What it is

⚠️ A sneaky directory traversal vulnerability lurks in ELECOM File Manager, giving attackers the keys to your files—allowing them to create or overwrite files with ease! Think of it like a delivery service that, without proper checks, allows anyone to slip in a package for any address, including those they shouldn't access. Here, attackers can send files right into restricted directories, exploiting the app's permissions! This means an attacker could potentially overwrite crucial files or inject malicious content, leading to data loss or compromise. Imagine waking up one day only to find crucial documents replaced or damaged—absolutely devastating!
