CVE Vendors Products Updated CVSS v3.1
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-2001-1387 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-2003-0078 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-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-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-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-2001-1483 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-2004-0294 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-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-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-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-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-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-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-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-2024-54454 2026-04-15 5.3 Medium
An issue was discovered in Kurmi Provisioning Suite before 7.9.0.35, 7.10.x through 7.10.0.18, and 7.11.x through 7.11.0.15. An Observable Response Discrepancy vulnerability in the sendPasswordReinitLink action of the unlogged.do page allows remote attackers to test whether a username is valid or not. This allows confirmation of valid usernames.
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-2024-28885 2026-04-15 5.9 Medium
Observable discrepancy in some Intel(R) QAT Engine for OpenSSL software before version v1.6.1 may allow information disclosure via network access.
