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.

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.

TOP VULNERABILITY THIS WEEK: Microsoft Patch Tuesday includes update to crucial cryptography features
=========================================================
NOTABLE RECENT SECURITY ISSUES
SELECTED BY THE TALOS SECURITY INTELLIGENCE AND RESEARCH GROUP

Title: Microsoft cryptography vulnerability lingers after Patch Tuesday
Description: The U.S. National Security Agency released a warning late last week, urging users to update their Microsoft products as soon as possible to fix a vulnerability in its cryptographic certificate-signing function. Attackers could use this bug to sign a program, and make it appear as if it is from a trusted source, without the user ever knowing about the adversary’s actions. A security researcher was even able to create a proof of concept “Rick Rolling” the NSA’s website to display a popular internet meme. The NSA’s statement says that it believes “the vulnerability to be severe and that sophisticated cyber actors will understand the underlying flaw very quickly and, if exploited, would render the previously mentioned platforms as fundamentally vulnerable.”

Title: Emotet continues to grow, spike in spam to start off 2020
Description: Emotet continues to infect individuals and organizations all over the world, but Cisco Talos recently discovered a new relationship between Emotet and the .mil (U.S. military) and .gov (U.S./state government) top-level domains (TLDs). When Emotet emerged from its summer vacation back in mid-September 2019, relatively few outbound emails were seen directed at the .mil and .gov TLDs. But sometime in the past few months, Emotet was able to successfully compromise one or more persons working for or with the U.S. government. As a result of this, Talos saw a rapid increase in the number of infectious Emotet messages directed at the .mil and .gov TLDs in December 2019.
