CVE-2024-57964
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedInsecure Loading of Dynamic Link Libraries have been discovered in HVAC Energy Saving Program, which could allow local attackers to potentially disclose information or execute arbitray code on affected systems. This issue affects HVAC Energy Saving Program:.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceThis is a DLL hijacking vulnerability in HVAC Energy Saving Program where the application insecurely loads dynamic link libraries, potentially from untrusted paths. A local attacker could place a malicious DLL in a location the application searches, achieving information disclosure or arbitrary code execution with the privileges of the affected application.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify if HVAC Energy Saving Program is installedSearch for the application in Program Files directories, check installed programs list via Windows Registry at HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall, or look for executable files with names like 'HVAC', 'Energy Saving', or similar patterns in the systemAffected if The application is present on the system
-
Locate the application executableFind the main .exe file for HVAC Energy Saving Program using file search or by right-clicking the application shortcut and selecting 'Open file location'Affected if The executable exists and is accessible
-
Analyze DLL dependencies and loading behaviorUse tools like 'dumpbin /dependents' on the main executable to list required DLLs, or use Process Monitor during application startup to capture DLL load attempts. Check for DLLs that the application attempts to load from the current directory or untrusted pathsAffected if The application loads DLLs from directories writable by standard users (current directory, temp folders, or network paths)
-
Examine application DLL search pathsReview the application's manifest for loaded assemblies using 'mt.exe -inputmanifest:app.exe' or inspect the executable with a PE analysis tool. Use Process Monitor to filter by 'Path Contains' and observe DLL search order during runtimeAffected if DLL search paths include locations like '.', '%CD%', or untrusted network paths rather than only secure absolute paths
-
Verify DLL hijacking opportunityCheck if any DLL the application attempts to load does not exist in the application directory but would be found in a user-writable location in the search order. List all DLLs the application attempts to load and check each location in the search path hierarchyAffected if A missing DLL in the application directory can be placed by an attacker in an earlier search path location
The system is affected if HVAC Energy Saving Program is installed and the application loads DLLs from untrusted or user-writable paths, allowing an attacker to place a malicious DLL that gets loaded by the application.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataThe vendor should fix this vulnerability by implementing secure DLL loading practices: use absolute paths for all DLL references, remove unsafe search path dependencies, and validate DLL signatures before loading. Users should apply vendor patches when available and avoid running the application from untrusted network locations.
