An issue was discovered in IDM UltraEdit through 24.10.0.32. To exploit the vulnerability, on unpatched Windows systems, an attacker could include in the same directory as the affected executable a DLL using the name of a Windows DLL. This DLL must be preloaded by the executable (for example, ntmarta.dll). When the installer EXE is executed by the user, the DLL located in the EXEs current directory will be loaded instead of the Windows DLL, allowing the attacker to run arbitrary code on the affected 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
Ultraedit Ultraedit * 24.10.0.32

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:
