CVE-2012-0299
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 · uneditedThe file-management scripts in the management GUI in Symantec Web Gateway 5.0.x before 5.0.3 allow remote attackers to upload arbitrary code to a designated pathname, and possibly execute this code, via unspecified vectors.
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 confidenceThe file-management scripts in the management GUI of Symantec Web Gateway versions 5.0.x before 5.0.3 contain an arbitrary file upload vulnerability. This allows remote unauthenticated attackers to upload malicious code to specified paths on the system and potentially execute it, leading to complete system compromise.

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 Symantec Web Gateway is installedLocate and examine the installation directory or check system processes for Symantec Web Gateway componentsAffected if Symantec Web Gateway software is present on the system
-
Identify the installed versionAccess the management GUI help section or check the system version information to determine the exact version numberAffected if The version is 5.0, 5.0.1, or 5.0.2 exactly
-
Determine if the management GUI is network-accessibleTest connectivity to the management GUI web interface from external network locations or verify firewall rules allowing remote accessAffected if The management GUI is reachable from untrusted networks without restriction
-
Verify file upload functionality in the management interfaceAccess the file-management scripts within the management GUI and confirm that file upload to arbitrary paths is permitted without authenticationAffected if Unauthenticated file upload to specified paths is possible through the management interface
The environment is affected if Symantec Web Gateway versions 5.0, 5.0.1, or 5.0.2 are installed with the management GUI accessible to remote unauthenticated users.

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 to Symantec Web Gateway 5.0.3 or later to remediate this vulnerability. If immediate patching is not feasible, disable or restrict access to the management GUI to trusted/internal networks only.
Symantec Web Gateway 5.0.3
- Download Symantec Web Gateway version 5.0.3 or later from the official Symantec support portal
- Review upgrade documentation and release notes
- Backup the current configuration and any critical data
- Deploy the upgrade in a test environment first if possible
- Apply the upgrade to production systems
- Verify the upgrade was successful and the management GUI is functional
