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-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.

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-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-2001-1528 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.

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-2005-1650 1 Woppoware 1 Postmaster 2026-04-16 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-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-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-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-2025-47872 1 Eg4 Electronics 7 Eg4 12000xp, Eg4 12kpv, Eg4 18kpv and 4 more 2026-04-15 5.8 Medium
The public-facing product registration endpoint server responds differently depending on whether the S/N is valid and unregistered, valid but already registered, or does not exist in the database. Combined with the fact that serial numbers are sequentially assigned, this allows an attacker to gain information on the product registration status of different S/Ns.
CVE-2025-24391 1 Otrs 1 Otrs 2026-04-15 5.3 Medium
A vulnerability in the External Interface of OTRS allows conclusions to be drawn about the existence of user accounts through different HTTP response codes and messages.

CVE-2022-50800 1 H3c 1 Ssl Vpn 2026-04-15 7.5 High
H3C SSL VPN contains a user enumeration vulnerability that allows attackers to identify valid usernames through the 'txtUsrName' POST parameter. Attackers can submit different usernames to the login_submit.cgi endpoint and analyze response messages to distinguish between existing and non-existing accounts.
CVE-2024-54767 2026-04-15 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.
