CVE-2007-1196
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 · uneditedUnspecified vulnerability in Citrix Presentation Server Client for Windows before 10.0 allows remote web sites to execute arbitrary code via unspecified vectors, related to the implementation of ICA connectivity through proxy servers.
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 · moderate confidenceThis is a remote code execution vulnerability in the Citrix Presentation Server Client for Windows (versions prior to 10.0). The flaw exists in how the client handles ICA connectivity through proxy servers, allowing malicious web sites to potentially execute arbitrary code on affected Windows clients.

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.
-
Verify Citrix Presentation Server Client installationOpen Windows Control Panel and look for 'Citrix Presentation Server Client' or 'Citrix ICA Client' in the list of installed programs, or check the program directory (typically C:\Program Files\Citrix) for Citrix client executablesAffected if Citrix Presentation Server Client is not installed on the system
-
Determine the installed client versionRight-click the Citrix client executable (commonly wfcrun32.exe or pn.exe) in the Program Files\Citrix folder, select Properties, and view the Version tab. Alternatively, open a command prompt and run 'wfcrun32.exe -version' if availableAffected if The displayed version number is 9.200 or lower (including 9.x versions prior to 9.200)
-
Check for ICA proxy connectivity configurationOpen the Citrix Connection Manager or ICA Client settings (typically accessible from the Windows Start menu under Citrix programs), then locate the proxy or network settings configuration panel. Look for any proxy server settings that enable ICA traffic to route through proxy serversAffected if Proxy settings are configured and enabled for ICA connections - this is the specific configuration path through which the vulnerability can be exploited
A system is affected if it has Citrix Presentation Server Client version 9.200 or earlier installed with proxy settings enabled for ICA connectivity, allowing malicious web sites to potentially execute arbitrary code through the client.

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.
dbcve · scopedUpgrade Citrix Presentation Server Client for Windows to version 10.0 or later. Until patched, restrict user access to untrusted websites and ensure proper network segmentation around Citrix infrastructure.
Citrix Presentation Server Client 10.0 or later
- 1. Identify all systems running Citrix Presentation Server Client for Windows version 9.200 or earlier
- 2. Download Citrix Presentation Server Client version 10.0 or later from the official Citrix website
- 3. Test the upgrade in a non-production environment first
- 4. Deploy the upgrade to production systems following standard change management procedures
- 5. Verify the client version post-upgrade by checking the client properties or ICA file handling
