The U.S. Department of Homeland Security Cybersecurity and Infrastructure Security Agency (CISA) has published a new alert in response to recently disclosed exploits that target F5 BIG-IP devices that are vulnerable to CVE-2020-5902. As the alert states, F5 Networks, Inc. (F5) released a patch for CVE-2020-5902 on June 30, 2020. Unpatched F5 BIG-IP devices are an attractive target for malicious actors. Affected organizations that have not applied the patch to fix this critical remote code execution (RCE) vulnerability risk an attacker exploiting CVE-2020-5902 to take control of their system. CISA notes it expects to see continued attacks exploiting unpatched F5 BIG-IP devices and strongly urges users and administrators to upgrade their software to the fixed versions. CISA also advises that administrators deploy the signature included in the alert to help them determine whether their systems have been compromised. The alert also provides additional detection measures and mitigations for victim organizations to help recover from attacks.
