Authenticated arbitrary file deletion via backslash traversal
Published May 1, 2025 · Updated May 2, 2025
Path traversal in java_server at commit 11a5bac8f4ba1c17e4bc1b27cad6d24868500e3a allows remote authenticated users to delete Windows files. FoodController splits the attacker-controlled img parameter only on forward slashes, appends the result to realPath, and passes it to File.delete(). A valid seller session and a real uploaded image reach the endpoint; Windows backslashes preserve traversal segments and permit deletion of files writable by the application process.
