Q1What is this vulnerability? (Essence + Consequences)
๐จ **Reflected XSS Vulnerability**: OpenCTI 3.3.1 does not sanitize query strings at the `/graphql` endpoint, allowing attackers to inject JavaScript code.โฆ
๐ **Root Cause**: CWE-79 (Improper Input Validation). โ No XSS escaping applied to parameters after `?`, enabling direct execution of malicious JS. ๐ ๏ธ Vulnerable Point: GraphQL interface lacks security filtering.
Q3Who is affected? (Versions/Components)
๐ฏ **Affected Version**: OpenCTI 3.3.1. ๐ฆ **Component**: Frontend web interface (exposed via `/graphql`). โ Verified on Linux Mint & Windows 10.
Q4What can hackers do? (Privileges/Data)
๐ **What Attackers Can Do**: Execute arbitrary JavaScript in users' browsers. ๐ Includes: session theft, redirection, phishing pop-ups. โ ๏ธ No direct server access, but user sessions can be hijacked.
Q5Is exploitation threshold high? (Auth/Config)
โ ๏ธ **Low Exploitation Barrier**: No authentication required! โ Simply craft a malicious URL; user click triggers attack. ๐ Attackers can lure users to malicious links.
Q6Is there a public Exp? (PoC/Wild Exploitation)
๐ ๏ธ **Exploit Available**: ExploitDB #48595 provides PoC. ๐ Example: `/graphql?'"--></style></scRipt><scRipt>alert('Raif_Berkay')</scRipt>`. โ ๏ธ No known in-the-wild exploitation reported.
Q7How to self-check? (Features/Scanning)
๐ **Self-Check Method**: Verify if `/graphql` accepts arbitrary query parameters. ๐งช Test with payload: `?x=<script>alert(1)</script>`. โ If alert appears, vulnerability exists.
Q8Is it fixed officially? (Patch/Mitigation)
โ **Official Fix Available**: OpenCTI GitHub repository contains fix records (specific version not provided). ๐ก๏ธ Recommended: Upgrade to latest version.
Q9What if no patch? (Workaround)
๐ก๏ธ **Temporary Mitigation**: 1. Disable `/graphql` endpoint (if not essential). 2. Use WAF to block `<script>` tags. 3. HTML-escape query parameters.
Q10Is it urgent? (Priority Suggestion)
๐ฅ **High Priority!** CVSS 5.4 (Medium), but due to no authentication required and trigger on user click, real-world risk is high. ๐ Recommend immediate fix or temporary mitigation.
