The vulnerability identified as CVE-2024-41454 represents a critical arbitrary file upload flaw within the Process Maker pm4core-docker 4.1.21-RC7 platform, specifically affecting the user interface login page logo upload functionality. This issue stems from inadequate input validation and sanitization mechanisms that fail to properly restrict file types and content, creating an exploitable entry point for malicious actors seeking to compromise the system. The vulnerability is particularly concerning as it targets the authentication interface, which serves as the primary gateway for user access to the platform's administrative functions and business process management capabilities.
The technical implementation of this flaw allows attackers to bypass standard security controls through a carefully crafted file upload operation that leverages the platform's permissive file type handling. When users attempt to upload custom logos through the login page interface, the system fails to perform adequate content verification or file type restriction checks. This absence of proper validation enables attackers to upload malicious PHP or HTML files that can be executed within the web server context, potentially leading to complete system compromise. The vulnerability operates under CWE-434 which specifically addresses the risk of uploading files that are automatically executed by a web server, making it a direct descendant of well-known file upload security weaknesses that have plagued web applications for decades.
The operational impact of this vulnerability extends far beyond simple unauthorized file placement, as it creates a persistent backdoor for attackers to execute arbitrary code on the target system. Successful exploitation could enable attackers to gain full administrative control over the Process Maker instance, potentially leading to data exfiltration, privilege escalation, and further lateral movement within the network infrastructure. The attack surface is particularly dangerous given that the vulnerability affects the login page functionality, which is frequently accessed and typically requires elevated privileges to modify. This presents an ideal scenario for attackers to establish persistent access while remaining undetected, as the uploaded malicious files could be disguised as legitimate branding elements.
Organizations utilizing Process Maker pm4core-docker 4.1.21-RC7 must implement immediate mitigations to address this vulnerability, including but not limited to restricting file upload capabilities, implementing strict file type validation, and deploying proper content security measures. The recommended approach involves configuring the web server to reject executable file types, implementing proper MIME type checking, and ensuring that uploaded files are stored in non-executable directories. Additionally, organizations should consider implementing web application firewalls and intrusion detection systems to monitor for suspicious upload activities. From an ATT&CK framework perspective, this vulnerability maps to T1505.003 (Web Shell) and T1059.007 (Command and Scripting Interpreter: PowerShell), representing the attack paths that adversaries would utilize to establish persistence and execute commands within the compromised environment. The vulnerability also aligns with the broader category of T1190 (Exploit Public-Facing Application) which encompasses attacks targeting web application interfaces and their associated file handling capabilities.
