Critical · published March 20, 2020
CVSS calls it critical at 9.8. It is confirmed in active exploitation. It sits in the 100.0th percentile for exploit probability.
🚨 Deserialization of untrusted data in Liferay Portal can hand remote attackers the keys to your castle — all they need is a JSON web service call! 🔥 Think of it as a restaurant allowing customers to submit their own recipes without checking the ingredients first. If the kitchen blindly accepts these submissions, anyone could sneak in a dish that’s not just unappetizing, but downright dangerous! An attacker could exploit this vulnerability to execute arbitrary code on the server, leading to catastrophic outcomes like data breaches or complete server takeover. Imagine the chaos if someone could change the menu to serve up malicious content instead!
