According to CISA and other reports, an old vulnerability in Cisco ASA and FTD, CVE-2020-3259, is being exploited by the Akira Ransomware group (and others). This vulnerability involves an unauthenticated memory disclosure issue.IONIX research team has conducted a scan for CVE-2020-3580, another Cisco ASA/FTD vulnerability. With high probability, assets that are vulnerable to CVE-2020-3580 are also vulnerable to CVE-2020-3259.While the IONIX research team tests the feasibility of simulating a CVE-2020-3259 exploit non-intrusively, we recommend:1. Use the IONIX platform to test whether you are vulnerable to spot assets that are vulnerable to CVE-2020-3580 (Action Items). 2. Review all the Cisco ASA assets. Notice that assets might be vulnerable to CVE-2020-3259 without being vulnerable to CVE-2020-3580.3. For relevant assets, follow the guide by Cisco.4. Keep an eye on security bulletins and updates from IONIX and Cisco

How IONIX’s External Exposure Management Platform Detects and Validates
Zero-Days to Shrink MTTR1
Map your entire attack surface (continously)
IONIX uses multi-factor discovery methods, including DNS analysis, certificate mapping, metadata inspection, and more, to automatically map every internet-facing asset across your environment. This includes cloud instances, third-party platforms, shadow IT, and even forgotten infrastructure that traditional tools miss.
2
Monitor for new CVEs
Dozens of threat intel feeds using agentic technology are continuously analyzed to detect the appearance of proof-of-concept code, exploit kits, and indicators of active targeting. IONIX goes further by applying AI to proactively evaluate whether emerging vulnerabilities are likely to be exploited, even before PoCs go public.
3
Identify Potential External Exposures
Not all CVEs matter. IONIX filters vulnerabilities by asking attacker-centric questions: Can it be reached from the internet? Does it require authentication? Is it being exploited in the wild? This dramatically reduces noise and focuses teams on threats that can actually be weaponized.
4
Create Safe, Scalable Exploit Validations
IONIX transforms real-world PoCs into safe, non-intrusive test payloads that can be run in production environments without disruption. These simulations are precisely targeted to the systems that are vulnerable, ensuring rapid validation without unnecessary load.
5
Execute Exploit Validations
By combining context about software stack, versioning, exposure status, and reachability, IONIX ensures that only the right payloads are executed against the right assets, maximizing efficiency and minimizing risk.
6
Drive Fast and Actionable Remediation
Results are routed through integrations with ticketing, SOAR, and SIEM tools. Issues are written in plain language, bundled into remediation clusters, and prioritized based on asset criticality, exploitability, and blast radius. This shortens mean time to remediation (MTTR) and empowers teams to act with confidence.
