@Risk: Security Alert
OUCH! Security Awareness
Case Leads DFIR Digest
Industrial Control Systems
Industrials & Infrastructure


@RISK provides a reliable weekly summary of (1) newly discovered attack vectors, (2) vulnerabilities with active new exploits, (3) insightful explanations of how recent attacks worked, and other valuable data

A key purpose of the @RISK is to provide the data that will ensure that the 20 Critical Controls (the US and UK benchmark for effective protection of networked systems) continue to be the most effective defenses for all known attack vectors. But since it is also valuable for security practitioners, SANS is making it available to the 145,000 security practitioners who have completed SANS security training and others at their organizations who hope to stay current with the offensive methods in use.

NOTABLE RECENT SECURITY ISSUES

SELECTED BY THE TALOS SECURITY INTELLIGENCE AND RESEARCH GROUP


Title: Cisco urging users to update Firepower Management Center immediately to fix severe bug

Description: Cisco disclosed a high-severity vulnerability in its Firepower Management Center last week that could allow an attacker to bypass the usual authentication steps. The vulnerability -- which was assigned a 9.8 severity score out of 10 -- exists in the way Firepower handles LDAP authentication responses from an external authentication server. An attacker could exploit this flaw by sending a specially crafted HTTP request to the device. Users are also encouraged to turn off LDAP configuration on their devices. Cisco also disclosed seven high-severity flaws and 19 medium-severity security issues in some of its other products, including Smart Software Manager.

Snort SIDs: 52627 - 52632, 52641 - 52646


Title: Exploitation of Citrix vulnerability spikes after POC released, patches followed

Description: Citrix rushed out a patch for its Application Delivery Controller (ADC) and Citrix Gateway products after proof of concept code leaked for a major vulnerability. The company first disclosed CVE-2019-19781 in December, saying a patch was forthcoming. But security researchers have noticed an uptick in exploitation attacks, forcing Citrix to move up its timeline.
