CVE-2001-1483 1 Nrl.navy 1 One-time Passwords In Everything 2025-04-03 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-2004-1428 1 Argosoft 1 Ftp Server 2025-04-03 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-2004-0294 1 Yabbforumsoftware 1 Yet Another Bulletin Board 2025-04-03 N/A
YaBB 1 SP 1.3.1 displays different error messages when a user exists or not, which makes it easier for remote attackers to identify valid users and conduct a brute force password guessing attack.
CVE-2000-1117 1 Ibm 1 Lotus Notes 2025-04-03 N/A
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-2003-0190 4 Openbsd, Openpkg, Redhat and 1 more 8 Openssh, Openpkg, Enterprise Linux and 5 more 2025-04-03 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-2004-0243 1 Ibm 1 Aix 2025-04-03 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 2025-04-03 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-2003-0637 1 Novell 1 Ichain 2025-04-03 N/A
Novell iChain 2.2 before Support Pack 1 uses a shorter timeout for a non-existent user than a valid user, which makes it easier for remote attackers to guess usernames and conduct brute force password guessing.
CVE-2005-1650 1 Woppoware 1 Postmaster 2025-04-03 N/A
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-2002-0208 1 Network.associates 1 Pgpfire 2025-04-03 N/A
PGP Security PGPfire 7.1 for Windows alters the system's TCP/IP stack and modifies packets in ICMP error messages in a way that allows remote attackers to determine that the system is running PGPfire.
CVE-2003-0078 4 Freebsd, Openbsd, Openssl and 1 more 6 Freebsd, Openbsd, Openssl and 3 more 2025-04-03 N/A
ssl3_get_record in s3_pkt.c for OpenSSL before 0.9.7a and 0.9.6 before 0.9.6i does not perform a MAC computation if an incorrect block cipher padding is used, which causes an information leak (timing discrepancy) that may make it easier to launch cryptographic attacks that rely on distinguishing between padding and MAC verification errors, possibly leading to extraction of the original plaintext, aka the "Vaudenay timing attack."
CVE-2001-1387 2 Netfilter, Redhat 2 Iptables, Linux 2025-04-03 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-2002-2094 1 Joetesta 1 Hellbent 2025-04-03 N/A
Joe Testa hellbent 01 allows remote attackers to determine the full path of the web root directory via a GET request with a relative path that includes the root's parent, which generates a 403 error message if the parent is incorrect, but a normal response if the parent is correct.
CVE-2004-2252 1 Sophos 1 Astaro Security Linux 2025-04-03 N/A
The firewall in Astaro Security Linux before 4.024 sends responses to SYN-FIN packets, which makes it easier for remote attackers to obtain information about the system and construct specialized attacks.
CVE-2001-1528 1 Amtote 1 Homebet 2025-04-03 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-2025-21336 1 Microsoft 15 Windows 10 1507, Windows 10 1607, Windows 10 1809 and 12 more 2025-04-02 5.6 Medium
Windows Cryptographic Information Disclosure Vulnerability
CVE-2024-54767 2025-04-02 7.5 High
An access control issue in the component /juis_boxinfo.xml of AVM FRITZ!Box 7530 AX v7.59 allows attackers to obtain sensitive information without authentication. NOTE: this is disputed by the Supplier because it cannot be reproduced, and the issue report focuses on an unintended configuration with direct Internet exposure.
CVE-2025-27667 1 Printerlogic 2 Vasion Print, Virtual Appliance 2025-04-01 9.8 Critical
Vasion Print (formerly PrinterLogic) before Virtual Appliance Host 22.0.843 Application 20.0.1923 allows Administrative User Email Enumeration OVE-20230524-0011.
CVE-2024-51477 1 Ibm 1 Infosphere Information Server 2025-04-01 4.3 Medium
IBM InfoSphere Information Server 11.7 could allow an authenticated to obtain sensitive username information due to an observable response discrepancy.
CVE-2025-31124 2025-04-01 5.3 Medium
Zitadel is open-source identity infrastructure software. ZITADEL administrators can enable a setting called "Ignoring unknown usernames" which helps mitigate attacks that try to guess/enumerate usernames. If enabled, ZITADEL will show the password prompt even if the user doesn't exist and report "Username or Password invalid". While the setting was correctly respected during the login flow, the user's username was normalized leading to a disclosure of the user's existence. This vulnerability is fixed in 2.71.6, 2.70.8, 2.69.9, 2.68.9, 2.67.13, 2.66.16, 2.65.7, 2.64.6, and 2.63.9.
