Vulnerability Data

A Regular Expression Denial of Service (ReDoS) vulnerability exists in gaizhenbiao/chuanhuchatgpt, as of commit 20b2e02. The server uses the regex pattern `r'<[^>]+>'` to parse user input. In Python's default regex engine, this pattern can take polynomial time to match certain…

crafted inputs. An attacker can exploit this by uploading a malicious JSON payload, causing the server to consume 100% CPU for an extended period. This can lead to a Denial of Service (DoS) condition, potentially affecting the entire server.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SA-11 Developer Testing and Evaluation good match

Developer testing and evaluation can discover inefficient regex patterns via performance or static analysis.

SA-15 Development Process, Standards, and Tools partial match

Development standards and tools can require safe regex construction and forbid known exponential patterns.

SC-5 Denial-of-service Protection partial match

Denial-of-service protections limit resource exhaustion caused by expensive regex evaluation.

SI-10 Information Input Validation partial match

Input validation can constrain data that would otherwise trigger worst-case regex complexity.
