Q1What is this vulnerability? (Essence + Consequences)
๐จ **Essence**: Butterfly (OpenRefine module) mishandles the `file://` protocol in URLs. ๐ **Consequences**: Path Traversal, SSRF, and XSS attacks. Critical integrity loss!
Q2Root Cause? (CWE/Flaw)
๐ก๏ธ **Root Cause**: CWE-36 (Relative Path Traversal). The framework fails to sanitize or validate file paths derived from URL inputs. ๐ **Flaw**: Improper handling of `file` protocol schemes.
Q3Who is affected? (Versions/Components)
๐ข **Vendor**: OpenRefine. ๐ฆ **Product**: simile-butterfly. โ ๏ธ **Affected**: Versions **prior to 1.2.6**. If you are on 1.2.5 or lower, you are at risk!
Q4What can hackers do? (Privileges/Data)
๐ **Attacker Actions**:
1. Read arbitrary server files (Path Traversal).
2. Force server to make requests to internal networks (SSRF).
3. Inject malicious scripts (XSS).โฆ
๐ **Public Exp?**: No specific PoC code provided in the data. However, the vulnerability type (Path Traversal/SSRF) is well-known. Wild exploitation is likely possible for skilled attackers. ๐ต๏ธโโ๏ธ
Q7How to self-check? (Features/Scanning)
๐ **Self-Check**:
1. Check Butterfly version (< 1.2.6).
2. Scan for `file://` protocol usage in URL parameters.
3. Look for directory traversal patterns (`../`) in logs.
4.โฆ
๐ฅ **Urgency**: HIGH.
๐ **CVSS**: High severity (C:H, I:H).
๐ **Action**: Patch immediately. Remote, unauthenticated exploitation makes this a critical priority for any OpenRefine deployment.
