Ninja Forms - File Upload <= 3.3.26 - Unauthenticated Arbitrary File Upload
Noroxi assessment
Priority: Plan (action score 58/100)
- A ready-made attack module is public (Nuclei); exploiting it takes no special expertise.
- Public proof-of-concept code exists (Exploit-DB, GitHub); there is no record of exploitation in the wild.
- Probability of exploitation in the next 30 days: 62.9% (FIRST EPSS); higher than 99.1% of all records.
- Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
- According to CISA the attack is automatable: targets can be found by mass scanning.
- Fixed version: SaturdayDrive Ninja Forms - File Uploads 3.3.25.
Add it to your regular patch cycle. Upgrade to SaturdayDrive Ninja Forms - File Uploads 3.3.25 or later.
Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it
Primary sources: NVD · CVE.org · FIRST EPSS
The Ninja Forms - File Uploads plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the 'NF_FU_AJAX_Controllers_Uploads::handle_upload' function in all versions up to, and including, 3.3.26. This makes it possible for unauthenticated attackers to upload arbitrary files on the affected site's server which may make remote code execution possible. Note: The vulnerability was partially patched in version 3.3.25 and fully patched in version 3.3.27.
