CVE-2019-13637: In LogMeIn join.me before 3.16.0.5505, an attacker could execute arbitrary commands on a targeted system.

In LogMeIn join.me before 3.16.0.5505, an attacker could execute arbitrary commands on a targeted system. This vulnerability is due to unsafe search paths used by the application URI that is defined in Windows. An attacker could exploit this vulnerability by convincing a targeted user to follow a malicious link. Successful exploitation could cause the application to load libraries from the directory targeted by the URI link. The attacker could use this behavior to execute arbitrary commands on the system with the privileges of the targeted user if the attacker can place a crafted library in a directory that is accessible to the vulnerable system.

Security readout for executives and security teams

Plain-English summary

CVE-2019-13637 affects LogMeIn join.me before 3.16.0.5505 on Windows. A malicious link could make the app load code from an unsafe location, allowing commands to run as the targeted user if the attacker can place a crafted library where the system can reach it.

Executive priority

Treat this as a targeted endpoint risk, not an internet-wide emergency. Prioritize organizations with unmanaged Windows desktops, legacy remote-collaboration tools, or users likely to receive phishing links.

Technical view

The issue is unsafe Windows application URI search path handling in join.me. Exploitation requires user interaction through a malicious link and a reachable attacker-controlled library location. Successful exploitation can execute arbitrary commands with the privileges of the user running join.me.

Likely exposure

Likely exposure is Windows endpoints with join.me versions earlier than 3.16.0.5505. The source bundle does not provide CPEs, deployment prevalence, or vendor environment details.

Exploitation context

The source bundle does not show CISA KEV listing or cited evidence of active exploitation. Exploitation is not drive-by; it depends on convincing a user to open a malicious link and on library placement conditions.

Researcher notes

Evidence is limited to the CVE description and referenced advisory. No CVSS, CWE, CPE, or public exploitation signal is included in the bundle. Do not assume broader LogMeIn products are affected without vendor evidence.

Mitigation direction

  • Inventory Windows endpoints for LogMeIn join.me installations.
  • Upgrade join.me to 3.16.0.5505 or later where present.
  • Remove join.me from systems where it is no longer required.
  • Check vendor or current owner guidance for any additional hardening.
  • Use endpoint controls to reduce untrusted library loading opportunities.

Validation and detection

  • Confirm installed join.me versions are not earlier than 3.16.0.5505.
  • Review software inventory for legacy join.me deployments.
  • Check Windows URI handler registrations related to join.me.
  • Review endpoint alerts for suspicious child processes from join.me.
  • Validate remediation on a representative endpoint before broad rollout.
