A vulnerability in the web-based management interface 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 full 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 a CVSS score of 8.1, this vulnerability is classified as high severity, indicating significant risk to organizations that deploy this software. Attackers may leverage this vulnerability to execute unauthorized SQL commands, potentially leading to data breaches and integrity issues. Organizations should prioritize patching immediately.
The urgency for defenders is underscored by the potential impact on confidentiality and integrity, as a successful attack can lead to exposure of sensitive information. Currently, there are no public exploits available, and the status of this vulnerability is awaiting further analysis.
Organizations utilizing Cisco Secure FMC Software should be vigilant and monitor their systems for any signs of exploitation. The risk to organizations includes unauthorized access to databases and the possibility of data manipulation.
Vulnerability Details
The vulnerability is classified under CWE-89, which pertains to SQL injection vulnerabilities. It affects the web-based management interface of the Cisco Secure FMC Software, as described in the official advisory. The flaw arises from insufficient input validation, allowing attackers to manipulate SQL queries. The vulnerability was published on March 4, 2026, and is currently classified as awaiting analysis.
Technical Analysis
The root cause of this vulnerability is inadequate validation of user input in the web management interface, leading to potential SQL injection attacks. The attack vector is network-based, indicating that an attacker can exploit this vulnerability remotely. The attack complexity is low, requiring minimal effort to execute an attack, and privileges required are low, as valid user credentials are necessary. No user interaction is required for exploitation, making this vulnerability particularly dangerous.
The confidentiality and integrity impacts are assessed as high, signifying that successful exploitation could lead to unauthorized access to sensitive data and possible alteration of that data. The availability impact is none, as the attack does not affect the availability of the system.
Risk & Impact Analysis
Organizations that deploy Cisco Secure FMC Software face real-world risks stemming from this vulnerability. The potential blast radius is significant, as the vulnerability permits remote SQL injection attacks, which can compromise databases and sensitive information. The urgency assessment is high due to the vulnerability's CVSS score of 8.1 and its potential for exploitation, even though it is not currently listed in the KEV catalog.
As organizations assess their risk posture, they should recognize that any delay in patching could expose them to serious security incidents. The possibility of data breaches emphasizes the importance of immediate action.
