No affected components available
A flaw in how restforce constructs URLs may allow an attacker to inject additional parameters into Salesforce API requests.
Impact
This flaw is only exploitable in applications that pass user input directly to restforce's select, find, describe, update, upsert, and destroy methods.
Vulnerable code might look like:
client.select('SomeSalesForceObject', params[:some-id],
...)
In such an application, attackers could pass 0016000000MRatd/describe as a request parameter, causing the server to make a request to a different endpoint than the server is designed to handle. Since the Salesforce REST API supports overriding HTTP methods via a request parameter, an attacker could also cause the client's select() method to modify data, by passing 0016000000MRatd/?_HttpMethod=PATCH&other-query-params=....
Workarounds
If possible, applications should track salesforce IDs internally, rather than passing user-supplied IDs to salesforce. Such practice mitigates this vulnerability, and in general is desirable for ensuring strong access control.
The vulnerability can be exploited over the network without needing physical access. It is easy for an attacker to exploit this vulnerability. An attacker does not need any special privileges or access rights. No user interaction is needed for the attacker to exploit this vulnerability. The impact is confined to the system where the vulnerability exists. There is a high impact on the confidentiality of the information. There is a high impact on the integrity of the data. There is a high impact on the availability of the system.
Active exploitation in the wild has been confirmed. Immediate patching or mitigation is required.
The exploit probability is very low. The vulnerability is unlikely to be exploited in the next 30 days.
We did not find any exploit available. Neither in GitHub repositories nor in the Exploit-Database.
