CVSS v3.1 |
| 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. |
| 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. |
| 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. |
| An issue in Sourcebans++ before v.1.8.0 allows a remote attacker to obtain sensitive information via a crafted XAJAX call to the Forgot Password function. |
| 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. |
| 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. |
| CWE-203: Observable Discrepancy |
| Due to improper authentication mechanism an unauthenticated remote attacker can enumerate valid usernames. |
| A specific authentication strategy allows to learn ids of PAM users associated with certain authentication types. |
| Observable discrepancy in RAPL interface for some Intel(R) Processors may allow a privileged user to potentially enable information disclosure via local access. |
| A potential security vulnerability has been reported in the system BIOS of certain HP PC products, which might allow memory tampering. HP is releasing mitigation for the potential vulnerability. |
| Accounts enumeration vulnerability in the Login Component of Reolink Duo 2 WiFi Camera (Firmware Version v3.0.0.1889_23031701) allows remote attackers to determine valid user accounts via login attempts. This can lead to the enumeration of user accounts and potentially facilitate other attacks, such as brute-forcing of passwords. The vulnerability arises from the application responding differently to login attempts with valid and invalid usernames. |
| 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. |
| Helix ALM prior to 2025.1 returns distinct error responses during authentication, allowing an attacker to determine whether a username exists. |
| 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. |
| 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. |
| 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. This enables an attacker to systematically identify valid email addresses.
This issue affects:
* OTRS 7.0.X
* OTRS 8.0.X
* OTRS 2023.X
* OTRS 2024.X
* OTRS 2025.X |
| 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. |
| 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. |
| User enumeration vulnerability in /pwreset.php in osTicket v1.18.2 allows remote attackers to enumerate valid usernames registered in the platform. |
