Q1What is this vulnerability? (Essence + Consequences)
🚨 **Essence**: Erugo < 0.2.15 suffers from **insufficient path validation** during file sharing creation.…
🛡️ **Root Cause**: **CWE-22** (Path Traversal). The flaw lies in the **creation of shares**, where user-supplied paths are not adequately sanitized or validated before processing.
Q3Who is affected? (Versions/Components)
📦 **Affected**: **Erugo** (Open Source File Sharing Platform) by **ErugoOSS**. Specifically versions **0.2.14 and earlier**. 🚫 Not affected: v0.2.15+.
Q4What can hackers do? (Privileges/Data)
💀 **Attacker Capabilities**: With **no authentication required** (PR:N), attackers can upload malicious files to arbitrary system paths. This grants **full control** (C:H, I:H, A:H) via RCE.
🔍 **Public Exploit**: **No PoC provided** in the data. However, the vulnerability type (Path Traversal/RCE) is standard. Wild exploitation risk is **HIGH** due to simplicity.
Q7How to self-check? (Features/Scanning)
🔎 **Self-Check**: Scan for **Erugo** instances. Check version numbers. Look for file upload/share endpoints. Verify if path traversal payloads (e.g., `../../`) are blocked during share creation.
Q8Is it fixed officially? (Patch/Mitigation)
✅ **Official Fix**: **YES**. Patched in **v0.2.15**. 📝 Reference: GitHub commit `256bc63` and GHSA advisory `GHSA-336w-hgpq-6369`. Upgrade immediately!
Q9What if no patch? (Workaround)
🚧 **No Patch Workaround**: If upgrading is impossible, **disable file sharing features** if possible. Implement strict **WAF rules** to block path traversal sequences in upload parameters. Isolate the service.
Q10Is it urgent? (Priority Suggestion)
🔥 **Urgency**: **CRITICAL**. CVSS Score is **9.8** (High). RCE with no auth is a game-over scenario. **Priority 1**: Patch to v0.2.15 immediately.
