CyberRota Analysis

AI-Generated

The vulnerability allows unauthenticated attackers to exploit the OAuth2 login handler in OliveTin versions 3000.0.0 to 3000.17.0 by flooding the registeredStates map with requests, leading to memory exhaustion and a denial of service. Organizations using affected versions should prioritize upgrading to version 3000.17.0 to mitigate this high-severity risk. This issue is particularly critical for environments relying on OliveTin for authentication services.

Original NVD Description

OliveTin gives access to predefined shell commands from a web interface. From 3000.0.0 until 3000.17.0, the service/internal/auth/otoauth2/restapi_auth_oauth2.go OAuth2 login handler stores per-login state in the registeredStates map on every /oauth/login request without expiring, deleting, or bounding entries, allowing an unauthenticated attacker to exhaust memory and cause a denial of service. This issue is fixed in version 3000.17.0.
