Administrator code execution via tampered upload filename
Published Apr 15, 2024 · Updated Aug 9, 2024
Arbitrary file upload in EverestThemes Everest Backup before 2.2.5 allows remote authenticated users to place executable PHP on the server. The Restore uploader accepts backup content but trusts the multipart Content-Disposition filename, allowing its expected .ebwp extension to be replaced with .php. Administrator access is required; requesting the resulting web-accessible PHP file executes supplied commands.
