![Salt Bugs Allow Full RCE as Root on Cloud Servers](/static/build/img/news/salt-bugs-allow-full-rce-as-root-on-cloud-servers.jpg)
The open-source Salt management framework contains high-severity security vulnerabilities that allow full remote code execution as root on servers in data centers and cloud environments. "The ClearFuncs class also exposes the method prep auth info(), which returns the root key used to authenticate commands from the local root user on the master server. This root key can then be used to remotely call administrative commands on the master server. This unintentional exposure provides a remote un-authenticated attacker with root-equivalent access to the salt master."

That's according to researchers at Radware, who also said that it's notable how quickly Hoaxcalls operators have moved to weaponize the ZyXel bug, which as of this time of writing, has still not been addressed in a ZyXel advisory. According to the Palo Alto Unit 42 researchers who found it, the original sample featured three DDoS attack vectors: UDP, DNS and HEX floods; and, it was seen infecting devices through two vulnerabilities: A DrayTek Vigor2960 remote code-execution vulnerability and a GrandStream Unified Communications remote SQL injection bug.
![Update MS Office, Paint 3D to plug RCE vulnerabilities](/static/build/img/news/alt/microsoft-office-stats-small.jpg)
A week after the April 2020 Patch Tuesday, Microsoft has released out-of-band security updates for its Office suite, to fix a handful of vulnerabilities that attackers could exploit to achieve remote code execution. At the same time, a security update has also been released for Paint 3D, the company's free app for creating 3D models, because the source of the fixed vulnerabilities is something that both Office and Paint 3D have in common: the Autodesk FBX library.
![RCE Exploit Released for IBM Data Risk Manager](/static/build/img/news/rce-exploit-released-for-ibm-data-risk-manager.png)
UPDATED. Four serious security vulnerabilities in the IBM Data Risk Manager have been identified that can lead to unauthenticated remote code execution as root in vulnerable versions, according to analysis - and a proof-of-concept exploit is available. IBM weighed in on the problem this week, after a researcher went public with the bugs, one of which may end up being a zero-day issue - Big Blue is still investigating.
![Cisco IP Phone Harbors Critical RCE Flaw](/static/build/img/news/cisco-ip-phone-harbors-critical-rce-flaw.jpg)
Cisco is warning of a critical flaw in the web server of its IP phones. Cisco issued patches in a Wednesday advisory for the flaw, which affects various versions of its Cisco IP phones for small- to medium-sized businesses.
![Update Firefox again – more RCEs and an Android “takeover” bug too](/static/build/img/news/update-firefox-again-more-rces-and-an-android-takeover-bug-too.png)
We'll refer to this one a Fourthytuesday instead, now that Firefox has reduced its update wavelength to four weeks to get important-but-not-zero-day-critical fixes out just that bit more frequently. If your automatic update hasn't happened yet, a manual check will let you "Jump the queue" and get the update a bit sooner.
![Google Patches Critical RCE Vulnerabilities in Android's System Component](/static/build/img/news/alt/cyberattack-costs-scaled-small.jpg)
Google this week released the April 2020 set of security patches for the Android operating system to address over 50 vulnerabilities, including four critical issues in the System component. "The most severe of these issues is a critical security vulnerability in the System component that could enable a remote attacker using a specially crafted file to execute arbitrary code within the context of a privileged process," Google notes in an advisory.
![Critical RCE Bug Affects Millions of OpenWrt-based Network Devices](/static/build/img/news/critical-rce-bug-affects-millions-of-openwrt-based-network-devices.jpg)
A cybersecurity researcher today disclosed technical details and proof-of-concept of a critical remote code execution vulnerability affecting OpenWrt, a widely used Linux-based operating system for routers, residential gateways, and other embedded devices that route network traffic. Tracked as CVE-2020-7982, the vulnerability resides in the OPKG package manager of OpenWrt that exists in the way it performs integrity checking of downloaded packages using the SHA-256 checksums embedded in the signed repository index.
![Windows users under attack via two new RCE zero-days](/static/build/img/news/alt/data-breach-stats-small.jpg)
Attackers are exploiting two new zero-days in the Windows Adobe Type Manager Library to achieve remote code execution on targeted Windows systems, Microsoft warns. "There are multiple ways an attacker could exploit the vulnerability, such as convincing a user to open a specially crafted document or viewing it in the Windows Preview pane," the company shared, and said that the Outlook Preview Pane is not an attack vector for this vulnerability.
![Warning — Two Unpatched Critical 0-Day RCE Flaws Affect All Windows Versions](/static/build/img/news/warning-two-unpatched-critical-0-day-rce-flaws-affect-all-windows-versions.jpg)
Microsoft today issued a new security advisory warning billions of Windows users of two new critical, unpatched zero-day vulnerabilities that could let hackers remotely take complete control over targeted computers. According to Microsoft, both unpatched flaws are being used in limited, targeted attacks and impact all supported versions of the Windows operating system-including Windows 10, 8.1 and Server 2008, 2012, 2016, and 2019 editions, as well as Windows 7 for which Microsoft ended its support on January 14, 2020.
