Q1What is this vulnerability? (Essence + Consequences)
๐จ **Essence**: Roxy-WI has a critical **Remote Code Execution (RCE)** vulnerability. ๐ **Consequences**: Attackers can execute arbitrary system commands on the server, leading to total server compromise and data theft.
Q2Root Cause? (CWE/Flaw)
๐ก๏ธ **Root Cause**: **CWE-74** (OS Command Injection). The flaw lies in `/app/options.py`. The `subprocess_execute` function fails to sanitize user inputs, allowing malicious commands to slip through. ๐ฅ
Q3Who is affected? (Versions/Components)
๐ฅ **Affected**: **Roxy-WI** versions **before 6.1.1.0**. ๐ฆ This includes the web interface used to manage Haproxy, Nginx, and Keepalived servers. โ ๏ธ
Q4What can hackers do? (Privileges/Data)
๐ **Attacker Capabilities**: Unauthenticated hackers can run **system commands** with the privileges of the Roxy-WI process. ๐ This allows full control over the underlying OS, data exfiltration, and lateral movement.
Q5Is exploitation threshold high? (Auth/Config)
๐ **Exploitation Threshold**: **LOW**. ๐ No authentication (PR:N) is required. The attack vector is Network (AV:N) with Low Complexity (AC:L). Any remote user can trigger this. ๐ฏ
Q6Is there a public Exp? (PoC/Wild Exploitation)
๐ **Public Exploit**: **YES**. โ A Nuclei template is available on GitHub (projectdiscovery/nuclei-templates). Wild exploitation is highly likely given the ease of access. ๐
Q7How to self-check? (Features/Scanning)
๐ **Self-Check**: Scan for Roxy-WI instances. Use tools like **Nuclei** with the specific CVE-2022-31126 template. ๐งช Check if the version is < 6.1.1.0. Look for the `/app/options.py` endpoint. ๐ต๏ธโโ๏ธ
Q8Is it fixed officially? (Patch/Mitigation)
๐ฉน **Official Fix**: **YES**. ๐ ๏ธ The vendor released a patch. Upgrade to **Roxy-WI version 6.1.1.0** or later to resolve the injection flaw in the options handling. ๐ฅ
Q9What if no patch? (Workaround)
๐ง **No Patch Workaround**: If you cannot upgrade immediately, **block external access** to the Roxy-WI web interface via firewall rules. ๐งฑ Restrict access to trusted IPs only.โฆ
๐ฅ **Urgency**: **CRITICAL**. ๐จ CVSS Score indicates High Impact (C:H, I:H). Since it requires **no authentication**, immediate patching or isolation is mandatory to prevent immediate compromise. โณ
