The vulnerability identified as CVE-2024-50658 represents a critical server-side template injection flaw within AdPortal version 3.0.39. This issue resides in the updateuserinfo.html file where the shippingAsBilling and firstname parameters are processed without adequate input validation or sanitization. The flaw enables remote attackers to inject malicious template code that gets executed on the server, potentially leading to complete system compromise. The vulnerability stems from the application's improper handling of user-supplied data within template processing mechanisms, creating an attack vector that directly violates secure coding principles.
This server-side template injection vulnerability operates under the Common Weakness Enumeration CWE-74 category, specifically classified as improper neutralization of special elements used in a template engine. The attack surface is expanded through the manipulation of the shippingAsBilling parameter which likely controls conditional template rendering logic, and the firstname parameter that may be used in template variable substitution. When these parameters contain malicious template syntax, the application's template engine processes them as executable code rather than plain text input, allowing arbitrary command execution on the server. The vulnerability directly maps to ATT&CK technique T1059.008 for command and script injection, as attackers can leverage this flaw to execute arbitrary commands through template processing.
The operational impact of this vulnerability is severe and potentially catastrophic for affected systems. Remote attackers can execute arbitrary code with the privileges of the web application, potentially leading to full system compromise, data exfiltration, and persistence mechanisms. The vulnerability affects the updateuserinfo.html endpoint which suggests that any authenticated user or potentially unauthenticated attacker could exploit this issue depending on the application's access controls. Successful exploitation could result in unauthorized access to sensitive customer data, financial information, and system resources, while also providing attackers with a potential foothold for further lateral movement within the network infrastructure.
Mitigation strategies for CVE-2024-50658 must address both immediate remediation and long-term security improvements. The primary fix involves implementing proper input validation and sanitization for all parameters processed through template engines, ensuring that user-supplied data cannot be interpreted as template code. Organizations should apply the vendor's official patch or upgrade to a patched version of AdPortal immediately upon release. Additionally, implementing proper template engine security configurations, such as disabling template inheritance for user inputs, using secure template syntax, and implementing proper context encoding for template variables. Network segmentation, web application firewalls, and monitoring for suspicious template injection patterns should also be deployed to provide defense-in-depth measures. The vulnerability highlights the critical importance of secure template handling practices and proper input validation as outlined in OWASP Top Ten and NIST cybersecurity guidelines.
