A vulnerability in the REST API of Cisco Secure FMC Software could allow an authenticated, remote attacker to conduct SQL injection attacks on an affected system. This vulnerability is due to inadequate validation of user-supplied input. An attacker could exploit this vulnerability by sending crafted requests to an affected device. A successful exploit could allow the attacker to obtain read access to the database and read certain files on the underlying operating system. To exploit this vulnerability, the attacker would need valid user credentials with any of the following roles: Administrator, Security approver, Access admin, or Network admin.
Given the CVSS score of 6.5, classified as medium severity, it is essential for organizations to understand the risk associated with this vulnerability. The potential data exposure can significantly impact the confidentiality of sensitive information stored within the database. The urgency for defenders is high, as attackers may leverage this vulnerability to gain unauthorized access.
Organizations should prioritize patching immediately.
As of the latest update, this vulnerability is still awaiting analysis, and no public exploits have been confirmed.
Mitigation steps should be implemented to prevent potential exploitation, including strict input validation and monitoring for unusual activity within the application.
Organizations should also consider implementing continuous security testing to identify and address vulnerabilities proactively.
Further details on this vulnerability can be found in the official advisory from Cisco.
Vulnerability Details
The vulnerability in question is classified under CWE-89, which pertains to SQL injection vulnerabilities. The attack vector is network-based, and the attack complexity is low, indicating that an attacker could exploit the vulnerability without requiring advanced skills.
The attack requires low privileges, as the attacker must possess valid user credentials.
Technical Analysis
The root cause of this vulnerability lies in the inadequate validation of user input within the REST API. Attackers could exploit this vulnerability by sending malicious SQL queries through crafted requests, which the server may execute without proper sanitization.
The attack vector is network-based, allowing remote attackers to exploit the vulnerability without physical access to the device. The attack complexity is low, and no user interaction is required to conduct the attack. The confidentiality impact is rated as high, indicating significant risk to sensitive data, while integrity and availability impacts are rated as none.
Risk & Impact Analysis
Risk to organizations includes potential unauthorized access to sensitive data stored in the database. The blast radius is considerable, as attackers may gain access to read critical system files, leading to further compromise.
Organizations should address this vulnerability in their priority patch cycle to mitigate risks associated with data exposure and ensure compliance with security best practices.
