CVE-2017-6527 — AI Deep Analysis Summary

🚨 **Essence**: A critical security flaw in **dnaTools dnaLIMS**. <br>💥 **Consequences**: Attackers can bypass controls and gain unauthorized access to **system files**.…

🛡️ **Root Cause**: The vulnerability lies in the **`viewAppletFsa.cgi`** script. Specifically, the **`seqID`** parameter is not properly sanitized.…

🏢 **Vendor**: dnaTools (USA). <br>📦 **Product**: dnaLIMS (DNA Data Analysis Tool). <br>📅 **Affected Version**: **4-2015s13** and potentially earlier versions.

🕵️ **Attacker Action**: Exploit the `seqID` parameter. <br>🔓 **Privileges**: Gain **read access** to arbitrary system files. <br>📂 **Data Impact**: Sensitive DNA data or server configuration files may be exposed.

🔑 **Threshold**: **Low to Medium**. <br>🌐 **Access**: Likely requires network access to the web interface.…

💣 **Public Exploit**: **YES**. <br>📜 **References**: Exploit-DB ID **41578** is available. <br>🌍 **Status**: Active exploitation tools exist in the wild.

🔍 **Self-Check**: Scan for the presence of **`viewAppletFsa.cgi`**. <br>🧪 **Test**: Attempt to manipulate the **`seqID`** parameter with path traversal characters (e.g., `../`).…

🩹 **Fix**: Check for official patches from **dnaTools**. <br>📉 **Mitigation**: If no patch, disable the `viewAppletFsa.cgi` endpoint if possible. <br>🔗 **Source**: Refer to Shorebreak Security advisory for details.

🚧 **No Patch Workaround**: <br>1️⃣ **Network Segmentation**: Restrict access to the dnaLIMS server. <br>2️⃣ **WAF Rules**: Block requests containing path traversal sequences in `seqID`.…

🔥 **Urgency**: **HIGH**. <br>⏳ **Priority**: Immediate action required. <br>📢 **Reason**: Public exploits exist, and the impact involves sensitive system file access. Do not delay patching or mitigation.
