An Information Exposure issue (issue 2 of 2) was discovered in GitLab Community and Enterprise Edition before 11.7.8, 11.8.x before 11.8.4, and 11.9.x before 11.9.2. During the OAuth authentication process, the application attempts to validate a parameter in an insecure way, potentially exposing data.

Symfony is a PHP framework for web and console applications and a set of reusable PHP components. The ability to enumerate users was possible without relevant permissions due to different handling depending on whether the user existed or not when attempting to use the switch users functionality. We now ensure that 403s are returned whether the user exists or not if a user cannot switch to a user or if the user does not exist. The patch for this issue is available for branch 3.4.

An exposure of sensitive information vulnerability exists in TCExam <= 14.8.1. If a password reset request was made for an email address that was not registered with a user then we would be presented with an ‘unknown email’ error. If an email is given that is registered with a user then this error will not appear. A malicious actor could abuse this to enumerate the email addresses of

Computrols CBAS 18.0.0 allows Username Enumeration.

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.

LabVantage LIMS 8.3 does not properly maintain the confidentiality of database names. For example, the web application exposes the database name. An attacker might be able to enumerate database names by providing his own database name in a request, because the response will return an 'Unrecognized Database exception message if the database does not exist.

An issue was discovered in One Identity Password Manager 5.8. An attacker could enumerate valid answers for a user. It is possible for an attacker to detect a valid answer based on the HTTP response content, and reuse this answer later for a password reset on a chosen password. The enumeration is possible because, within the HTTP response content, WRONG ID is only returned when the answer is incorrect.

An issue was discovered in UTI Mutual fund Android application 5.4.18 and prior, allows attackers to brute force enumeration of usernames determined by the error message returned after invalid credentials are attempted.

In Legion of the Bouncy Castle BC before 1.61 and BC-FJA before 1.0.1.2, attackers can obtain sensitive information about a private exponent because of Observable Differences in Behavior to Error Inputs. This occurs in org.bouncycastle.crypto.encodings.OAEPEncoding. Sending invalid ciphertext that decrypts to a short payload in the OAEP Decoder could result in the throwing of an early exception, potentially leaking some information about the private exponent of the RSA private key performing the encryption.

Zabbix through 4.4.0alpha1 allows User Enumeration. With login requests, it is possible to enumerate application usernames based on the variability of server responses (e.g., the "Login name or password is incorrect" and "No permissions for system access" messages, or just blocking for a number of seconds). This affects both api_jsonrpc.php and index.php.

Pritunl 1.29.2145.25 allows attackers to enumerate valid VPN usernames via a series of /auth/session login attempts. Initially, the server will return error 401. However, if the username is valid, then after 20 login attempts, the server will start responding with error 400. Invalid usernames will receive error 401 indefinitely. Note: This has been disputed by the vendor as not a vulnerability. They argue that this is an intended design

Umanni RH 1.0 has a user enumeration vulnerability. This issue occurs during password recovery, where a difference in messages could allow an attacker to determine if the user is valid or not, enabling a brute force attack with valid users.

ECDSA/EC/Point.pm in Crypt::Perl before 0.33 does not properly consider timing attacks against the EC point multiplication algorithm.

A user enumeration vulnerability flaw was found in Venki Supravizio BPM 10.1.2. This issue occurs during password recovery, where a difference in error messages could allow an attacker to determine if a username is valid or not, enabling a brute-force attack with valid usernames.

In the Voatz application 2020-01-01 for Android, the amount of data transmitted during a single voter's vote depends on the different lengths of the metadata across the available voting choices, which makes it easier for remote attackers to discover this voter's choice by sniffing the network. For example, a small amount of sniffed data may indicate that a vote was cast for the candidate with the least metadata. An active man-in-the-middle attacker can leverage this behavior to disrupt voters' abilities to vote for a candidate opposed by the attacker.

Proxmox VE prior to 3.2: 'AccessControl.pm' User Enumeration Vulnerability

An issue was discovered in Aviatrix Controller before 5.4.1204. There is a Observable Response Discrepancy from the API, which makes it easier to perform user enumeration via brute force.

An issue was discovered in AvertX Auto focus Night Vision HD Indoor/Outdoor IP Dome Camera HD838 and Night Vision HD Indoor/Outdoor Mini IP Bullet Camera HD438. Failed web UI login attempts elicit different responses depending on whether a user account exists. Because the responses indicate whether a submitted username is valid or not, they make it easier to identify legitimate usernames. If a login request is sent to ISAPI/Security/sessionLogin/capabilities using a username that exists, it will return the value of the salt given to that username, even if the password is incorrect. However, if a login request is sent using a username that is not present in the database, it will return an empty salt value. This allows attackers to enumerate legitimate usernames, facilitating brute-force attacks. NOTE: this is different from CVE-2020-7057.

Fixed in v1.5.1, Argo version v1.5.0 was vulnerable to a user-enumeration vulnerability which allowed attackers to determine the usernames of valid (non-SSO) accounts because /api/v1/session returned 401 for an existing username and 404 otherwise.
