OliveTin gives access to predefined shell commands from a web interface. Prior to version 3000.10.2, the PasswordHash API endpoint allows unauthenticated users to trigger excessive memory allocation by sending concurrent password hashing requests. By issuing multiple parallel requests, an attacker can exhaust available container memory, leading to service degradation or complete denial of service (DoS). The issue occurs because the endpoint performs computationally and memory-intensive hashing operations without request throttling, authentication requirements, or resource limits. This issue has been patched in version 3000.10.2.
AnalysisAI
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.
Technical ContextAI
Classified as CWE-400 (Uncontrolled Resource Consumption). Affects Olivetin. OliveTin gives access to predefined shell commands from a web interface. Prior to version 3000.10.2, the PasswordHash API endpoint allows unauthenticated users to trigger excessive memory allocation by sending concurrent password hashing requests. By issuing multiple parallel requests, an attacker can exhaust available container memory, leading to service degradation or complete denial of service (DoS).

RemediationAI
A vendor patch is available — apply it immediately. Fixed in version 3000.10.2.. Restrict network access to the affected service where possible.
