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
