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
webTareas 2.0.p8 contains a file deletion vulnerability in the print_layout.php administration component that allows authenticated attackers to delete arbitrary files. Attackers can exploit the vulnerability by manipulating the 'atttmp1' parameter to specify and delete files on the server through an unauthenticated file deletion mechanism.

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

webTareas 2.0.p8 contains a file deletion vulnerability in the print_layout.php administration component. Authenticated attackers can manipulate the 'atttmp1' parameter to specify and delete arbitrary files on the server, likely due to insufficient input validation and authorization checks on the file path.

MitigationRestrict file deletion to authorized users only and implement strict input validation on the 'atttmp1' parameter to prevent directory traversal and ensure only intended files can be deleted. Consider removing direct file operations from the web application entirely or using whitelisted file paths.

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 webTareas installation and version
    Locate webTareas on the server and determine the installed version by examining version files, headers, or application metadata
    Affected if The installed version matches or precedes 2.0.p8 (the affected version range)
  2. Locate print_layout.php file
    Search the webTareas installation directory for the print_layout.php file, typically found in admin or administration paths
    Affected if The print_layout.php file exists in the webTareas installation
  3. Verify atttmp1 parameter handling
    Examine the print_layout.php source code to see how the 'atttmp1' parameter is processed and whether file path inputs are validated before deletion operations
    Affected if The 'atttmp1' parameter accepts file paths without proper sanitization or path traversal protection
  4. Check authentication requirements for print_layout.php
    Review how print_layout.php handles authentication and authorization - test whether unauthenticated or low-privilege users can access the file deletion functionality
    Affected if The component lacks proper authentication checks or allows authenticated users to delete files outside expected directories

A user is affected if webTareas 2.0.p8 (or earlier versions) is installed, the print_layout.php file exists, and the 'atttmp1' parameter can be manipulated to delete arbitrary files without proper validation or authorization controls.

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

Restrict file deletion to authorized users only and implement strict input validation on the 'atttmp1' parameter to prevent directory traversal and ensure only intended files can be deleted. Consider removing direct file operations from the web application entirely or using whitelisted file paths.
