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 · unedited
SAP Business Client, version 7.0, allows an attacker after a successful social engineering attack to inject malicious code as a DLL file in untrusted directories that can be executed by the application, due to uncontrolled search path element. An attacker could thereby control the behavior of the application.

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 · high confidence

SAP Business Client version 7.0 contains an uncontrolled search path element vulnerability (DLL hijacking). The application searches for and loads DLL files from untrusted directories before checking trusted system directories. An attacker who uses social engineering to convince a user to place a malicious DLL in such an untrusted directory can achieve arbitrary code execution when the application loads the DLL.

MitigationApply SAP security patches for CVE-2020-6244. Ensure the application runs from trusted directories with proper access controls and configure the DLL search path to exclude user-writable directories.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify installed SAP Business Client version
    Open SAP Business Client and navigate to Help > About SAP Business Client, or check the program's file properties (right-click the executable > Properties > Details). Look for the version number in the format X.X.
    Affected if The version displayed is 6.0, 6.5, or 7.0 exactly.
  2. Locate the SAP Business Client executable directory
    Find the folder where sapboc.exe or the SAP Business Client executable is installed. Default locations may include C:\Program Files\SAP\ or C:\Program Files (x86)\SAP\.
    Affected if The application is installed or run from a directory that is user-writable or located in a less trusted path (e.g., Downloads, Desktop, or a network share).
  3. Verify DLL search path configuration
    Run the application while monitoring DLL loading using Process Monitor (procmon.exe from Sysinternals). Set a filter for the SAP Business Client process and observe which directories it searches for DLLs.
    Affected if The process attempts to load DLLs from directories outside the Windows system directories before checking trusted locations.
  4. Check for presence of writable directories in common search paths
    Examine the application's working directory and any directories listed in the PATH environment variable that the application uses. Verify if any of these directories are user-writable.
    Affected if Any directory in the DLL search order is writable by non-privileged users, allowing them to place a malicious DLL file.

A user is affected if they have SAP Business Client version 6.0, 6.5, or 7.0 installed AND the application runs from or loads DLLs from user-writable directories.
