How the Exploit Works
The vulnerability arises from improper storage of sensitive information in cleartext. An attacker with network access could exploit this flaw by intercepting the data as it is being transmitted or by accessing the resource where the information is stored. The vulnerability does not require any user interaction and requires only low-level privileges, making it easy for an attacker to exploit.
Conceptual Example Code
This is a conceptual example of how an attacker might exploit this vulnerability, by making a network request to access the resource where the sensitive data is stored:
GET /resource/containing/sensitive/data HTTP/1.1
Host: target.example.comUpon receiving the response, the attacker could easily read the sensitive data, as it is stored in cleartext.
Mitigation Guidance
Users of affected versions of Emerson ValveLink products are advised to apply the vendor patch immediately to mitigate this vulnerability. In cases where immediate patching is not possible, the use of a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide temporary mitigation. However, these are not long-term solutions and can only minimize the risk of exploitation. The only definitive solution is to apply the patch provided by the vendor.
