POEditor | Up to 0.9.10
How the Exploit Works
The vulnerability lies in the improper handling of CSRF tokens by POEditor, allowing an attacker to trick a victim into performing an action without their knowledge or consent. Moreover, it allows for Path Traversal, letting an attacker access, read, or modify files on the server that they should not have access to.
Conceptual Example Code
Here is a brief conceptual example of how the vulnerability might be exploited via an HTTP request:
POST /poeditor/path HTTP/1.1
Host: target.example.com
Content-Type: application/json
{
"path": "../../../../../../../etc/passwd"
}
In the above conceptual example, the attacker is attempting to traverse the file system to access the ‘/etc/passwd’ file, which could potentially contain sensitive information.
Mitigation
To mitigate this vulnerability, it is recommended to apply the patch provided by the vendor. If the patch cannot be applied immediately, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as a temporary mitigation strategy.
