Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: GoCast 1.1.3 suffers from **OS Command Injection**. π **Consequences**: Attackers can execute **arbitrary commands** on the host system.β¦
π‘οΈ **Root Cause**: **CWE-78** (Improper Neutralization of Special Elements). The flaw lies in the **NAT parameter** handling. User input is not sanitized before being passed to the OS shell.
Q3Who is affected? (Versions/Components)
π₯ **Affected**: **GoCast** by developer **mayuresh82**. Specifically **Version 1.1.3**. It is a tool for controlling BGP route announcements from the host.
Q4What can hackers do? (Privileges/Data)
π **Impact**: **Full System Compromise**. CVSS Score is **Critical (9.8)**. Attackers gain **High Confidentiality, Integrity, and Availability** impact. Essentially, **Root/Admin access** via command execution.
Q5Is exploitation threshold high? (Auth/Config)
β‘ **Threshold**: **LOW**. CVSS Vector: **AV:N/AC:L/PR:N/UI:N**. No authentication required. No user interaction needed. Exploitable over the **Network** with **Low Complexity**.
Q6Is there a public Exp? (PoC/Wild Exploitation)
π **Public Exp?**: The provided data lists **POCs as empty** `[]`. However, the vulnerability is well-documented by **Talos Intelligence** (TALOS-2024-1961). Wild exploitation risk is **HIGH** due to low barrier.
Q7How to self-check? (Features/Scanning)
π **Self-Check**: Scan for **GoCast v1.1.3**. Look for BGP routing tools exposing **NAT parameters**. Use fuzzing tools to inject shell metacharacters (`;`, `|`, `&`) into NAT fields to test for command execution.
π§ **No Patch?**: **Input Validation**: Strictly whitelist characters in NAT parameters. **Network Segmentation**: Isolate the BGP control interface. **Disable** the tool if not actively used for BGP routing.
Q10Is it urgent? (Priority Suggestion)
π₯ **Urgency**: **CRITICAL**. CVSS 9.8. Remote Code Execution (RCE) with no auth. **Patch Immediately**. Prioritize this over most other vulnerabilities due to the ease of exploitation and severity of impact.
