EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.

Description

An issue was discovered in CloudMe before 1.11.0. An unauthenticated remote attacker that can connect to the "CloudMe Sync" client application listening on port 8888 can send a malicious payload causing a buffer overflow condition. This will result in an attacker controlling the program's execution flow and allowing arbitrary code execution.
