CVE-2005-1543
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 · uneditedMultiple stack-based and heap-based buffer overflows in Remote Management authentication (zenrem32.exe) on Novell ZENworks 6.5 Desktop and Server Management, ZENworks for Desktops 4.x, ZENworks for Servers 3.x, and Remote Management allows remote attackers to execute arbitrary code via (1) unspecified vectors, (2) type 1 authentication requests, and (3) type 2 authentication requests.
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 confidenceMultiple stack-based and heap-based buffer overflows in the Remote Management component (zenrem32.exe) of Novell ZENworks allow remote attackers to execute arbitrary code via malformed authentication requests (types 1, 2, and unspecified vectors). The vulnerability is exploitable over the network without authentication.

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 zenrem32.exe is presentSearch for the file zenrem32.exe on the system. Common locations include the ZENworks installation directory (e.g., C:\Novell\ZENworks\ or C:\Program Files\Novell\ZENworks\). Use file search or check installation directories.Affected if The file exists on the system, indicating the Remote Management component is installed.
-
Determine installed ZENworks versionCheck the installed version of Novell ZENworks. This can be done via Add/Remove Programs in Windows, or by checking version information in the ZENworks installation directory. Compare the version to the affected ranges: ZENworks 6.5, ZENworks Desktops 3.2/4.0/4.0.1, or ZENworks Servers 3.2.Affected if The installed version is 6.5, 4.0.1, 4.0, 3.2, or any version of Zenworks Remote Management.
-
Confirm Remote Management service is runningCheck if the Remote Management service is enabled and running. On Windows, open Services (services.msc) and look for services related to ZENworks Remote Management or ZENworks Remote Control. Also check for zenrem32.exe as a running process in Task Manager.Affected if The Remote Management service is running or the zenrem32.exe process is active.
-
Identify listening ports for Remote ManagementCheck for open ports associated with ZENworks Remote Management. Use netstat -an or a port scanner to look for ports typically used by Remote Management (commonly TCP 1761, 2710, or similar). This can be done locally with netstat or remotely with a network scanner.Affected if Ports used by ZENworks Remote Management are open and listening on network interfaces.
The system is affected if ZENworks with the Remote Management component (zenrem32.exe) is installed and the Remote Management service is running, regardless of version since all versions of Zenworks Remote Management are vulnerable.

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 dataApply vendor patches for affected ZENworks versions or upgrade to supported versions; if patches unavailable, restrict network access to Remote Management ports via firewall or disable the service until remediation is possible.
