addresses and Usernames

SQL injection vulnerability in Simple Download Monitor 3.8.8 and earlier allows remote attackers to execute arbitrary SQL commands via a specially crafted URL.
