CVE-2022-49038
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 · uneditedInclusion of functionality from untrusted control sphere vulnerability in OpenSSL DLL component in Synology Drive Client before 3.3.0-15082 allows local users to execute arbitrary code via unspecified vectors.
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 Synology Drive Client's bundled OpenSSL DLL component. The application loads OpenSSL DLLs from an untrusted location, allowing a local attacker to plant a malicious DLL that gets loaded and executed with the application's privileges, achieving arbitrary code execution.

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.
-
Verify Synology Drive Client is installedCheck for the presence of Synology Drive Client installation directory, typically found in C:\Program Files\Synology\Synology Drive or C:\Program Files (x86)\Synology\Synology Drive. Also check Windows Registry under HKEY_LOCAL_MACHINE\SOFTWARE\Synology\SynologyDrive or HKEY_CURRENT_USER\SOFTWARE\Synology\SynologyDrive.Affected if Synology Drive Client is found on the system.
-
Identify installed versionLocate the main executable (typically SynologyDrive.exe or SynologyDriveClient.exe) in the installation directory. Right-click the executable, select Properties, and view the Details tab to find the File Version. Alternatively, query the registry key HKEY_LOCAL_MACHINE\SOFTWARE\Synology\SynologyDrive\Version or similar path for version information.Affected if The installed version is below 3.3.0-15082.
-
Check for vulnerable OpenSSL DLL loadingMonitor the application process using Process Monitor (procmon) from Sysinternals. Set a filter for Process Name contains SynologyDrive and Operation contains Load Image. Look for OpenSSL DLLs (libssl.dll, libcrypto.dll, ssleay32.dll, libeay32.dll) being loaded from paths outside the application directory, particularly from locations writable by standard users (e.g., the application working directory, temp folders, or user-writable directories).Affected if OpenSSL DLLs are being loaded from paths outside the protected application directory.
-
Verify DLL search order vulnerabilityExamine the application manifest or use Process Monitor to determine if the application is vulnerable to DLL search order hijacking. Check if the application directory contains OpenSSL DLLs that could be replaced, or if it lacks a manifest requesting safe DLL search mode. Also verify if the working directory from which the application is launched is writable by other users.Affected if The application can be launched from a directory where untrusted users can place malicious DLLs that get loaded.
A user is affected if Synology Drive Client version is below 3.3.0-15082 AND the application loads OpenSSL DLLs from untrusted locations or from a directory where unprivileged users can write files.
