CVE-2018-7886: An issue was discovered in CloudMe 1.11.0.

An issue was discovered in CloudMe 1.11.0. An unauthenticated local attacker that can connect to the "CloudMe Sync" client application listening on 127.0.0.1 port 8888 can send a malicious payload causing a buffer overflow condition. This will result in code execution, as demonstrated by a TCP reverse shell, or a crash. NOTE: this vulnerability exists because of an incomplete fix for CVE-2018-6892.

Security readout for executives and security teams

Plain-English summary

CloudMe Sync 1.11.0 has a local buffer overflow in its client service on 127.0.0.1:8888. A local unauthenticated user or process that can reach that port could crash the client or execute code. This is not described as remotely internet-exploitable, but public exploit references exist.

Executive priority

Treat this as a targeted endpoint remediation issue, not an internet-wide emergency. Prioritize shared or high-value workstations where CloudMe Sync 1.11.0 is present. Public exploit material increases urgency for stale deployments.

Technical view

The CloudMe Sync client in version 1.11.0 accepts local TCP connections on 127.0.0.1:8888. A malicious payload can trigger a buffer overflow leading to code execution or denial of service. The CVE notes this resulted from an incomplete fix for CVE-2018-6892. No CVSS, CWE, vendor patch, or KEV listing is provided.

Likely exposure

Exposure is limited to systems running CloudMe Sync 1.11.0 with the local listener active. Risk is higher on shared endpoints, compromised desktops, or systems where untrusted local users or processes can connect to localhost services.

Exploitation context

The source bundle cites Exploit-DB and a public write-up, and the CVE description says code execution was demonstrated. CISA KEV status is false, and the provided sources do not establish active exploitation in the wild.

Researcher notes

Evidence is version-specific and limited. The CVE names CloudMe 1.11.0, local localhost access, buffer overflow, code execution or crash, and an incomplete CVE-2018-6892 fix. No authoritative patch details or affected version range beyond 1.11.0 are provided.

Mitigation direction

  • Inventory endpoints for CloudMe Sync 1.11.0 installations.
  • Check CloudMe vendor guidance for a corrected version or supported remediation.
  • Remove CloudMe Sync where it is not business-required.
  • Restrict untrusted local user access on affected systems.
  • Monitor affected endpoints for unexpected CloudMe Sync crashes or behavior.

Validation and detection

  • Confirm whether CloudMe Sync 1.11.0 is installed.
  • Check whether the client listens on 127.0.0.1 port 8888.
  • Review endpoint software inventory for older CloudMe versions.
  • Correlate crash logs or alerts involving CloudMe Sync.
  • Document compensating controls where immediate removal is not possible.
