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.

Weakness

The product searches for critical resources using an externally-supplied search path that can point to resources that are not under the product’s direct control.

Affected Software

Name Vendor Start Version End Version
Join.me Logmeininc * 3.16.0.5505 (excluding)

Extended Description

This might allow attackers to execute their own programs, access unauthorized data files, or modify configuration in unexpected ways. If the product uses a search path to locate critical resources such as programs, then an attacker could modify that search path to point to a malicious program, which the targeted product would then execute. The problem extends to any type of critical resource that the product trusts. Some of the most common variants of untrusted search path are:
