Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: Remote Command Injection in Citrix SD-WAN Center. π₯ **Consequences**: Attackers can execute arbitrary OS commands, leading to full system compromise, data theft, or unauthorized modifications.
Q2Root Cause? (CWE/Flaw)
π‘οΈ **Root Cause**: CWE-78 (OS Command Injection). The `DiagnosticsController` ping function fails to sanitize HTTP parameters (`ipAddress`, `pingCount`, `packetSize`) before constructing shell commands.
Q3Who is affected? (Versions/Components)
π¦ **Affected Versions**: β’ Citrix SD-WAN Center 10.2.x (before 10.2.3) β’ NetScaler SD-WAN Center 10.0.x (before 10.0.8) π’ **Vendor**: Citrix Systems
Q4What can hackers do? (Privileges/Data)
π΅οΈ **Attacker Capabilities**: β’ Execute unauthorized OS commands β’ Obtain sensitive system information β’ Modify critical data β’ Perform unauthorized operations on the network infrastructure
Q5Is exploitation threshold high? (Auth/Config)
β οΈ **Exploitation Threshold**: **LOW**. The vulnerability is triggered via HTTP requests routed through the Collector controller.β¦
π» **Public Exploit**: **YES**. Proof-of-Concept (PoC) available via Nuclei templates (projectdiscovery/nuclei-templates). Active exploitation is possible using crafted HTTP parameters.
Q7How to self-check? (Features/Scanning)
π **Self-Check**: β’ Scan for specific HTTP endpoints related to `DiagnosticsController`. β’ Use Nuclei templates to test for injection in `ipAddress`, `pingCount`, or `packetSize` fields. β’ Check version numbers against β¦
π§ **No Patch Workaround**: β’ Restrict network access to the SD-WAN Center management interface. β’ Implement WAF rules to block shell metacharacters in HTTP parameters. β’ Disable the ping/diagnostics function if not striβ¦
π₯ **Urgency**: **CRITICAL**. Remote Code Execution (RCE) vulnerabilities in network management centers are high-priority. Immediate patching is recommended to prevent total infrastructure takeover.
