CVE-2013-0727 in Global Mapper
Summary
by MITRE
Multiple untrusted search path vulnerabilities in Global Mapper 14.1.0 allow local users to gain privileges via a Trojan horse (1) dwmapi.dll or (2) ibfs32.dll file in the current working directory, as demonstrated by a directory that contains a .gmc, .gmg, .gmp, .gms, .gmw, or .opt file.

The vulnerability identified as CVE-2013-0727 represents a critical privilege escalation issue affecting Global Mapper version 14.1.0 and potentially other versions within the same release line. This flaw resides in the application's handling of dynamic link library loading mechanisms, specifically when processing geospatial project files with extensions such as .gmc, .gmg, .gmp, .gms, .gmw, and .opt. The core issue manifests when the application attempts to load system libraries without proper validation of the library source or path, creating an exploitable condition that allows local attackers to execute arbitrary code with elevated privileges.
The technical implementation of this vulnerability stems from the application's insecure library loading practices, which aligns with common CWE classifications including CWE-426 Untrusted Search Path and CWE-74 Improper Neutralization of Special Elements in Output. When Global Mapper processes a geospatial project file, it traverses the current working directory to locate required dynamic libraries. Attackers can exploit this behavior by placing malicious versions of legitimate system libraries such as dwmapi.dll or ibfs32.dll in the same directory as the project file. The application, lacking proper path validation or library integrity checks, loads these malicious libraries instead of the legitimate system versions, effectively executing attacker-controlled code within the context of the application's privileges.
This vulnerability presents significant operational impact for organizations relying on Global Mapper for geospatial data processing and mapping operations. The privilege escalation aspect means that local attackers with minimal access to the system can potentially gain elevated privileges, potentially leading to complete system compromise. The attack vector is particularly concerning because it requires no specialized knowledge beyond placing files in specific directories, making it accessible to a wide range of threat actors. The vulnerability affects not just individual users but entire organizational networks where multiple users might interact with geospatial data files, creating potential for widespread compromise through a single vulnerable installation.
The exploitation of this vulnerability directly maps to several ATT&CK techniques including T1059 Command and Scripting Interpreter and T1548.1 Valid Accounts, as attackers can leverage the elevated privileges gained through this mechanism to execute further malicious activities. Organizations should implement immediate mitigations including updating to the latest version of Global Mapper where this vulnerability has been addressed, implementing strict file access controls, and monitoring for unauthorized library modifications in directories containing geospatial project files. Additionally, system administrators should consider implementing application whitelisting policies and ensuring that system libraries are properly secured against unauthorized modifications, as the vulnerability essentially allows attackers to bypass normal security controls through legitimate system interface mechanisms.
