从这个网页截图中,可以获取到以下关于漏洞的关键信息: 1. 漏洞类型:Denial of service (DoS) via multipart/form-data 2. 漏洞描述: - Summary:Starlette treats multipart/form-data parts without a filename as text form fields and buffers those in byte strings with no size limit. This allows an attacker to upload arbitrary large form fields and cause Starlette to both slow down significantly due to excessive memory allocations and copy operations, and also consume more and more memory until the server starts swapping and grinds to a halt, or the OS terminates the server process with an OOM error. Uploading multiple such requests in parallel may be enough to render a service practically unusable, even if reasonable request size limits are enforced by a reverse proxy in front of Starlette. 3. PoC: 4. 影响: - This Denial of service (DoS) vulnerability affects all applications built with Starlette (or FastAPI) accepting form requests. 5. 漏洞严重性:High (8.7 / 10) 6. 受影响版本:<0.39.2 7. 已修复版本:0.40.0 8. CVSS v4 base metrics: - Attack Vector: Network - Attack Complexity: Low - Privileges Required: None - User Interaction: None - Vulnerable System Impact Metrics: - Confidentiality: None - Integrity: None - Availability: High - Subsequent System Impact Metrics: - Confidentiality: None - Integrity: None - Availability: None 9.
