CVE-2025-13119: Critical CSRF Vulnerability Exposes Simple E-Banking System

by

Overview

CVE-2025-13119 identifies a Cross-Site Request Forgery (CSRF) vulnerability present in Fabian Ros/SourceCodester Simple E-Banking System version 1.0. This flaw allows an attacker to potentially execute unauthorized actions on behalf of legitimate users, posing a significant security risk. The exploit is remotely triggerable and publicly available, making prompt mitigation essential.

Technical Details

The vulnerability exists due to insufficient protection against CSRF attacks within the Simple E-Banking System. Specifically, the application does not adequately validate the origin of requests. An attacker could craft a malicious HTML page or email containing a forged request that, when visited or clicked by an authenticated user, would be unknowingly executed by the system. This could potentially lead to actions like unauthorized fund transfers, account modification, or other sensitive operations depending on the application’s functionalities.

The affected part of the system is currently unknown, but a successful exploit allows remote manipulation. The fact that an exploit has been published means the attack is more easily reproducible and increases the risk exposure.

CVSS Analysis

Currently, a CVSS score and severity level have not been assigned for CVE-2025-13119. However, given the nature of CSRF vulnerabilities and the presence of a published exploit, the potential impact is considerable. A proper risk assessment needs to be performed on an impacted environment. Once a CVSS score is available, this section will be updated.

Possible Impact

The successful exploitation of CVE-2025-13119 can have severe consequences, including:

  • Unauthorized Fund Transfers: Attackers could transfer funds from user accounts without their consent.
  • Account Modification: User account details, such as contact information or passwords, could be altered, leading to account takeover.
  • Data Manipulation: Depending on the application’s functionality, attackers may be able to manipulate other data within the system.
  • Reputational Damage: A successful attack can severely damage the reputation of the banking system and the organization responsible for it.

Mitigation or Patch Steps

To mitigate the risk posed by CVE-2025-13119, the following steps are recommended:

  • Apply a Patch: The most effective solution is to apply a security patch released by Fabian Ros/SourceCodester, if available. Check the official SourceCodester website or support channels for updates.
  • Implement CSRF Tokens: Integrate CSRF tokens into all forms and requests that perform state-changing operations. These tokens should be unique per user session and validated on the server-side.
  • Use the SameSite Cookie Attribute: Configure cookies with the SameSite attribute set to Strict or Lax to prevent CSRF attacks originating from cross-site requests.
  • Input Validation: Implement robust input validation to prevent attackers from injecting malicious code into requests.
  • User Education: Educate users about the risks of clicking on suspicious links or opening attachments from untrusted sources.
