Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: OS Command Injection in D-Link DIR820LA1. π₯ **Consequences**: Attackers inject malicious payloads via the `ping_addr` parameter. This leads to **privilege escalation to ROOT**.β¦
π‘οΈ **Root Cause**: Improper neutralization of special elements used in an OS command. π **Flaw**: The `ping.ccp` module fails to sanitize the `ping_addr` input.β¦
π¦ **Affected Product**: D-Link DIR820LA1 Router. π **Vendor**: D-Link (China). π **Specific Version**: **FW105B03**. Only this specific firmware build is confirmed vulnerable.
Q4What can hackers do? (Privileges/Data)
π **Privileges**: Escalates to **ROOT** (highest level). π **Data Access**: Full control over the router. Hackers can execute arbitrary OS commands, steal network traffic, or pivot to internal networks.
Q5Is exploitation threshold high? (Auth/Config)
π **Auth/Config**: The vulnerability exists in the `ping.ccp` interface.β¦
π₯ **Public Exp?**: YES. π **PoC Available**: Nuclei templates exist on GitHub (ProjectDiscovery). π **Wild Exploitation**: High risk. Automated scanners can detect and exploit this easily.
Q7How to self-check? (Features/Scanning)
π **Self-Check**: Scan for D-Link DIR820LA1 running **FW105B03**. Use Nuclei templates targeting CVE-2023-25280. Check if the `ping_addr` parameter in `ping.ccp` is vulnerable to command injection payloads.
