CVE-2024-2727
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 · uneditedHTML injection vulnerability affecting the CIGESv2 system, which allows an attacker to inject arbitrary code and modify elements of the website and email confirmation message.
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 confidenceHTML injection vulnerability in CIGESv2 allows attackers to inject arbitrary HTML/script code through unsanitized input fields, potentially modifying website content and email confirmation messages.

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 checksWork through these to decide whether this CVE applies to you.
-
Confirm CIGESv2 versionLocate the CIGESv2 installation directory and check for version files, about page, or admin panel that displays the software version. Common paths include version.info, CHANGELOG files, or the system administration interface.Affected if The installed version is exactly 2.0 (Atisoluciones Ciges = 2.0)
-
Identify user input formsBrowse the CIGESv2 web application and enumerate all forms that accept user input, including registration forms, contact forms, profile editing fields, search boxes, and any field that handles data submitted for email confirmation messages.Affected if The application contains form fields that accept user-supplied data without visible sanitization indicators
-
Check for output encoding in form handlersExamine the server-side code handling form submissions (PHP, ASP, or other backend files in the CIGESv2 installation) for functions that handle the submitted data before rendering in web pages or embedding in emails. Look for absence of sanitization functions like htmlspecialchars, strip_tags, or similar encoding methods.Affected if Form handler code does not perform output encoding or input sanitization on user-supplied data before rendering
-
Inspect email template handlingReview email confirmation message templates and the code that populates them with user input. Check if user-provided data is inserted into email subjects or bodies without sanitization.Affected if Email templates accept user input directly without encoding, allowing injected HTML/script to appear in confirmation messages
-
Verify HTML rendering in web pagesSubmit test input containing HTML characters (such as <b>test</b> or <script>alert(1)</script>) through identified input fields and observe if these characters are rendered as HTML or properly escaped when displayed back in the application.Affected if User input is rendered as raw HTML in web pages rather than being escaped to harmless text
Your environment is affected if CIGESv2 version 2.0 is running and user input fields lack proper sanitization, allowing HTML/script code to be rendered unescaped in web pages or email messages.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement proper input validation and output encoding/sanitization for all user-supplied data before rendering in web pages or embedding in email messages.
