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. The flaw is tracked under CWE-352 and impacts all releases through build 28112025. An attacker who convinces an authenticated user to visit a malicious page can trigger unwanted state-changing actions on the target application under that user's session. The Turkish national cyber authority USOM published the coordinated advisory under reference TR-25-0421.

Critical Impact
Attackers can force authenticated users to execute unintended actions in T-Soft E-Commerce, resulting in limited confidentiality and integrity impact against the targeted account.

Affected Products

Tekrom Technology Inc. T-Soft E-Commerce through 28112025
All prior T-Soft E-Commerce releases lacking anti-CSRF protections
Deployments exposing authenticated administrative or user endpoints to browser sessions

Technical Details for CVE-2025-13296

Vulnerability Analysis

The vulnerability stems from missing Cross-Site Request Forgery protections in state-changing HTTP requests handled by T-Soft E-Commerce. The application accepts authenticated requests without validating an unpredictable, per-session token bound to the user. An attacker hosts a crafted page that issues a forged request to the T-Soft application. When a victim with an active session visits that page, the browser automatically attaches session cookies, and the server executes the action as if the user initiated it.

The attack requires user interaction, and the scope remains unchanged. Successful exploitation results in limited confidentiality and integrity impact, with no direct availability consequence. Because T-Soft E-Commerce serves administrative and storefront functions, forged requests can modify account settings, cart state, or catalog data depending on the victim's role.

Root Cause

The root cause is the absence of anti-CSRF safeguards on sensitive endpoints. Effective mitigations include synchronizer tokens, double-submit cookies, SameSite=Lax or Strict cookie attributes, and origin or referer validation. T-Soft E-Commerce builds through 28112025 do not enforce these controls consistently, so any state-changing request can be replayed cross-origin.

Attack Vector

Exploitation is network-based and requires the victim to load attacker-controlled content while authenticated to a T-Soft E-Commerce instance. The attacker crafts an HTML form, image tag, or JavaScript fetch request targeting a vulnerable endpoint. No credentials or elevated privileges are needed by the attacker; the browser supplies the victim's cookies automatically. Refer to the USOM Notification TR-25-0421 for coordinated advisory details.

Detection Methods for CVE-2025-13296

Indicators of Compromise

Inbound POST or GET requests to T-Soft E-Commerce endpoints carrying an external Referer or Origin header
Server logs showing successful state changes without a corresponding authenticated navigation sequence
Unexpected account modifications, order changes, or configuration updates initiated by legitimate user sessions

Detection Strategies

Deploy Web Application Firewall rules that enforce origin and referer header validation for authenticated POST endpoints
Log and alert on state-changing HTTP requests missing an expected CSRF token parameter or header
Correlate user session activity with browser navigation events to identify off-path requests

Monitoring Recommendations

Monitor administrative panel activity for changes initiated from unexpected browsing contexts
Baseline typical Referer values for authenticated endpoints and alert on deviations
Review CDN and proxy logs for high volumes of cross-origin requests targeting T-Soft E-Commerce paths

How to Mitigate CVE-2025-13296

Immediate Actions Required

Contact Tekrom Technology to obtain a patched T-Soft E-Commerce release later than build 28112025
Restrict administrative access to trusted networks or VPN-only paths until patched
Instruct administrators to log out of the application after completing sessions

Patch Information

Tekrom Technology has not published a public patch identifier in the referenced advisories. Consult the Siber Güvenlik Notification TR-25-0421 and coordinate directly with the vendor to obtain a fixed build. Verify that the delivered release enforces per-session CSRF tokens on all state-changing endpoints.

Workarounds

Set session cookies with SameSite=Strict or SameSite=Lax and the Secure attribute to block cross-site cookie attachment
Deploy a reverse proxy rule that rejects requests to sensitive paths when the Origin header does not match the application host
Require re-authentication before executing high-impact actions such as password changes or order approvals

bash

# Nginx example: enforce Origin header on state-changing requests
map $http_origin $csrf_allowed {
    default 0;
    "https://your-tsoft-domain.example" 1;
}

server {
    location ~* ^/(admin|account|checkout)/ {
        if ($request_method = POST) {
            set $block "$csrf_allowed";
            if ($block = 0) { return 403; }
        }
        proxy_pass http://tsoft_backend;
    }
