Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Improper neutralization of input during web page generation ('cross-site scripting') vulnerability in Gosoft Software Industry and Trade Ltd. Co. Proticaret E-Commerce allows Cross-Site Scripting (XSS), Reflected XSS. This issue affects Proticaret E-Commerce: from v5.0.0 before V 6.0.1767.1383.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

Reflected XSS vulnerability in Gosoft Proticaret E-Commerce allows attackers to inject malicious JavaScript through unsanitized user inputs that are immediately reflected back in web pages without proper output encoding. The vulnerability affects versions v5.0.0 through V 6.0.1767.1383, and can be exploited via crafted URLs or form submissions to steal session cookies, deface pages, or perform actions on behalf of authenticated users.

MitigationImplement context-aware output encoding for all user-supplied data rendered in HTML, add server-side input validation with allowlist filtering, and deploy Content Security Policy (CSP) headers to mitigate XSS execution. Upgrade to version V 6.0.1767.1383 or later if a patched release is available.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify the Gosoft Proticaret installation and version
    Locate the application version information in the product documentation, admin panel, or version file typically found in the installation directory or system information page
    Affected if The installed version is lower than 6.0.1767.1383 and the application handles user input that gets reflected in web pages
  2. Identify user input fields that get reflected in responses
    Review web application pages for query parameters, form inputs, or URL parameters that are echoed back in HTML responses without visible sanitization indicators
    Affected if User-supplied input from parameters like search queries, product IDs, or form fields is directly included in page output without encoding
  3. Test for reflected XSS by injecting a benign script payload
    Using a browser or testing tool, submit a test payload such as <script>alert(1)</script> in commonly used input fields and observe if the payload executes or appears unescaped in the response
    Affected if The injected script payload renders as executable JavaScript or appears as raw HTML/script tags in the response without being encoded or escaped
  4. Verify output encoding is absent in the response
    Inspect the HTTP response HTML source for specific input values to check if special characters like <, >, ", ' are converted to HTML entities (e.g., &lt;, &gt;, &quot;)
    Affected if Special characters in user input are passed through unchanged in the HTML response rather than being entity-encoded

A user is affected if running a version of Gosoft Proticaret E-Commerce below 6.0.1767.1383 and the application reflects unsanitized user input in web pages without proper HTML encoding.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Implement context-aware output encoding for all user-supplied data rendered in HTML, add server-side input validation with allowlist filtering, and deploy Content Security Policy (CSP) headers to mitigate XSS execution. Upgrade to version V 6.0.1767.1383 or later if a patched release is available.

Recommended fix Moderate confidence

Upgrade to Proticaret E-Commerce V 6.0.1767.1383 or later

  1. 1. Verify current Proticaret E-Commerce version by accessing the admin panel or checking system information.
  2. 2. If running version v5.0.0 through v6.0.1767.1382 (or any version before V 6.0.1767.1383), plan for upgrade.
  3. 3. Backup all database and configuration files before proceeding with upgrade.
  4. 4. Download the fixed version (V 6.0.1767.1383 or later) from the official Gosoft Software Industry and Trade Ltd. Co. vendor channels.
  5. 5. Follow vendor-provided upgrade instructions for Proticaret E-Commerce.
  6. 6. After upgrade, verify the application is functioning correctly.
  7. 7. Test that the previously vulnerable endpoint(s) no longer reflect untrusted input without proper sanitization.
