Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: A Code Injection flaw in the `bassmaster` plugin for Node.js `hapi`. <br>π₯ **Consequences**: Remote attackers can execute arbitrary JavaScript code, leading to full **Remote Code Execution (RCE)**.β¦
π‘οΈ **Root Cause**: Improper handling of user input in `lib/batch.js`. <br>π **Flaw**: The `internals.batch` function uses `eval()` on data that isn't properly sanitized.β¦
π¦ **Affected Component**: `bassmaster` plugin for `hapi` server framework (Node.js). <br>π **Versions**: All versions **β€ 1.5.1** are vulnerable. Versions 1.5.2+ are likely safe.
Q4What can hackers do? (Privileges/Data)
π **Privileges**: Full **Remote Code Execution**. <br>π **Data Impact**: Attackers can run any JavaScript command on the server.β¦
β‘ **Threshold**: **LOW**. <br>π **Auth**: No authentication required. <br>βοΈ **Config**: Exploitable remotely via the plugin's batch processing interface. Just sending a crafted request is enough.
Q6Is there a public Exp? (PoC/Wild Exploitation)
π£ **Public Exp?**: **YES**. <br>π **PoCs**: Available on GitHub (e.g., `bassmaster-rce`, `CVE-2014-7205`). Includes Python scripts for **NC reverse shells** and **NodeJS reverse shells**. Exploit-DB ID: 40689.
Q7How to self-check? (Features/Scanning)
π **Self-Check**: Scan your `package.json` or `node_modules`. <br>π **Feature**: Look for `bassmaster` dependency. <br>π οΈ **Tool**: Use npm audit or manual version check. If version is `1.5.1` or lower, you are at risk.
π₯ **Urgency**: **CRITICAL**. <br>β³ **Priority**: **P0**. <br>π‘ **Reason**: RCE with public exploits and no auth required. Patch immediately to prevent server takeover.
