CVE Vendors Products Updated CVSS v3.1
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-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-2004-1428 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-2003-0078 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-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.
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-2002-0208 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-2004-2252 1 Sophos 1 Astaro Security Linux 2026-04-16 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-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-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-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-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-2001-1483 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-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-2024-41880 1 Veilid 1 Veilid 2026-04-15 5.3 Medium
In veilid-core in Veilid before 0.3.4, the protocol's ping function can be misused in a way that decreases the effectiveness of safety and private routes.
CVE-2025-6386 1 Parisneo 1 Lollms 2026-04-15 N/A
The parisneo/lollms repository is affected by a timing attack vulnerability in the `authenticate_user` function within the `lollms_authentication.py` file. This vulnerability allows attackers to enumerate valid usernames and guess passwords incrementally by analyzing response time differences. The affected version is the latest, and the issue is resolved in version 20.1. The vulnerability arises from the use of Python's default string equality operator for password comparison, which compares characters sequentially and exits on the first mismatch, leading to variable response times based on the number of matching initial characters.
CVE-2025-13912 1 Wolfssl 1 Wolfssl 2026-04-15 N/A
Multiple constant-time implementations in wolfSSL before version 5.8.4 may be transformed into non-constant-time binary by LLVM optimizations, which can potentially result in observable timing discrepancies and lead to information disclosure through timing side-channel attacks.
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.
