Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: VICIDIAL dialer suffers from **Command Injection**. π **Consequences**: Remote attackers can execute **arbitrary commands** on the server. Itβs a critical security breach for call center systems.
Q2Root Cause? (CWE/Flaw)
π‘οΈ **Root Cause**: **Input Validation Flaw**. Specifically, the `extension` parameter in `manager_send.php` fails to sanitize **shell meta-characters**.β¦
π¦ **Affected Versions**: - VICIDIAL dialer **2.8-403a** and earlier. - Version **2.7**. - Version **2.7RC1**. β οΈ Based on Asterisk GUI client architecture.
Q4What can hackers do? (Privileges/Data)
π **Attacker Capabilities**: - Execute **arbitrary commands** remotely. - Potential full system compromise depending on service privileges. - No specific data theft mentioned, but **control** is the primary risk.
Q5Is exploitation threshold high? (Auth/Config)
π **Exploitation Threshold**: **Low**. The vulnerability is triggered via a specific script parameter (`manager_send.php`). It implies remote accessibility to this endpoint is sufficient.β¦
π **Public Exploit**: **YES**. - Exploit-DB ID: **29513**. - Discussed in **oss-security** mailing lists (Oct 2013). - Wild exploitation is possible given the public PoC.
Q7How to self-check? (Features/Scanning)
π **Self-Check**: 1. Scan for `manager_send.php` endpoint. 2. Check VICIDIAL version against affected list (2.7, 2.8-403a). 3. Look for unpatched Asterisk GUI client installations.
π§ **Workaround (No Patch)**: - **Block access** to `manager_send.php` externally. - Implement **WAF rules** to block shell meta-characters in the `extension` parameter.β¦
π₯ **Urgency**: **HIGH**. - Remote Code Execution (RCE) is present. - Public exploits exist. - Call center systems are high-value targets. - **Action**: Patch immediately or apply strict network controls.
