OliveTin Web Interface Authentication Issues

OliveTin versions prior to 3000.11.0 suffer from broken access control allowing unauthenticated users to invoke the KillAction RPC endpoint and terminate running shell command executions, bypassing authentication restrictions. Public exploit code exists for this vulnerability, enabling remote denial of service attacks against legitimate administrative actions. The vulnerability affects OliveTin deployments regardless of authentication settings and has been remediated in version 3000.11.0 and later.

OliveTin versions prior to 3000.10.3 are vulnerable to unauthenticated denial-of-service attacks when OAuth2 authentication is enabled, allowing remote attackers to crash the application by sending concurrent requests to the login endpoint. The vulnerability stems from unsynchronized access to shared state during OAuth2 processing, triggering a Go runtime panic. Public exploit code exists for this high-severity flaw, which is patched in version 3000.10.3 and later.

OliveTin versions prior to 3000.10.2 are vulnerable to unauthenticated denial of service through the PasswordHash API endpoint, which lacks request throttling or authentication controls and allows attackers to trigger excessive memory allocation via concurrent hashing requests. An attacker can exhaust container memory by sending multiple parallel requests, causing service degradation or complete outage. Public exploit code exists for this vulnerability, and a patch is available in version 3000.10.2 and later.
