The U.S. Cybersecurity and Infrastructure Security Agency issued an alert on Friday to warn organizations about the risk posed by a recently patched vulnerability affecting F5 Networks' BIG-IP application delivery controller.

The critical security hole, identified as CVE-2020-5902, allows an attacker with access to the product's Traffic Management User Interface configuration utility to obtain credentials and other sensitive data, intercept traffic, and execute arbitrary code or commands, resulting in the system getting completely compromised.

CISA says government departments and agencies have been seeing scanning and reconnaissance activity associated with this flaw since July 6.

The agency has been investigating several potential breaches resulting from the exploitation of this vulnerability, including against U.S. government and commercial organizations, and it has so far confirmed two instances where systems have been compromised.

The agency's recommendations in case of a breach include reimaging compromised hosts, resetting account passwords, limiting access to the vulnerable management interface, and implementing network segmentation to prevent the attacker from moving laterally within the network.
