Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: Issabel PBX 4.0.0 suffers from **OS Command Injection** via the `Asterisk-Cli` component.β¦
π‘οΈ **Root Cause**: **CWE-78** (OS Command Injection). <br>π **Flaw**: Improper handling of the `Command` parameter in `/index.php?menu=asterisk_cli`. Malicious input is passed directly to the OS without sanitization.
Q3Who is affected? (Versions/Components)
π’ **Affected**: **Issabel PBX** specifically version **4.0.0**. <br>π¦ **Component**: The `Asterisk-Cli` module is the vulnerable entry point.
Q4What can hackers do? (Privileges/Data)
π» **Attacker Capabilities**: <br>β’ Execute **any OS command** with the privileges of the web server. <br>β’ Create files, steal data, or pivot to other internal systems. <br>β’ Full control over the PBX infrastructure.
Q5Is exploitation threshold high? (Auth/Config)
π **Threshold**: **Medium**. <br>β οΈ **Requirement**: Requires **Authentication** (valid username/password). <br>π **CVSS**: `PR:H` (High Privileges Required) means you must be logged in first.
Q6Is there a public Exp? (PoC/Wild Exploitation)
π£ **Public Exploit**: **YES**. <br>π **PoC Available**: GitHub repos (e.g., `gunzf0x`) and Nuclei templates exist. <br>π₯ **Status**: Actively disclosed and usable by attackers.
Q7How to self-check? (Features/Scanning)
π **Self-Check**: <br>1. Scan for Issabel PBX 4.0.0 instances. <br>2. Look for the `/index.php?menu=asterisk_cli` endpoint. <br>3. Use Nuclei template `CVE-2024-0986.yaml` for automated detection.
π‘οΈ **Workaround**: <br>1. **Restrict Access**: Block access to the PBX interface via Firewall/WAF. <br>2. **Disable Service**: If not critical, disable the `Asterisk-Cli` or web interface. <br>3.β¦
β‘ **Urgency**: **HIGH**. <br>π¨ **Priority**: Immediate action required. <br>π **Risk**: Public exploits + Auth requirement makes it a prime target for targeted attacks on communication infrastructure.
