CVE-2026-8362
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 · uneditedA stack-based buffer overflow condition exists in WOSDefaultHttpModule.dll when processing a long URL path starting with /woshome
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 confidenceA stack-based buffer overflow vulnerability exists in WOSDefaultHttpModule.dll where processing an excessively long URL path beginning with /woshome causes data to overflow stack-allocated buffers. This memory corruption can potentially allow remote attackers to execute arbitrary code by overwriting return addresses or adjacent stack variables.

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.
-
Locate WOSDefaultHttpModule.dll on the systemSearch for the file WOSDefaultHttpModule.dll in common installation directories (e.g., C:\Program Files\, C:\Program Files (x86)\, or web server root folders) using file explorer or command: dir /s /b C:\*WOSDefaultHttpModule.dll 2>nul or find / -name WOSDefaultHttpModule.dll on LinuxAffected if The DLL file exists in the environment - this indicates the vulnerable component is present
-
Identify the web service using this moduleCheck running processes and services that reference WOSDefaultHttpModule.dll, or examine IIS/apache/nginx configuration files for modules loading this DLLAffected if The DLL is loaded by a running web server process - this means the vulnerable code is active in memory
-
Verify /woshome endpoint accessibilitySend an HTTP request to the server with a path beginning with /woshome (e.g., GET /woshome HTTP/1.1) and observe the responseAffected if The endpoint responds (even with an error) - this confirms the vulnerable URL handling code path is accessible over the network
-
Confirm the module handles URL paths without length validationReview web server configuration or proxy rules for any RewriteRules or URL mappings that route /woshome* paths to WOSDefaultHttpModule.dll, and check if there are explicit path length limits configuredAffected if No explicit URL path length limits are configured or enforced before requests reach WOSDefaultHttpModule.dll - the vulnerable code path is unprotected
A user is affected if WOSDefaultHttpModule.dll is present AND the /woshome URL endpoint is accessible without enforced length limits on the incoming path

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 dataImplement strict input length validation on URL path processing within WOSDefaultHttpModule.dll, ensuring paths are truncated or rejected before copying into fixed-size stack buffers. Consider migrating to heap-allocated buffers or safe string functions that prevent overflows.
