Overview
CVE-2025-13119 describes a Cross-Site Request Forgery (CSRF) vulnerability found in Fabian Ros/SourceCodester Simple E-Banking System version 1.0. This flaw allows a remote attacker to potentially execute unauthorized actions on behalf of legitimate users, such as initiating forced withdrawals, if they can trick a user into clicking a malicious link or visiting a compromised website. The vulnerability has been published and an exploit is available, making it a significant security concern for deployments of this system.
Technical Details
The vulnerability resides in an unspecified part of the Simple E-Banking System 1.0. By crafting a malicious HTTP request that exploits the lack of CSRF protection, an attacker can force a logged-in user’s browser to send unauthorized requests to the application. This is typically achieved by embedding the malicious request within an <img> tag, <iframe>, or a simple link that a user might inadvertently click. The specific function vulnerable is likely related to actions such as fund transfers or account management.
CVSS Analysis
The Common Vulnerability Scoring System (CVSS) score for CVE-2025-13119 is 4.3, which is classified as MEDIUM severity. The CVSS vector is likely something like CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N. This score reflects the following:
- Attack Vector (AV:N): Network – The attack can be launched remotely over the network.
- Attack Complexity (AC:L): Low – The attack is relatively easy to execute.
- Privileges Required (PR:N): None – No privileges are required to exploit the vulnerability.
- User Interaction (UI:R): Required – User interaction is required (e.g., clicking a link).
- Scope (S:U): Unchanged – The vulnerability only affects the vulnerable component.
- Confidentiality Impact (C:N): None – There is no impact to data confidentiality.
- Integrity Impact (I:L): Low – There is a limited impact on data integrity. An attacker can modify some data.
- Availability Impact (A:N): None – There is no impact to system availability.
Possible Impact
A successful CSRF attack can have several negative consequences:
- Unauthorized Transactions: Attackers can initiate unauthorized fund transfers from a user’s account.
- Account Manipulation: They might be able to modify account settings or perform other actions on behalf of the user.
- Reputational Damage: Compromised accounts and unauthorized actions can damage the reputation of the Simple E-Banking System.
Mitigation or Patch Steps
To mitigate the risk posed by CVE-2025-13119, the following steps are recommended:
- Implement CSRF Protection: The most effective solution is to implement robust CSRF protection mechanisms. This typically involves adding a unique, unpredictable token to each form and request, and verifying this token on the server-side.
- Input Validation and Sanitization: Ensure all user inputs are properly validated and sanitized to prevent injection attacks that might aid in exploiting the CSRF vulnerability.
- Upgrade to a Patched Version: If a patched version of Simple E-Banking System 1.0 becomes available, upgrade immediately. This is the most direct way to address the vulnerability. Contact the vendor, Fabian Ros/SourceCodester, for information on patches.
- User Education: Educate users about the risks of clicking on suspicious links or visiting untrusted websites.
