CVE-2025-6131: Codeastro Food Ordering System XSS Vulnerability

CVE-2025-6131 Overview

CVE-2025-6131 is a stored cross-site scripting (XSS) vulnerability in CodeAstro Food Ordering System version 1.0. The flaw resides in the /admin/store/edit/ endpoint, where the POST request parameter handler fails to sanitize the Restaurant Name and Restaurant Address arguments. An authenticated attacker can inject arbitrary JavaScript that executes when other users render the affected admin views. The exploit has been publicly disclosed, but no evidence of exploitation in the wild has been reported. The issue is tracked under [CWE-79] and affects deployments running the vulnerable PHP CodeIgniter build.

Critical Impact
Authenticated attackers can persist malicious script payloads in the admin store editor, enabling session-context script execution against administrators who view the compromised record.

Technical Details for CVE-2025-6131

Vulnerability Analysis

The vulnerability is a stored cross-site scripting weakness [CWE-79] within the administrative store editor of CodeAstro Food Ordering System 1.0. The application accepts values submitted through the Restaurant Name and Restaurant Address POST parameters at /admin/store/edit/ without applying output encoding or input filtering. Submitted content is persisted to the backend datastore and later rendered directly into HTML contexts when administrators load the store management pages. Because the payload is stored, execution occurs on every subsequent view of the affected record, without requiring the attacker to be present. Exploitation requires an account with edit privileges on store records, which limits the pool of eligible attackers to authenticated users of the admin panel.

Root Cause

The root cause is missing neutralization of user-controlled input before it is embedded into HTML output. The /admin/store/edit/ handler stores the raw Restaurant Name and Restaurant Address field values, and the corresponding view template renders them without HTML entity encoding. This omission allows <script> tags and event-handler attributes to be interpreted by the browser as executable content rather than data.

Attack Vector

An authenticated attacker with access to the store edit form submits a crafted POST request containing JavaScript in the Restaurant Name or Restaurant Address fields. The payload is written to the database and executes in the browser of any user who subsequently views the store record. Attackers can leverage this to hijack admin sessions, perform actions in the admin context, or pivot to further compromise of the application. Technical proof-of-concept details are documented in the GitHub XSS Analysis Document and cataloged in VulDB #312600.

Detection Methods for CVE-2025-6131

Indicators of Compromise

Store records in the database whose Restaurant Name or Restaurant Address fields contain <script>, onerror=, onload=, or javascript: substrings.
Web server access logs showing POST requests to /admin/store/edit/ with URL-encoded HTML tag characters (%3Cscript%3E, %3Cimg).
Outbound HTTP requests from admin browsers to unfamiliar domains shortly after loading store management pages.

Detection Strategies

Deploy a web application firewall (WAF) rule set that inspects POST bodies to /admin/store/* for HTML tag and event-handler patterns.
Run database queries against the store table to identify stored values containing script markup or encoded equivalents.
Enable browser Content Security Policy (CSP) violation reporting to surface inline script execution originating from the admin interface.

Monitoring Recommendations

Audit admin account activity for unexpected edits to store records, particularly from accounts with recent password resets or new IP addresses.
Correlate admin session anomalies with reads of store edit pages to identify potential victim sessions.
Retain and review application error logs for template rendering exceptions that may indicate malformed injection attempts.

How to Mitigate CVE-2025-6131

Immediate Actions Required

Restrict access to the /admin/store/edit/ endpoint to trusted administrator accounts and enforce strong authentication.
Sanitize existing store records by stripping or HTML-encoding any script tags and inline event handlers already stored in the database.
Deploy a WAF policy that blocks HTML and JavaScript payloads submitted to admin form parameters.

Patch Information

No vendor patch has been published in the referenced advisories at the time of NVD listing. Consult the CodeAstro website and the GitHub XSS Analysis Document for the latest remediation guidance. Until an official fix is available, apply input validation and output encoding at the application layer.

Workarounds

Apply HTML entity encoding (htmlspecialchars with ENT_QUOTES in PHP) to all store field output in admin view templates.
Implement server-side input validation that rejects angle brackets and JavaScript URI schemes in the Restaurant Name and Restaurant Address fields.
Enforce a strict Content Security Policy that disallows inline scripts and restricts script sources to trusted origins.
Limit admin panel access using network-level controls such as IP allowlisting or VPN-only access.

bash

# Example nginx configuration to enforce CSP on the admin panel
location /admin/ {
    add_header Content-Security-Policy "default-src 'self'; script-src 'self'; object-src 'none'; base-uri 'self'" always;
    add_header X-XSS-Protection "1; mode=block" always;
    add_header X-Content-Type-Options "nosniff" always;
