Iodine | < 0.7.33 How the Exploit Works
The exploit takes advantage of a path traversal vulnerability in Iodine’s static file service. An attacker can craft malicious URLs to traverse directories and gain unauthorized access to files outside the public folder. Because the service does not properly sanitize input, these URLs can potentially lead to sensitive system information or data leakage.
Conceptual Example Code
Here is a conceptual example of how an attacker might exploit the vulnerability using a malicious URL:
GET /../../../etc/passwd HTTP/1.1
Host: vulnerable-iodine.example.comIn this example, the attacker is attempting to access the /etc/passwd file, which is typically restricted and contains sensitive user information.
Mitigation Guidance
To mitigate the risks posed by this vulnerability, it is recommended to apply the vendor’s patch to update Iodine to version 0.7.33 or later. In situations where immediate patching is not feasible, implementing Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as temporary mitigation by blocking or alerting on suspicious URL patterns.
