Unrestricted Upload of File with Dangerous Type vulnerability in ELEXtensions ELEX WordPress HelpDesk & Customer Ticketing System elex-helpdesk-customer-support-ticket-system allows Upload a Web Shell to a Web Server.This issue affects ELEX WordPress HelpDesk & Customer Ticketing System: from n/a through <= 3.2.9.

The ELEX WordPress HelpDesk & Customer Ticketing System plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the ehcrmnewticketpost() function in all versions up to, and including, 3.3.1. This makes it possible for unauthenticated attackers to upload arbitrary files on the affected site's server which may make remote code execution possible.

The ELEX WordPress HelpDesk & Customer Ticketing System plugin for WordPress is vulnerable to Arbitrary File Upload in all versions up to, and including, 3.3.7 via the initMailPart function. This is due to insufficient file type validation when saving IMAP email attachments. This makes it possible for unauthenticated attackers to upload files that may be executable, which makes remote code execution possible.

The ELEX WordPress HelpDesk & Customer Ticketing System plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 3.3.9 via the 'form (specifically the attacker-controlled ticketlabel field inside the url-encoded form string)' parameter parameter. This is due to missing server-side authentication and the absence of a class allowlist on deserialization, with the only guard being a nonce publicly emitted on any page carrying the [wsdesksupport] shortcode. This makes it possible for unauthenticated attackers to execute code on the server. A successful exploit requires a single anonymous GET to any public page carrying the [wsdesksupport] shortcode to harvest the publicly emitted wsdesknonce value, after which a single unauthenticated POST completes the attack.

Subscriber SQL Injection in ELEX WooCommerce Advanced Bulk Edit Products, Prices & Attributes <= 1.5.3 versions.

The ELEX WordPress HelpDesk & Customer Ticketing System plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the factoryreset function in all versions up to, and including, 3.3.8 This makes it possible for unauthenticated attackers to delete arbitrary files on the server, which can easily lead to remote code execution when the right file is deleted (such as wp-config.php). This vulnerability is exploitable via a two-step chain: an unauthenticated attacker first stores an arbitrary ticketattachmentpath value by submitting a ticket through the nopriv ehcrmnewticketpost AJAX endpoint (whose nonce is publicly exposed via the [wsdesksupport] shortcode), then triggers the factoryreset routine via a GET request to wp-admin/admin.php?page=wsdeskfactoryreset, which is guarded only by isadmin() — a request-type check — rather than a capability check, causing unlink() to be called on the attacker-supplied path.

The ELEX WordPress HelpDesk & Customer Ticketing System plugin for WordPress is vulnerable to privilege escalation due to a missing capability check on the 'ehcrmagentadduser' AJAX action in all versions up to, and including, 3.2.6. This makes it possible for authenticated attackers, with Subscriber-level access and above, to create new administrative user accounts.

The ELEX WordPress HelpDesk & Customer Ticketing System plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 3.3.2. This is due to missing authorization checks on the ehcrmeditagent AJAX action. This makes it possible for authenticated attackers, with Contributor-level access and above, to escalate their WSDesk privileges from limited "Reply Tickets" permissions to full helpdesk administrator capabilities, gaining unauthorized access to ticket management, settings configuration, agent administration, and sensitive customer data.

The ELEX WooCommerce Dynamic Pricing and Discounts plugin for WordPress is vulnerable to unauthorized access of data due to a missing capability check on the elexdpexportrules() and elexdpimportrules() functions in all versions up to, and including, 2.1.7.

The ELEX WooCommerce Advanced Bulk Edit Products, Prices & Attributes plugin for WordPress is vulnerable to SQL Injection via the 'attributevaluefilter' parameter in all versions up to, and including, 1.4.9 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with Subscriber-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

The ELEX WooCommerce Google Shopping (Google Product Feed) plugin for WordPress is vulnerable to SQL Injection via the 'filetodelete' parameter in all versions up to, and including, 1.4.3 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with Administrator-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

The ELEX WordPress HelpDesk & Customer Ticketing System plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the ehcrmrestoredata() function in all versions up to, and including, 3.3.1. This makes it possible for authenticated attackers, with Subscriber-level access and above, to restore tickets.

The ELEX WordPress HelpDesk & Customer Ticketing System plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the 'ehcrmsettingsemptytrash' function in all versions up to, and including, 3.3.1. This makes it possible for authenticated attackers, with Subscriber-level access and above, to empty the ticket trash.

The ELEX WordPress HelpDesk & Customer Ticketing System plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the 'ehcrmsettingsrestoretrash' AJAX endpoint in all versions up to, and including, 3.3.1. This makes it possible for authenticated attackers, with Subscriber-level access and above, to restore all deleted tickets.

The ELEX WordPress HelpDesk & Customer Ticketing System plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the 'wpajaxehcrmsettingsemptyscheduledactions' AJAX Action in all versions up to, and including, 3.3.0. This makes it possible for authenticated attackers, with Subscriber-level access and above, to clear the scheduled triggers option.

The ELEX WordPress HelpDesk & Customer Ticketing System plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 3.2.9 via the 'ehcrmticketsingleviewclient' due to missing validation on a user controlled key. This makes it possible for authenticated attackers, with Subscriber-level access and above, to read the contents of all support tickets.

The ELEX WordPress HelpDesk & Customer Ticketing System plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the 'ehcrmremoveagent' function in all versions up to, and including, 3.3.1.
