CVE-2025-22137 — AI Deep Analysis Summary

🚨 **Essence**: Pingvin Share suffers from a **Code Issue** allowing arbitrary file overwrite via HTTP POST.…

🛡️ **Root Cause**: **CWE-20: Improper Input Validation**.…

👥 **Affected**: **Pingvin Share** by **stonith404**. 📦 **Versions**: **0.6.0** through **1.3.0**. 🌐 **Type**: Self-hosted file sharing platform. If you run these versions, you are vulnerable.

💀 **Attacker Actions**: Overwrite **arbitrary files** on the server. 📂 This can lead to: 1. **RCE** (if overwriting executable/config files). 2. **Data Theft** (if overwriting auth tokens). 3.…

⚡ **Exploitation Threshold**: **LOW**. 🚫 **Auth**: None required (PR:N). 🖱️ **UI**: None required (UI:N). 🌍 **Access**: Network (AV:N). 📶 **Complexity**: Low (AC:L).…

🔍 **Public Exploit**: No specific PoC code listed in the data (pocs: []). ⚠️ **However**: The vulnerability is well-defined (Arbitrary File Overwrite). Exploitation logic is straightforward for skilled attackers.…

🔎 **Self-Check**: 1. Check your Pingvin Share version (0.6.0 - 1.3.0). 2. Scan for HTTP POST requests to file upload endpoints. 3. Verify if file paths are sanitized against directory traversal (e.g., `../`).…

✅ **Fixed**: Yes. 📅 **Published**: 2025-01-08. 🔗 **Reference**: GitHub Security Advisory (GHSA-rjwx-p44f-mcrv) and commits `6cf5c66` & `c52ec71`. 🛠️ **Mitigation**: Update to the latest version immediately.…

🚧 **No Patch Workaround**: 1. **Isolate**: Restrict network access to Pingvin Share (firewall). 2. **Disable**: Temporarily disable the file upload feature if possible. 3.…

🔥 **Urgency**: **CRITICAL**. 🚨 CVSS Score is **High** (H/I/H/A). 🏃 **Priority**: Immediate patching required. Since it requires no auth and allows arbitrary file overwrite, the risk of compromise is imminent.…
