What it is

🚨 An arbitrary file upload flaw lurks in Feehi CMS v2.0.8 and earlier! One crafty PHP file is all it takes for attackers to slip in and wreak havoc. 🔥 Think of this as a restaurant where the chef is too trusting; they allow any customer to submit recipes without checking their ingredients. An attacker could easily serve a dish that poisons the entire kitchen! If exploited, this vulnerability allows an attacker to upload malicious PHP files and execute arbitrary code, potentially leading to a complete compromise of the website. This could mean unauthorized access to sensitive data, manipulation of content, or even total control of the server. Yikes!

Think of this as a restaurant where the chef is too trusting; they allow any customer to submit recipes without checking their ingredients. An attacker could easily serve a dish that poisons the entire kitchen!

What to do

If exploited, this vulnerability allows an attacker to upload malicious PHP files and execute arbitrary code, potentially leading to a complete compromise of the website.
