CVE-2024-33438 is a file upload vulnerability identified in CubeCart versions before 6.5.5. The flaw arises from insufficient validation of uploaded files, specifically allowing an authenticated user to upload a malicious .phar (PHP Archive) file. The .phar file format can contain PHP code that, when processed by the application, leads to arbitrary code execution on the server. This vulnerability is classified under CWE-434 (Unrestricted Upload of File with Dangerous Type). The vulnerability requires the attacker to have valid user credentials (authenticated user) and involves user interaction to upload the crafted file. The CVSS v3.1 score is 8.0, indicating high severity, with attack vector as network (remote), low attack complexity, privileges required, and user interaction needed. The impact includes full compromise of confidentiality, integrity, and availability of the affected system. Although no public exploits are currently known, the vulnerability poses a significant risk to CubeCart installations that have not been updated to version 6.5.5 or later. CubeCart is an e-commerce platform, so exploitation could lead to theft of customer data, manipulation of transactions, or server takeover.

The potential impact of CVE-2024-33438 is severe for organizations using vulnerable CubeCart versions. Successful exploitation allows attackers to execute arbitrary code remotely, which can lead to full system compromise. This threatens the confidentiality of sensitive customer and business data, including payment information and personal details. Integrity of the e-commerce platform can be undermined by altering product listings, prices, or transaction records. Availability may be affected if attackers deploy ransomware or disrupt services. The breach of trust and potential regulatory penalties could cause significant financial and reputational damage. Since CubeCart is used globally, organizations running outdated versions are at risk, especially those with limited security monitoring or patch management. The requirement for authentication limits the attack surface but does not eliminate risk, as attackers may leverage stolen credentials or weak authentication mechanisms.

To mitigate CVE-2024-33438, organizations should immediately upgrade CubeCart to version 6.5.5 or later, where the vulnerability is patched. If immediate patching is not feasible, implement strict file upload validation to block .phar files and other potentially dangerous file types at the web server or application firewall level. Enforce strong authentication controls, including multi-factor authentication, to reduce the risk of credential compromise. Monitor logs for suspicious file upload attempts and anomalous user behavior. Employ web application firewalls (WAFs) with rules targeting file upload vulnerabilities. Regularly audit user accounts and permissions to limit the number of users with upload privileges. Conduct security awareness training to reduce the risk of credential theft. Finally, maintain regular backups and incident response plans to quickly recover from potential compromises.
