How the Exploit Works
The exploit takes advantage of the improper preservation of permissions in Salesforce OmniStudio’s FlexCards. An attacker can manipulate this flaw to gain unauthorized access to Custom Settings data. The flawed security mechanism fails to properly preserve permissions, making it possible for low-level users to access sensitive data they are not supposed to reach.
Conceptual Example Code
A conceptual example of how the vulnerability might be exploited might involve a specially crafted HTTP request like the following:
GET /api/v1/settings/custom HTTP/1.1
Host: vulnerable-omnistudio-instance.salesforce.com
Authorization: Bearer low_privilege_tokenIn this example, the attacker uses a low-privilege token to request custom settings data that should normally be inaccessible. The server, failing to properly enforce access controls due to the vulnerability, returns the sensitive data.
Mitigation Guidance
Salesforce has released a patch for this vulnerability, and users are strongly encouraged to update their OmniStudio to the latest version to prevent exploitation. As a temporary mitigation, users could employ a Web Application Firewall (WAF) or Intrusion Detection System (IDS) to monitor and block suspicious activity. However, these methods are not foolproof and updating the software is the most reliable solution.
