Improper Restriction of Excessive Authentication Attempts, Weak Password Recovery Mechanism for Forgotten Password vulnerability in Birebirsoft Software and Technology Solutions Sufirmam allows Brute Force, Password Recovery Exploitation.This issue affects Sufirmam: through 23012026. NOTE: The vendor was contacted early about this disclosure but did not respond in any way.
Dell PowerScale OneFS versions prior to 9.13.0.0 contains an improper restriction of excessive authentication attempts vulnerability. An unauthenticated attacker with remote access could potentially exploit this vulnerability, leading to Unauthorized access.
Medtronic CareLink Network allows an unauthenticated remote attacker to perform a brute force attack on an API endpoint that could be used to determine a valid password under certain circumstances. This issue affects CareLink Network: before December 4, 2025.
The application does not implement sufficient measures to prevent multiple failed authentication attempts within a short time frame, making it possible for an attacker to guess user credentials.
In ExtremeGuest Essentials before 25.5.0, captive-portal may permit unauthorized access via manual brute-force procedure. Under certain ExtremeGuest Essentials captive-portal SSID configurations, repeated manual login attempts may allow an unauthenticated device to be marked as authenticated and obtain network access. Client360 logs may display the client MAC as the username despite no MAC-authentication being enabled.
