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-2002-2094 1 Joetesta 1 Hellbent 2026-04-16 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-2000-1117 1 Ibm 1 Lotus Notes 2026-04-16 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 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-2003-0078 4 Freebsd, Openbsd, Openssl and 1 more 6 Freebsd, Openbsd, Openssl and 3 more 2026-04-16 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-2001-1483 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-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-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-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-2002-0208 1 Network.associates 1 Pgpfire 2026-04-16 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-2003-0637 1 Novell 1 Ichain 2026-04-16 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-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-2004-0294 1 Yabbforumsoftware 1 Yet Another Bulletin Board 2026-04-16 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-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-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.
CVE-2020-10369 2026-04-15 5.5 Medium
Certain Cypress (and Broadcom) Wireless Combo chips, when a January 2021 firmware update is not present, allow inferences about memory content via a "Spectra" attack.
CVE-2020-10367 2026-04-15 5.5 Medium
Certain Cypress (and Broadcom) Wireless Combo chips, when a January 2021 firmware update is not present, allow memory access via a "Spectra" attack.
CVE-2025-46804 1 Gnu 1 Screen 2026-04-15 3.3 Low
A minor information leak when running Screen with setuid-root privileges allows unprivileged users to deduce information about a path that would otherwise not be available. Affected are older Screen versions, as well as version 5.0.0.
