SuiteCRM is an open-source Customer Relationship Management (CRM) software application. A vulnerability in versions prior to 8.6.1 allows for Host Header Injection when directly accessing the `/legacy` route. Version 8.6.1 contains a patch for the issue.
SuiteCRM through 7.12.1 and 8.x through 8.0.1 allows Remote Code Execution. Authenticated users with access to the Scheduled Reports module can achieve this by leveraging PHP deserialization in the email_recipients property. By using a crafted request, they can create a malicious report, containing a PHP-deserialization payload in the email_recipients field. Once someone accesses this report, the backend will deserialize the content of the email_recipients field and the payload gets executed. Project dependencies include a number of interesting PHP deserialization gadgets (e.g., Monolog/RCE1 from phpggc) that can be used for Code Execution.
SuiteCRM before 7.12.2 and 8.x before 8.0.1 allows authenticated SQL injection via the Tooltips action in the Project module, involving resource_id and start_date.
