Description:	Summary: Microsoft Windows is prone to a remote code execution (RCE) vulnerability. This VT has been deprecated and replaced by the VT 'Microsoft Help and Support Center Remote Code Execution Vulnerability (2229593)' (OID: 1.3.6.1.4.1.25623.1.0.902080) Vulnerability Insight: The flaws are due to: - An error in the 'MPC::HTML::UrlUnescapeW()' function within the Help and Support Center application (helpctr.exe) that does not properly check the return code of 'MPC::HexToNum()' when escaping URLs, which could allow attackers to bypass whitelist restrictions and invoke arbitrary help files. - An input validation error in the 'GetServerName()' function in the 'C:\WINDOWS\PCHealth\HelpCtr\System\sysinfo\commonFunc.js' script invoked via 'ShowServerName()' in 'C:\WINDOWS\PCHealth\HelpCtr\System\sysinfo\sysinfomain.htm', which could be exploited by attackers to execute arbitrary scripting code. Vulnerability Impact: Successful exploitation will allow remote attackers to execute arbitrary code or compromise a vulnerable system. Affected Software/OS: - Microsoft Windows XP Service Pack 2/3 - Microsoft Windows Server 2003 Service Pack 2 Solution: The vendor has released a patch for the issue.
