CVE-2024-45186
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 · uneditedFileSender before 2.49 allows server-side template injection (SSTI) for retrieving credentials.
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 confidenceFileSender before version 2.49 contains a server-side template injection (SSTI) vulnerability that allows remote attackers to inject malicious template code into the server-side template engine, enabling retrieval of sensitive credentials stored on the system.

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.
-
Determine installed FileSender versionAccess the FileSender admin interface and navigate to the 'About' or 'System Information' page to view the exact version number. Alternatively, check the version.php file in the FileSender installation directory if you have filesystem access.Affected if The displayed version is earlier than 2.49 (for example, 2.48, 2.47, etc.)
-
Identify if template rendering is enabledCheck the FileSender configuration file (typically config.php or equivalent in the installation directory) for template-related settings. Look for template engine configuration options that indicate server-side template processing is active.Affected if Template rendering or the template engine is enabled in the configuration, making the SSTI attack surface active.
-
Review template files for unauthorized modificationsExamine the template files in the FileSender templates directory (commonly found in a 'templates' or 'views' subdirectory within the installation). Compare file hashes or modification timestamps against known-good baselines if available.Affected if Unexpected or recently modified template files are present that were not authored by your organization.
-
Inspect application logs for template injection attemptsReview FileSender application logs (typically stored in a 'logs' directory or configured log location) for patterns indicating SSTI probes, such as '{{', '{%', or other template syntax in request parameters that may have been logged.Affected if Logs contain requests with template syntax characters ({{, {%, {#) in input fields, suggesting exploitation attempts.
You are affected if your installed FileSender version is before 2.49 AND template rendering is enabled in your configuration, as this combination allows the SSTI vulnerability to be exploited.

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 dataUpgrade FileSender to version 2.49 or later to patch the SSTI vulnerability. Apply the update as soon as possible given the critical (9.8) CVSS score.
