CVE-2025-13296: T-Soft E-Commerce CSRF Vulnerability

CVE-2025-13296 Overview

CVE-2025-13296 is a Cross-Site Request Forgery (CSRF) vulnerability affecting Tekrom Technology Inc. T-Soft E-Commerce platform. This web application vulnerability allows attackers to craft malicious requests that can be executed in the context of an authenticated user without their consent. The vulnerability has been assigned a CVSS 3.1 score of 5.4 (Medium severity) with a network-based attack vector requiring user interaction.

CSRF vulnerabilities in e-commerce platforms are particularly concerning as they can lead to unauthorized actions such as modifying user account details, initiating transactions, or changing security settings on behalf of legitimate users.

Critical Impact

Attackers can force authenticated users to perform unintended actions on the T-Soft E-Commerce platform, potentially leading to unauthorized data modification and information disclosure.

Affected Products

• T-Soft E-Commerce through version 28112025

Technical Details for CVE-2025-13296

Vulnerability Analysis

This Cross-Site Request Forgery vulnerability exists in the T-Soft E-Commerce platform due to insufficient validation of request origins and the absence of proper anti-CSRF tokens. The CVSS vector CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:N indicates that the attack can be launched remotely over the network with low complexity, requires no privileges but does require user interaction (such as clicking a malicious link or visiting a compromised page).

The vulnerability is classified under CWE-352 (Cross-Site Request Forgery), which describes the weakness where a web application does not sufficiently verify whether a well-formed, valid, consistent request was intentionally provided by the user who submitted the request.

With an EPSS score of 0.015% (2.258th percentile as of 2025-12-16), the current probability of exploitation in the wild is relatively low, though this should not diminish the importance of applying appropriate mitigations.

Root Cause

The root cause of this vulnerability lies in the T-Soft E-Commerce platform's failure to implement proper CSRF protection mechanisms. E-commerce applications handle sensitive operations including user authentication, order processing, and account management. Without proper request validation through anti-CSRF tokens or same-origin policy enforcement, the application cannot distinguish between legitimate user-initiated requests and forged requests from malicious sources.

Attack Vector

The attack vector for CVE-2025-13296 is network-based, requiring the attacker to trick an authenticated user into interacting with a malicious page or link. A typical attack scenario involves:

1. The attacker creates a malicious webpage containing hidden form elements or JavaScript that automatically submits requests to the vulnerable T-Soft E-Commerce application
2. The attacker distributes links to this malicious page via phishing emails, social media, or compromised websites
3. When an authenticated user visits the malicious page, their browser automatically sends requests to the T-Soft E-Commerce platform with the user's valid session cookies
4. The vulnerable application processes these forged requests as if they were legitimately initiated by the user

The vulnerability manifests through the application's state-changing endpoints that accept requests without validating their origin. Attackers can exploit this by embedding hidden forms or crafting URLs that perform unauthorized actions when triggered by victim users. For detailed technical information, refer to the security advisory at the Turkish National Cyber Incident Response Center (USOM).

Detection Methods for CVE-2025-13296

Indicators of Compromise

• Unusual account modifications or transactions occurring without user initiation
• Web server logs showing referrer headers from external untrusted domains for sensitive operations
• Multiple state-changing requests originating from the same user session in rapid succession
• User reports of unauthorized changes to account settings or order details

Detection Strategies

Organizations can implement the following detection strategies to identify potential CSRF exploitation attempts:

Web Application Firewall (WAF) Rules: Configure WAF rules to inspect HTTP request headers, particularly the Referer and Origin headers, flagging requests to sensitive endpoints that originate from external domains.

Log Analysis: Monitor web server access logs for patterns indicating CSRF attacks, such as state-changing POST requests with external or missing referrer headers.

User Behavior Analytics: Implement monitoring for unusual user activity patterns that may indicate account compromise through CSRF, including unexpected password changes, email address modifications, or transaction patterns.

Session Monitoring: Track user sessions for anomalous activity where actions are performed without corresponding navigation patterns within the application.

Monitoring Recommendations

Security teams should establish continuous monitoring for the T-Soft E-Commerce platform focusing on:

• Real-time alerting for sensitive operations performed with mismatched or absent origin headers
• Regular review of access logs for patterns consistent with CSRF attacks
• Integration with SIEM solutions to correlate potential CSRF indicators across multiple data sources
• Periodic security assessments to verify CSRF protections are functioning correctly

How to Mitigate CVE-2025-13296

Immediate Actions Required

• Implement anti-CSRF tokens (synchronizer tokens) for all state-changing operations
• Enable SameSite cookie attribute set to Strict or Lax for session cookies
• Validate Origin and Referer headers on server-side for sensitive requests
• Apply the principle of least privilege to minimize impact of potential CSRF exploitation
• Educate users about phishing risks and the importance of logging out after sessions

Patch Information

Organizations should monitor Tekrom Technology Inc. for official security patches addressing CVE-2025-13296. The vulnerability affects T-Soft E-Commerce versions through 28112025. For the latest security guidance, refer to the official advisory published by the Turkish National Cyber Incident Response Center (USOM) at https://www.usom.gov.tr/bildirim/tr-25-0421.

Contact Tekrom Technology Inc. support for information about available updates and patch availability for your specific deployment.

Workarounds

While awaiting an official patch, organizations can implement the following workarounds to reduce exposure:

Web Application Firewall Configuration: Deploy WAF rules that validate request origins and block suspicious cross-origin requests to sensitive endpoints.

Reverse Proxy Headers Validation: Configure reverse proxies or load balancers to reject requests to state-changing endpoints that lack proper origin headers.

Custom CSRF Protection Layer: If application modification is possible, implement a custom middleware layer that generates and validates CSRF tokens for form submissions and AJAX requests.

Session Timeout Reduction: Reduce session timeout values to minimize the window of opportunity for CSRF exploitation.

User Awareness: Instruct users to log out of the T-Soft E-Commerce platform after completing transactions and avoid clicking suspicious links while authenticated.

Administrators should test any workarounds thoroughly in a non-production environment before deployment to ensure they do not impact legitimate application functionality.
