CVE-2000-0420
HighExploitation Probability (EPSS)
Elevated risk71th percentile - higher than 71% of all known CVEs
Summary
The default configuration of SYSKEY in Windows 2000 stores the startup key in the registry, which could allow an attacker to recover it and use it to decrypt EFS data.
Risk Assessment
Attackers may gain access to the startup key, potentially leading to the decryption of sensitive data stored in EFS, compromising information security within the organization.
Recommendation
It is recommended to change the default SYSKEY configuration so that the startup key is not stored in the registry, and to implement additional security measures for EFS data.
Other vulnerabilities in Windows 2000
See all- CVE-2017-0166High
A privilege escalation vulnerability exists in Windows due to improper calculation of LDAP request buffer lengths. An attacker could exploit this vulnerability by sending malicious traffic to a Domain Controller using a specially crafted application.
- CVE-2023-45284Medium
The IsLocal function on Windows incorrectly detects reserved device names in some cases. Reserved names followed by spaces (e.g., "COM1 ") and names "COM" and "LPT" with superscript 1, 2, or 3 are incorrectly reported as local. The fix ensures IsLocal now correctly identifies these.
- CVE-2024-38217MediumActively exploited
Security feature bypass vulnerability in Windows Mark of the Web. It allows an attacker to bypass security protections related to files downloaded from the internet.
- CVE-2022-41091MediumActively exploited
Security feature bypass vulnerability in Windows Mark of the Web. It allows an attacker to bypass security protections related to files downloaded from the internet.
- CVE-2022-41049MediumActively exploited
Security feature bypass vulnerability in Windows Mark of the Web. It allows an attacker to bypass security protections related to files downloaded from the internet.
- CVE-2021-36934HighActively exploited
An elevation of privilege vulnerability exists due to overly permissive Access Control Lists (ACLs) on multiple system files, including the Security Accounts Manager (SAM) database. An attacker could run arbitrary code with SYSTEM privileges, install programs, view/change/delete data, or create new accounts with full user rights.
- CVE-2020-1067High
A remote code execution vulnerability in Windows due to improper handling of objects in memory. An attacker with a domain user account could exploit it by creating a specially crafted request. The update corrects how Windows handles objects in memory.
- CVE-2000-0222High
The installation for Windows 2000 does not activate the Administrator password until the system has rebooted, allowing remote attackers to connect to the ADMIN$ share without a password until the reboot occurs.
- CVE-1999-1105Medium
Windows 95, when Remote Administration and File Sharing for NetWare Networks is enabled, creates a share (C$) when an administrator logs in remotely, which allows remote attackers to read arbitrary files by mapping the network drive.
- CVE-1999-0444Medium
Remote attackers can perform a denial of service on Windows machines using malicious ARP packets, causing a message box to display for each packet or filling up log files.
Original NVD description (English source)
The default configuration of SYSKEY in Windows 2000 stores the startup key in the registry, which could allow an attacker tor ecover it and use it to decrypt Encrypted File System (EFS) data.
