CVE-2018-10519: CMS Made Simple (CMSMS) 2.2.7 contains a privilege escalation vulnerability from ordinary user to admin use...

CMS Made Simple (CMSMS) 2.2.7 contains a privilege escalation vulnerability from ordinary user to admin user by arranging for the eff_uid value within $_COOKIE[$this->_loginkey] to equal 1, because files in the tmp/ directory are accessible through HTTP requests. NOTE: this vulnerability exists because of an incorrect fix for CVE-2018-10084.

Security readout for executives and security teams

Plain-English summary

CMS Made Simple 2.2.7 has a flaw that can let an ordinary authenticated user become an administrator. For a public CMS, that can mean control of content, users, and site configuration. The source bundle does not provide CVSS, KEV listing, or a vendor fix version.

Executive priority

Treat confirmed CMSMS 2.2.7 exposure as urgent, especially on internet-facing sites. The business risk is site administration takeover after lower-privileged access. Prioritize inventory, upgrade guidance, and access review before broader remediation planning.

Technical view

CVE-2018-10519 describes privilege escalation in CMSMS 2.2.7 caused by an incomplete fix for CVE-2018-10084. The issue involves trusted login state and HTTP-accessible tmp directory files. The bundle identifies CMS Made Simple 2.2.7 but provides limited affected-version and remediation detail.

Likely exposure

Exposure is likely limited to CMS Made Simple 2.2.7 deployments, especially where ordinary user accounts exist and the tmp directory is reachable over HTTP. The bundle does not identify other affected versions.

Exploitation context

The source bundle does not show CISA KEV status or confirmed active exploitation. A public GitHub reference is listed, so defenders should assume technical details may be available, but active exploitation is not established by the provided sources.

Researcher notes

Evidence is narrow but specific: CMSMS 2.2.7, ordinary-user-to-admin escalation, HTTP-accessible tmp files, and linkage to an incorrect CVE-2018-10084 fix. No CVSS, CWE, full affected-version range, or definitive patch version is present in the bundle.

Mitigation direction

  • Identify all CMS Made Simple deployments and confirm whether version 2.2.7 is present.
  • Check vendor guidance for the fixed version or supported mitigation.
  • Restrict HTTP access to CMSMS temporary directories where possible.
  • Review ordinary CMS user accounts and remove unnecessary access.
  • Prioritize upgrade or isolation for internet-facing CMSMS 2.2.7 systems.

Validation and detection

  • Inventory public and internal CMSMS sites and record exact application versions.
  • Verify whether the tmp directory is reachable through direct HTTP requests.
  • Review CMS audit logs for unexpected administrator role changes.
  • Check recent content, template, plugin, and user-management changes.
  • Confirm remediation against vendor release notes or advisory guidance.
