How the Exploit Works
The vulnerability emerges when a user logs in via the SAP Business One native client. Upon login, the SLD backend service fails to enforce the proper encryption of certain APIs. This failure leads to the exposure of sensitive credentials within the http response body, which an attacker can capture and exploit for unauthorized access to resources, data leakage, or system compromise.
Conceptual Example Code
Here’s a conceptual example of the exploit, represented as an HTTP request:
POST /login HTTP/1.1
Host: vulnerable-SAP-Client.com
Content-Type: application/json
{ "username": "user", "password": "pass" }
HTTP/1.1 200 OK
Content-Type: application/json
{ "username": "user", "password": "pass", "api_key": "exposed_api_key" }In the example above, when a user logs in, the system responds with the user’s credentials and API key in plaintext. An attacker can use a network intercept tool to capture and exploit these credentials.
Remediation and Mitigation
The most effective solution to this vulnerability is the application of the vendor-supplied patch. Businesses using SAP Business One should apply this patch as soon as possible. If immediate patching is not possible, a temporary mitigation measure could be the use of a Web Application Firewall (WAF) or Intrusion Detection System (IDS). These can help detect and block attempts to exploit this vulnerability. However, these are not long-term solutions and cannot substitute the need for patching and updating the system.
