Frequently asked questions
Related CVEs
DataBuff ai-apm-web through 0.1.10 contains a hard-coded default credentials vulnerability that allows unauthenticated attackers to gain administrator access using the built-in admin/Databuff@123 account. Attackers can POST these credentials to /webapi/api/v1/auth/login to obtain an administrator token and access all protected /webapi routes.
DB-GPT through 0.8.2 contains a hardcoded credentials vulnerability in its default docker-compose.yml that sets a static MYSQL_ROOT_PASSWORD and publishes port 3306 on all interfaces. Attackers reaching port 3306 or the shared dbgptnet network can authenticate as root@% to gain full database access including FILE and SUPER privileges.
Tattile Smart+, Vega, and Basic device families firmware versions 1.181.5 and prior ship with default credentials that are not forced to be changed during installation or commissioning. An attacker who can reach the management interface can authenticate using the default credentials and gain administrative access, enabling unauthorized access to device configuration and data.
Vanus 0.8.0 through 0.9.0 contains a default credentials vulnerability that allows unauthenticated remote attackers to gain cluster-admin access by using the hardcoded admin token. Attackers can send the fixed Bearer token to the gateway gRPC proxy port to manage namespaces, eventbuses, users, tokens, and role bindings, and read or publish events.
JuggleIM im-server through 1.8.16 ships default administrator credentials admin/123456 that allow unauthenticated remote attackers to access the admin console on port 8090. Attackers can log in as administrator, even after account deletion since CheckLogin recreates it, to control tenant applications and app secrets.
JAIOTlink C492A-W6 Wi-Fi IP cameras running firmware 4.8.30.57701411 contain a hard-coded credentials vulnerability that allows network-adjacent attackers to gain unauthorized access by using the default admin username with an empty password accepted by the anyka_ipc HTTP service on port 80. Attackers can authenticate with these hardcoded credentials to access camera snapshots, video streams, network configuration, and factory-level API endpoints including the SetMAC command injection surface.
