Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: Directory Traversal in NcMonitorServer.exe. π **Consequences**: Attackers can read arbitrary files outside the web root. Critical data exposure risk!
Q2Root Cause? (CWE/Flaw)
π‘οΈ **CWE**: CWE-22 (Improper Limitation of a Pathname to a Restricted Directory). π **Flaw**: The server fails to sanitize path sequences like `../` or `..\` in URLs.
Q3Who is affected? (Versions/Components)
π’ **Vendor**: NComputing. π¦ **Product**: vSpace Pro. π **Affected**: Versions 10 and 11. βοΈ **Component**: NC Monitor Server (NcMonitorServer.exe).
Q4What can hackers do? (Privileges/Data)
π΅οΈ **Action**: Read arbitrary files. π **Target**: Files outside the web server root directory. π **Data**: Sensitive configs, logs, or system files. No credentials needed!
Q5Is exploitation threshold high? (Auth/Config)
π **Auth**: None required. π **Network**: TCP port 8667. π **Threshold**: LOW. Simple URL manipulation triggers the exploit. Easy to automate.
Q6Is there a public Exp? (PoC/Wild Exploitation)
π₯ **Exploit**: Yes. π **Source**: Exploit-DB #44497. π§ͺ **PoC**: Available via Nuclei templates. π **Status**: Publicly known and exploitable.
Q7How to self-check? (Features/Scanning)
π **Check**: Scan TCP 8667. π‘ **Tool**: Use Nuclei or custom scripts. π§ͺ **Test**: Send requests with `.../` or `..../` sequences. π **Indicator**: Look for file content in response.
π§ **Workaround**: Block TCP 8667 externally. π **Firewall**: Restrict access to internal networks only. π« **Service**: Disable NC Monitor Server if not needed.
Q10Is it urgent? (Priority Suggestion)
β‘ **Priority**: HIGH. π¨ **Urgency**: Critical due to no-auth requirement. π **Risk**: High impact data leakage. π **Action**: Patch NOW or isolate the port.
