Exploitability
| CWE ID | Description |
|---|---|
| CWE-89 | The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data. |
Attack-Flow Graph
AI Powered Q&A
Can you explain this vulnerability to me?
This vulnerability exists in the REST API of Cisco Secure FMC Software and allows an authenticated remote attacker to perform SQL injection attacks.
It occurs because the software does not properly validate user-supplied input.
An attacker with valid user credentials in certain roles can send specially crafted requests to exploit this flaw.
Successful exploitation could let the attacker read the database contents and access certain files on the underlying operating system.
- Valid roles required include Administrator, Security approver, Intrusion admin, Access admin, or Network admin.
How can this vulnerability impact me? :
If exploited, this vulnerability could allow an attacker to gain unauthorized read access to sensitive database information.
The attacker could also read certain files on the underlying operating system, potentially exposing confidential data.
This could lead to information disclosure and compromise of system confidentiality.
How does this vulnerability affect compliance with common standards and regulations (like GDPR, HIPAA)?:
I don't know
How can this vulnerability be detected on my network or system? Can you suggest some commands?
I don't know
What immediate steps should I take to mitigate this vulnerability?
To mitigate this vulnerability, ensure that only trusted users with valid credentials and appropriate roles (Administrator, Security approver, Intrusion admin, Access admin, Network admin) have access to the Cisco Secure FMC Software REST API.
Additionally, monitor and restrict access to the REST API to reduce the risk of exploitation by authenticated attackers.
Applying any available patches or updates from Cisco for the Secure FMC Software is also recommended once they are released.
