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
Stack-based buffer overflow in SonicWALL SSL-VPN End-Point Interrogator/Installer ActiveX control (Aventail.EPInstaller) before 10.5.2 and 10.0.5 hotfix 3 allows remote attackers to execute arbitrary code via long (1) CabURL and (2) Location arguments to the Install3rdPartyComponent method.

dbcve analysis · high confidence

Stack-based buffer overflow in SonicWALL SSL-VPN End-Point Interrogator/Installer ActiveX control (Aventail.EPInstaller) allows remote attackers to execute arbitrary code via overly long CabURL and Location arguments to the Install3rdPartyComponent method, enabling complete system compromise.

MitigationUpgrade SonicWALL SSL-VPN to version 10.5.2 or later, or 10.0.5 hotfix 3 or later; alternatively, disable the Aventail.EPInstaller ActiveX control or implement network-level restrictions until patching is feasible.

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. Locate the Aventail.EPInstaller ActiveX control on the system
    Open Windows Registry Editor and navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Classes\CLSID\{ CLSID } or search for 'Aventail.EPInstaller' under HKEY_LOCAL_MACHINE\SOFTWARE\Classes. The control's CLSID can also be found by searching for 'EPInstaller' in the registry.
    Affected if The ActiveX control is registered on the system (registry keys exist under CLSID for this control).
  2. Determine the installed version of the ActiveX control
    Once the CLSID key is found, check the 'Version' or 'VersionNumber' string value in the registry, or locate the associated DLL file and view its file properties to obtain the version.
    Affected if The version is 10.5.1 or earlier, or exactly version 10.0.5.
  3. Verify if the ActiveX control is enabled in Internet Explorer
    Open Internet Explorer, go to Tools > Internet Options > Security > Custom Level, and check the settings for ActiveX controls. Alternatively, check the Windows registry under 'Software\Microsoft\Windows\CurrentVersion\Ext\Settings' for the control's CLSID to see if it is allowed.
    Affected if The ActiveX control is set to Enabled or Prompt (not Disabled).
  4. Confirm the Install3rdPartyComponent method is accessible
    Check the registry key HKEY_LOCAL_MACHINE\SOFTWARE\Classes\CLSID\{CLSID}\Methods or verify that the control's TypeLib is properly registered, indicating the method interface is exposed.
    Affected if The Install3rdPartyComponent method is listed and the control's interfaces are properly exposed (not blocked by security policies).

The system is affected if the Aventail.EPInstaller ActiveX control is present, enabled, and its version falls within 10.5.1 or earlier, or exactly 10.0.5.

Upgrade available Upgrade to a release after 10.5.1
Interim mitigation

Upgrade SonicWALL SSL-VPN to version 10.5.2 or later, or 10.0.5 hotfix 3 or later; alternatively, disable the Aventail.EPInstaller ActiveX control or implement network-level restrictions until patching is feasible.

Recommended fix High confidence

SonicWALL SSL-VPN 10.5.2 or later, or 10.0.5 with hotfix 3

  1. Identify the current version of SonicWALL SSL-VPN End-Point Interrogator/Installer ActiveX control (Aventail.EPInstaller) in the environment
  2. If the installed version is 10.5.1 or earlier, upgrade to SonicWALL SSL-VPN version 10.5.2 or later
  3. If the installed version is 10.0.5, apply hotfix 3 for version 10.0.5, or upgrade to a supported version
  4. Verify the upgrade was successful by checking the ActiveX control version shows 10.5.2 or later, or 10.0.5 with hotfix 3 applied
  5. Test that the SSL-VPN client functionality works normally after the upgrade
Caveat Standard upgrade best practices apply - test in non-production environment before deploying organization-wide
