Low risk44th percentile - higher than 44% of all known CVEs
Summary
A path traversal vulnerability exists in the campaign import feature of Mautic 7. When extracting uploaded ZIP files during campaign imports, a flaw in the validation logic allows file paths to escape the intended temporary directories. An authenticated user with campaign import privileges can write arbitrary PHP files to sensitive system directories, leading to Remote Code Execution (RCE) under the web server user context.
Risk Assessment
An attacker can overwrite critical configuration or cache files, gaining full control over the web server and potentially the entire Mautic infrastructure.
Recommendation
Immediately update Mautic to a version that fixes the path traversal vulnerability in campaign import. Until the update, restrict campaign import privileges to trusted users only.
Original NVD description (English source)
A path traversal vulnerability exists in the campaign import feature of Mautic 7. When extracting uploaded ZIP files during campaign imports, a flaw in the validation logic allows file paths to escape the intended temporary directories. An authenticated user with campaign import privileges (campaign:imports:create) can write arbitrary PHP files to sensitive system directories. An attacker can exploit this to overwrite critical internal configuration or cache components, resulting in Remote Code Execution (RCE) under the context of the web server user.
