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.
Conclusion & alert: CVE-2018-6892 is rated High Exploit Risk (88.5/100): CVSS Critical severity, with high exploitation likelihood (EPSS 89.67%, 100th percentile). Core evidence: 10 public exploit reference(s) are indexed (Exploit-DB). Mandatory action: Public exploits are available—assess exposure, apply mitigations, and prioritize patching.
Risk is dynamic; we continuously reassess and refresh what is shown on this page as upstream context changes.
