CVE-2021-26750
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 · uneditedDLL hijacking in Panda Agent <=1.16.11 in Panda Security, S.L.U. Panda Adaptive Defense 360 <= 8.0.17 allows attacker to escalate privileges via maliciously crafted DLL file.
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 DLL hijacking vulnerability exists in Panda Agent <=1.16.11 and Panda Adaptive Defense 360 <=8.0.17 where the application loads DLLs from insecure paths, allowing an attacker to place a maliciously crafted DLL that gets loaded 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 Panda Agent versionOpen Windows Control Panel > Programs and Features, or use PowerShell: Get-ItemProperty 'HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\*' | Select-Object DisplayName, DisplayVersion | Where-Object {$_.DisplayName -like '*Panda*Agent*'}Affected if The displayed version is 1.16.11 or lower
-
Check Panda Adaptive Defense 360 versionOpen Windows Control Panel > Programs and Features, or use PowerShell: Get-ItemProperty 'HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\*' | Select-Object DisplayName, DisplayVersion | Where-Object {$_.DisplayName -like '*Panda*Adaptive*Defense*360*'}Affected if The displayed version is 8.0.17 or lower
-
Confirm product is running with elevated privilegesOpen Task Manager, look for Panda processes (such as PandaSVC.exe, PandaDLPSb.exe, or PavPrxSvc.exe), right-click and check 'Run as administrator' status, or verify the process runs under a privileged accountAffected if The Panda product runs with administrator or SYSTEM privileges while loading DLLs from insecure paths (this is the vulnerable condition for CVE-2021-26750)
If the installed version of Panda Agent is 1.16.11 or lower, or Panda Adaptive Defense 360 is 8.0.17 or lower, and the application runs with elevated privileges, the environment is affected by CVE-2021-26750.

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 dataUpdate to a patched version of Panda Agent (>=1.16.12) and Panda Adaptive Defense 360 (>=8.0.18), or ensure the application uses secure DLL search paths and only loads DLLs from trusted locations.
