A HTML injection vulnerability exists in Perfex CRM v3.3.1. The application fails to sanitize user input in the "Bill To" address field within the estimate module. As a result, arbitrary HTML can be injected and rendered unescaped in client-facing documents.

The authentication mechanism in Perfex CRM before 3.3.1 allows attackers to bypass login credentials due to insufficient server-side validation. By sending empty username and password parameters in the login request, an attacker can gain unauthorized access to user accounts, including administrative accounts, without providing valid credentials.

In Perfex Crm < 3.2.1, an authenticated attacker can send a crafted HTTP POST request to the affected uploadsalesfile endpoint. By providing malicious input in the relid parameter, combined with improper input validation, the attacker can bypass restrictions and upload arbitrary files to directories of their choice, potentially leading to remote code execution or server compromise.

HTML injection vulnerability in Perfex CRM v3.2.1 consisting of a stored HTML injection due to lack of proper validation of user input by sending a POST request in the parameters 'name' and 'clientid' at the endpoint '/projects/project/x'.

HTML injection vulnerability in Perfex CRM v3.2.1 consisting of a stored HTML injection due to lack of proper validation of user input by sending a POST request in the parameter 'expensename' at the endpoint '/expenses/expense'.

HTML injection vulnerability in Perfex CRM v3.2.1 consisting of a stored HTML injection due to lack of proper validation of user input by sending a POST request in the parameters 'name' and 'address' at the endpoint 'admin/leads/lead'.

HTML injection vulnerability in Perfex CRM v3.2.1 consisting of a stored HTML injection due to lack of proper validation of user input by sending a POST request in the parameter 'company' at the endpoint '/clients/client/x.

HTML injection vulnerability in Perfex CRM v3.2.1 consisting of a stored HTML injection due to lack of proper validation of user input by sending a POST request in the parameter 'name' at the endpoint '/subscriptions/create'.

HTML injection vulnerability in Perfex CRM v3.2.1 consisting of a stored HTML injection due to lack of proper validation of user input by sending a POST request in the parameters 'subject' at the endpoint 'knoewledgebase/article'.

Stored Cross-Site Scripting (XSS) in Perfex CRM chatbot before 3.3.1 allows attackers to inject arbitrary HTML/JavaScript. The payload is executed in the browsers of users viewing the chat, resulting in client-side code execution, potential session token theft, and other malicious actions. A different vulnerability than CVE-2024-8867.

A vulnerability was detected in CodeCanyon Perfex CRM up to 3.4.1. This affects the function Clients::project of the file application/controllers/Clients.php of the component Tenant Handler. The manipulation of the argument ID results in authorization bypass. The attack may be performed from remote. The exploit is now public and may be used.
