CVE-2024-0194 is a vulnerability identified in the CodeAstro Internet Banking System version 1.0, specifically affecting the Profile Picture Handler component within the file pages_account.php. The vulnerability is classified as CWE-434, which corresponds to an Unrestricted File Upload flaw. This type of vulnerability allows an attacker to upload files without proper validation or restrictions, potentially enabling the upload of malicious files such as web shells or scripts. The vulnerability can be exploited remotely without user interaction, but requires some level of privileges (PR:L) on the system. The CVSS v3.1 base score is 6.3, indicating a medium severity level, with attack vector as network (AV:N), low attack complexity (AC:L), privileges required (PR:L), no user interaction (UI:N), unchanged scope (S:U), and impacts on confidentiality, integrity, and availability rated as low to medium (C:L/I:L/A:L). Although no public exploits are currently known to be in the wild, the vulnerability has been publicly disclosed, increasing the risk of exploitation. The unrestricted upload flaw in a banking system is particularly concerning because it could allow attackers to upload malicious payloads that might lead to unauthorized access, data leakage, or disruption of banking services. The lack of available patches at the time of disclosure further exacerbates the risk. Given the critical nature of internet banking systems and the sensitive financial data they handle, this vulnerability represents a significant security risk if left unmitigated.

For European organizations using the CodeAstro Internet Banking System, this vulnerability poses a serious threat to the confidentiality, integrity, and availability of sensitive financial data and banking operations. Successful exploitation could allow attackers to upload malicious files that might lead to remote code execution, unauthorized access to customer accounts, data exfiltration, or service disruption. This could result in financial losses, reputational damage, regulatory penalties under GDPR, and erosion of customer trust. The banking sector in Europe is heavily regulated and targeted by cybercriminals, making such vulnerabilities particularly impactful. Additionally, the medium CVSS score and the requirement for some privileges mean that insider threats or compromised accounts could be leveraged to exploit this flaw. The absence of patches means organizations must rely on compensating controls to mitigate risk. The potential for cascading effects, such as lateral movement within the banking infrastructure or use of the compromised system as a pivot point for broader attacks, further elevates the threat to European financial institutions.

1. Immediate implementation of strict file upload validation controls: enforce file type whitelisting, file size limits, and content inspection to prevent malicious files from being uploaded. 2. Restrict upload permissions to the minimum necessary user roles and enforce strong authentication and authorization mechanisms to reduce the risk of privilege abuse. 3. Deploy web application firewalls (WAFs) with custom rules to detect and block suspicious upload attempts targeting the Profile Picture Handler component. 4. Monitor logs and network traffic for unusual file upload activities or anomalies related to pages_account.php. 5. Isolate the file upload directory with strict filesystem permissions and disable execution rights to prevent uploaded files from being executed as code. 6. Conduct regular security assessments and penetration testing focused on file upload functionalities. 7. Engage with the vendor (CodeAstro) for timely patch releases and apply updates as soon as they become available. 8. Educate internal users and administrators about the risks associated with file uploads and enforce least privilege principles. 9. Consider implementing application-layer sandboxing or containerization for uploaded content to limit potential damage. These measures go beyond generic advice by focusing on specific controls tailored to the identified vulnerable component and its operational context within banking systems.
