| CVE-2026-27630 | 2 Maximmasiutin, Ritlabs | 2 Tinyweb, Tinyweb | 2026-02-28 | 7.5 High |
| TinyWeb is a web server (HTTP, HTTPS) written in Delphi for Win32. Versions prior to version 2.02 are vulnerable to a Denial of Service (DoS) attack known as Slowloris. The server spawns a new OS thread for every incoming connection without enforcing a maximum concurrency limit or an appropriate request timeout. An unauthenticated remote attacker can exhaust server concurrency limits and memory by opening numerous connections and sending data exceptionally slowly (e.g. 1 byte every few minutes). Anyone hosting services using TinyWeb is impacted. Version 2.02 fixes the issue. The patch introduces a `CMaxConnections` limit (set to 512) and a `CConnectionTimeoutSecs` idle timeout (set to 30 seconds). As a temporary workaround if upgrading is not immediately possible, consider placing the server behind a robust reverse proxy or Web Application Firewall (WAF) such as nginx, HAProxy, or Cloudflare, configured to buffer incomplete requests and aggressively enforce connection limits and timeouts. | ||||
| CVE-2026-27633 | 2 Maximmasiutin, Ritlabs | 2 Tinyweb, Tinyweb | 2026-02-28 | 7.5 High |
| TinyWeb is a web server (HTTP, HTTPS) written in Delphi for Win32. Versions prior to version 2.02 have a Denial of Service (DoS) vulnerability via memory exhaustion. Unauthenticated remote attackers can send an HTTP POST request to the server with an exceptionally large `Content-Length` header (e.g., `2147483647`). The server continuously allocates memory for the request body (`EntityBody`) while streaming the payload without enforcing any maximum limit, leading to all available memory being consumed and causing the server to crash. Anyone hosting services using TinyWeb is impacted. Version 2.02 fixes the issue. The patch introduces a `CMaxEntityBodySize` limit (set to 10MB) for the maximum size of accepted payloads. As a temporary workaround if upgrading is not immediately possible, consider placing the server behind a Web Application Firewall (WAF) or reverse proxy (like nginx or Cloudflare) configured to explicitly limit the maximum allowed HTTP request body size (e.g., `client_max_body_size` in nginx). | ||||
| CVE-2024-5193 | 1 Ritlabs | 1 Tinyweb | 2026-01-05 | 5.3 Medium |
| A security vulnerability has been detected in Ritlabs TinyWeb Server 1.94. This vulnerability affects unknown code of the component Request Handler. The manipulation with the input %0D%0A leads to crlf injection. It is possible to initiate the attack remotely. The exploit has been disclosed publicly and may be used. Upgrading to version 1.99 is able to resolve this issue. The identifier of the patch is d49c3da6a97e950975b18626878f3ee1f082358e. It is suggested to upgrade the affected component. The vendor was contacted early about this disclosure but did not respond in any way. | ||||
| CVE-2024-34199 | 1 Ritlabs | 1 Tinyweb | 2025-06-13 | 8.6 High |
| TinyWeb 1.94 and below allows unauthenticated remote attackers to cause a denial of service (Buffer Overflow) when sending excessively large elements in the request line. | ||||
