CVE-2017-5233
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 · uneditedRapid7 AppSpider Pro installers prior to version 6.14.053 contain a DLL preloading vulnerability, wherein it is possible for the installer to load a malicious DLL located in the current working directory of the installer.
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 confidenceThe AppSpider Pro installer prior to version 6.14.053 is vulnerable to DLL preloading/hijacking. The installer searches for required DLLs in the current working directory before checking system directories, allowing an attacker with local access to place a malicious DLL that will be loaded during installation, potentially executing arbitrary code with elevated privileges.

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.
-
Check installed AppSpider Pro versionOpen AppSpider Pro and navigate to Help > About, or check the program version in Add/Remove Programs (Windows) or the application binary metadataAffected if The version displayed is less than 6.14.053, indicating the installer used was vulnerable
-
Locate AppSpider Pro installer filesSearch for installer files (e.g., AppSpiderProSetup.exe, AppSpider*Setup*.exe) in download folders, installation media, or software distribution directoriesAffected if Any installer version found is earlier than 6.14.053 (check file properties or run the installer with /version flag if supported)
-
Inspect current working directories where installer was runCheck directories where AppSpider Pro was historically installed or unpacked for any unexpected DLL files (e.g., ssleay32.dll, libssl.dll, or other non-standard DLLs)Affected if Unknown or suspicious DLL files exist in directories where the installer was previously executed
-
Review user profiles for installer remnantsCheck temporary directories (e.g., %TEMP%, %USERPROFILE%\Downloads) for any AppSpider installer files that may have been runAffected if Old installer packages with version < 6.14.053 are found on the system
The system is affected if AppSpider Pro version or any installer present is earlier than 6.14.053, or if suspicious DLLs are found in directories where the installer was executed.

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 data6.14.053
Upgrade AppSpider Pro installer to version 6.14.053 or later which implements secure DLL loading practices (e.g., using full path for DLL loading or disabling safe DLL search mode). Verify no malicious DLLs exist in directories where the installer is run.
