CVE-2009-0693
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 · uneditedMultiple buffer overflows in Wyse Device Manager (WDM) 4.7.x allow remote attackers to execute arbitrary code via (1) the User-Agent HTTP header to hserver.dll or (2) unspecified input to hagent.exe.
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 confidenceBuffer overflow vulnerabilities in Wyse Device Manager 4.7.x allow remote attackers to execute arbitrary code by sending specially crafted User-Agent HTTP headers to hserver.dll or unspecified input to hagent.exe, achieving unauthenticated remote 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.
-
Confirm Wyse Device Manager installationSearch for WDM installation directories or check Windows services for 'Wyse Device Manager' or 'WDM' named servicesAffected if WDM is installed on the system
-
Identify installed WDM versionCheck the program's version information: look in Add/Remove Programs, or check version info on hserver.dll or hagent.exe files in the WDM installation folderAffected if Installed version is 4.7.0, 4.7.1, or 4.7.2 exactly
-
Verify hserver.dll HTTP service is exposedCheck if the WDM HTTP server service is running and accessible externally - look for port 80/443 listeners bound to network interfaces (not localhost only) in the WDM configurationAffected if hserver.dll HTTP service is running and bound to accessible network interfaces
-
Check hagent.exe service statusVerify if the hagent.exe service/agent component is installed and running - check Windows services or the WDM installation for this executableAffected if hagent.exe service is installed and running
A system is affected if Wyse Device Manager version 4.7.0, 4.7.1, or 4.7.2 is installed with either the hserver.dll HTTP service or hagent.exe service exposed to network access.

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 dataApply available patches from Wyse for WDM 4.7.x; if patches are unavailable due to product age, restrict network access to WDM services to trusted sources only, or consider upgrading to a supported version.
