What it is

⚡ A sneaky vulnerability in QiHang Media's Digital Signage could expose your user credentials via cleartext cookies! Don't let attackers eavesdrop on your session! 🔥 This vulnerability is like sending a postcard with your personal information on it instead of a sealed envelope — anyone can read it while it’s in transit! Just like how a postcard can be intercepted, cookies sent over unencrypted connections can be easily captured by an attacker. If exploited, attackers could intercept user authentication credentials, leading to unauthorized access to sensitive systems. Imagine an intruder lurking in the shadows, capturing everything that’s meant to be private. Your authentication is at risk, and they could misuse this information to wreak havoc!
