Cisco has published an advisory of a critical vulnerability found in Cisco’s Secure FMC Software. According to security expert Brandon Sakai of Cisco, he found the vulnerability while conducting normal internal security tests. This vulnerability was rated with a CVSS score of 10.0 (the maximum possible). This high score emphasizes the severity of its danger and expected impact among all projects.
Even though this vulnerability was issued earlier this year and carries a CVSS score of 10, many organizations are still vulnerable to this critical exploit. This vulnerability affects the following when you configure Cisco Secure FMC Software for RADIUS authentication. This especially applies to web-based management interfaces and SSH management. Such a bad configuration puts an entire system in jeopardy, as attackers can use this leak to obtain sensitive information they should not have access to.
Details of the Vulnerability
The vulnerability in question is specifically how the Cisco Secure FMC Software handles sending RADIUS authenticity checks to various devices. When properly configured, these systems have been developed to complement and further security efforts. The new flaw still opens doors to terrible exploitation.
Cisco, meanwhile, has warned customers of the present threat. Organizations that rely on RADIUS for their operational security should be particularly skittish. As technology continues to embed into the core of business operations, the impact of these kinds of vulnerabilities starts to hit home.
“For this vulnerability to be exploited, Cisco Secure FMC Software must be configured for RADIUS authentication for the web-based management interface, SSH management, or both.” – Cisco
Recommended Actions for Users
Given this finding, Cisco recommends that all customers using the Secure FMC Software check their configurations as soon as possible. Organizations need to verify if their systems use RADIUS authentication for system management interfaces and remediate accordingly if they are.
In order to address these risks, we strongly recommend users take further precautions to secure their accounts and personally identifiable information. This could mean ensuring their software is always upgraded to the latest version and tracking when anyone has tried to access it without authorization.

Ongoing Security Measures
Cisco remains committed to delivering secure products and services. The disclosure of this vulnerability serves as an important reminder that continuous internal security assessments and proactive measures must be taken to protect sensitive information from exposure.
As companies continue to maneuver through a more and more convoluted digital space, the necessity for hyper-aware security solutions is a constant priority. Ongoing engagement between enterprises, suppliers like Cisco, and the wider security community remains critical in understanding and reducing security vulnerabilities before they can be exploited.
