| The Extended Control List (ECL) feature of the Java Virtual Machine (JVM) in Lotus Notes Client R5 allows malicious web site operators to determine the existence of files on the client by measuring delays in the execution of the getSystemResource method. | ||||
| CVE-2004-0243 | 1 Ibm | 1 Aix | 2026-04-16 | N/A |
| AIX 4.3.3 through AIX 5.1, when direct remote login is disabled, displays a different message if the password is correct, which allows remote attackers to guess the password via brute force methods. | ||||
| CVE-2004-0778 | 2 Gnu, Redhat | 2 Cvs, Enterprise Linux | 2026-04-16 | N/A |
| CVS 1.11.x before 1.11.17, and 1.12.x before 1.12.9, allows remote attackers to determine the existence of arbitrary files and directories via the -X command for an alternate history file, which causes different error messages to be returned. | ||||
| CVE-2004-1428 | 1 Argosoft | 1 Ftp Server | 2026-04-16 | N/A |
| ArGoSoft FTP before 1.4.2.1 generates an error message if the user name does not exist instead of prompting for a password, which allows remote attackers to determine valid usernames. | ||||
| CVE-2001-1528 | 1 Amtote | 1 Homebet | 2026-04-16 | N/A |
| AmTote International homebet program returns different error messages when invalid account numbers and PIN codes are provided, which allows remote attackers to determine the existence of valid account numbers via a brute force attack. | ||||
| CVE-2001-1387 | 2 Netfilter, Redhat | 2 Iptables, Linux | 2026-04-16 | N/A |
| iptables-save in iptables before 1.2.4 records the "--reject-with icmp-host-prohibited" rule as "--reject-with tcp-reset," which causes iptables to generate different responses than specified by the administrator, possibly leading to an information leak. | ||||
| CVE-2003-0190 | 4 Openbsd, Openpkg, Redhat and 1 more | 8 Openssh, Openpkg, Enterprise Linux and 5 more | 2026-04-16 | N/A |
| OpenSSH-portable (OpenSSH) 3.6.1p1 and earlier with PAM support enabled immediately sends an error message when a user does not exist, which allows remote attackers to determine valid usernames via a timing attack. | ||||
| CVE-2002-0514 | 1 Openbsd | 1 Openbsd | 2026-04-16 | N/A |
| PF in OpenBSD 3.0 with the return-rst rule sets the TTL to 128 in the RST packet, which allows remote attackers to determine if a port is being filtered because the TTL is different than the default TTL. | ||||
| CVE-2002-0515 | 1 Phildev | 1 Ipfilter | 2026-04-16 | N/A |
| IPFilter 3.4.25 and earlier sets a different TTL when a port is being filtered than when it is not being filtered, which allows remote attackers to identify filtered ports by comparing TTLs. | ||||
| CVE-2001-1483 | 1 Nrl.navy | 1 One-time Passwords In Everything | 2026-04-16 | N/A |
| One-Time Passwords In Everything (a.k.a OPIE) 2.32 and 2.4 allows remote attackers to determine the existence of user accounts by printing random passphrases if the user account does not exist and static passphrases if the user account does exist. | ||||
| CVE-2004-1602 | 1 Proftpd | 1 Proftpd | 2026-04-16 | N/A |
| ProFTPD 1.2.x, including 1.2.8 and 1.2.10, responds in a different amount of time when a given username exists, which allows remote attackers to identify valid usernames by timing the server response. | ||||
| CVE-2005-0918 | 2 Adobe, Microsoft | 2 Svg Viewer, Internet Explorer | 2026-04-16 | N/A |
| The NPSVG3.dll ActiveX control for Adobe SVG Viewer 3.02 and earlier, when running on Internet Explorer, allows remote attackers to determine the existence of arbitrary files by setting the src property to the target filename and using Javascript to determine if the web page immediately stops loading, which indicates whether the file exists or not. | ||||
| CVE-2004-2150 | 1 Nettica | 1 Intellipeer Email Server | 2026-04-16 | N/A |
| Nettica Corporation INTELLIPEER Email Server 1.01 displays different error messages for valid and invalid account names, which allows remote attackers to determine valid account names. | ||||

| The web mail service in Woppoware PostMaster 4.2.2 (build 3.2.5) generates different error messages depending on whether a user exists or not, which allows remote attackers to determine valid usernames. | ||||
| CVE-2025-41252 | 1 Vmware | 3 Cloud Foundation, Nsx, Nsx-t | 2026-04-15 | 7.5 High |
| Description: VMware NSX contains a username enumeration vulnerability. An unauthenticated malicious actor may exploit this to enumerate valid usernames, potentially leading to unauthorized access attempts. Impact: Username enumeration → facilitates unauthorized access. Attack Vector: Remote, unauthenticated. Severity: Important. CVSSv3: 7.5 (High). Acknowledgments: Reported by the National Security Agency. Affected Products: * VMware NSX 9.x.x.x, 4.2.x, 4.1.x, 4.0.x * NSX-T 3.x * VMware Cloud Foundation (with NSX) 5.x, 4.5.x Fixed Versions: * NSX 9.0.1.0; 4.2.2.2/4.2.3.1 http://4.2.2.2/4.2.3.1 ; 4.1.2.7; NSX-T 3.2.4.3; CCF async patch (KB88287). Workarounds: None. | ||||
| CVE-2023-37482 | 2026-04-15 | 5.3 Medium | ||
| The login functionality of the web server in affected devices does not normalize the response times of login attempts. An unauthenticated remote attacker could exploit this side-channel information to distinguish between valid and invalid usernames. | ||||
| CVE-2023-30312 | 2026-04-15 | 7.3 High | ||
| An issue discovered in OpenWrt 18.06, 19.07, 21.02, 22.03, and beyond allows off-path attackers to hijack TCP sessions, which could lead to a denial of service, impersonating the client to the server (e.g., for access to files over FTP), and impersonating the server to the client (e.g., to deliver false information from a finance website). This occurs because nf_conntrack_tcp_no_window_check is true by default. | ||||
| CVE-2023-36325 | 2026-04-15 | 3.7 Low | ||
| i2p before 2.3.0 (Java) allows de-anonymizing the public IPv4 and IPv6 addresses of i2p hidden services (aka eepsites) via a correlation attack across the IPv4 and IPv6 addresses that occurs when a tunneled, replayed message has a behavior discrepancy (it may be dropped, or may result in a Wrong Destination response). An attack would take days to complete. | ||||
| CVE-2024-11084 | 1 Perforce | 1 Helix Alm | 2026-04-15 | N/A |
| Helix ALM prior to 2025.1 returns distinct error responses during authentication, allowing an attacker to determine whether a username exists. | ||||
