What is CVE-2019-5009?

Vtiger CRM versions prior to Hotfix2 are susceptible to a file upload vulnerability that permits the uploading of files with 'php3' extension masquerading as PNG images. This occurs in the logo upload feature wherein an attacker can insert PHP code into an image file, achieving remote code execution by leveraging certain actions within the application. The flaw circumvents protections against dangerous file extensions, enabling unauthorized execution of server-side scripts. Specific files involved in this vulnerability include actions/CompanyDetailsSave.php and actions/UpdateCompanyLogo.php.

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
