CVSS v3.1 |
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
| An unauthenticated remote attacker can gain access to sensitive information including authentication information when using CODESYS OPC UA Server with the non-default Basic128Rsa15 security policy. |
| 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. |
| OpenSSH 9.5 through 9.7 before 9.8 sometimes allows timing attacks against echo-off password entry (e.g., for su and Sudo) because of an ObscureKeystrokeTiming logic error. Similarly, other timing attacks against keystroke entry could occur. |
| SummaryThis advisory addresses a security vulnerability in Mautic related to the "Forget your password" functionality. This vulnerability could be exploited by unauthenticated users to enumerate valid usernames.
User Enumeration via Timing Attack: A user enumeration vulnerability exists in the "Forget your password" functionality. Differences in response times for existing and non-existing users, combined with a lack of request limiting, allow an attacker to determine the existence of usernames through a timing-based attack.
MitigationPlease update to a version that addresses this timing vulnerability, where password reset responses are normalized to respond at the same time regardless of user existence. |
| An issue was discovered in Bouncy Castle Java TLS API and JSSE Provider before 1.78. Timing-based leakage may occur in RSA based handshakes because of exception processing. |
| A vulnerability classified as problematic was found in funnyzpc Mee-Admin up to 1.6. This vulnerability affects unknown code of the file /mee/login of the component Login. The manipulation of the argument username leads to observable response discrepancy. The attack can be initiated remotely. The complexity of an attack is rather high. The exploitation appears to be difficult. The exploit has been disclosed to the public and may be used. |
| 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. |
| Description: VMware NSX contains a username enumeration vulnerability. An unauthenticated malicious actor may exploit this to enumerate valid usernames, potentially leading to unauthorized access attempts.
Impact: Username enumeration → facilitates unauthorized access.
Attack Vector: Remote, unauthenticated.
Severity: Important.
CVSSv3: 7.5 (High).
Acknowledgments: Reported by the National Security Agency.
Affected Products:
* VMware NSX 9.x.x.x, 4.2.x, 4.1.x, 4.0.x
* NSX-T 3.x
* VMware Cloud Foundation (with NSX) 5.x, 4.5.x
Fixed Versions:
* NSX 9.0.1.0; 4.2.2.2/4.2.3.1 http://4.2.2.2/4.2.3.1 ; 4.1.2.7; NSX-T 3.2.4.3; CCF async patch (KB88287).
Workarounds: None. |
| A timing-based side-channel flaw exists in the perl-Crypt-OpenSSL-RSA package, which could be sufficient to recover plaintext across a network in a Bleichenbacher-style attack. To achieve successful decryption, an attacker would have to be able to send a large number of trial messages. The vulnerability affects the legacy PKCS#1v1.5 RSA encryption padding mode. |
