Product Releases Should Not Be Scary

Product Releases Should Not Be Scary
November 25, 2021The Hacker News
Every Product Manager and Software Developer should know that pushing feature updates to production via traditional channels is as archaic as painting on cave walls. The smart are always quick to adapt to new, innovative technologies, and this mindset is exactly what makes normal companies great. The landscape is changing fast, especially in IT . Change isn't just necessary, but more often than not, it's the single-most-important variable that determines a company's chances of survival.  The fact of the matter is that NOT using Feature Flags leads to a more cumbersome, expensive, and slower type of rollout. Simply put, it makes your project less competitive with those that have their deployments better organized, and that's  an edge that you can't afford to lose . Feature Flags are changing how things work Many companies are using Feature Flags these days, and for good measure.  It's safer and allows for more granular control over what you're building.

Watch Out! Zyxel Firewalls and VPNs Under Active Cyberattack

Watch Out! Zyxel Firewalls and VPNs Under Active Cyberattack
June 25, 2021Ravie Lakshmanan
Taiwanese networking equipment company Zyxel is warning customers of an ongoing attack targeting a "small subset" of its security products such as firewall and VPN servers. Attributing the attacks to a "sophisticated threat actor," the firm noted that the attacks single out appliances that have remote management or SSL VPN enabled, namely in the USG/ZyWALL, USG FLEX, ATP, and VPN series running on-premise ZLD firmware, implying that the targeted devices are publicly accessible over the internet. "The threat actor attempts to access a device through WAN; if successful, they then bypass authentication and establish SSL VPN tunnels with unknown user accounts, such as 'zyxel_slIvpn', 'zyxel_ts', or 'zyxel_vpn_test', to manipulate the device's configuration," Zyxel said in an  email message , which was shared on Twitter. As of writing, it's not immediately known if the attacks are exploiting previously known vulnerabilities

June 17, 2021Ravie Lakshmanan
Google has rolled out yet another update to Chrome browser for Windows, Mac, and Linux to fix four security vulnerabilities, including one zero-day flaw that's being exploited in the wild. Tracked as  CVE-2021-30554 , the high severity flaw concerns a  use after free vulnerability  in WebGL (aka Web Graphics Library), a JavaScript API for rendering interactive 2D and 3D graphics within the browser. Successful exploitation of the flaw could mean corruption of valid data, leading to a crash, and even execution of unauthorized code or commands. The issue was reported to Google anonymously on June 15, Chrome technical program manager Srinivas Sista  noted , adding the company is "aware that an exploit for CVE-2021-30554 exists in the wild." While it's usually the norm to limit details of the vulnerability until a majority of users are updated with the fix, the development comes less than 10 days after Google addressed another zero-day vulnerability exploited in act

Critical RCE Vulnerability Found in VMware vCenter Server — Patch Now!
May 25, 2021Ravie Lakshmanan
VMware has rolled out patches to address a critical security vulnerability in vCenter Server that could be leveraged by an adversary to execute arbitrary code on the server. Tracked as CVE-2021-21985 (CVSS score 9.8), the issue stems from a lack of input validation in the Virtual SAN ( vSAN ) Health Check plug-in, which is enabled by default in the vCenter Server. "A malicious actor with network access to port 443 may exploit this issue to execute commands with unrestricted privileges on the underlying operating system that hosts vCenter Server," VMware  said  in its advisory. VMware vCenter Server is a server management utility that's used to control virtual machines, ESXi hosts, and other dependent components from a single centralized location. The flaw affects vCenter Server versions 6.5, 6.7, and 7.0 and Cloud Foundation versions 3.x and 4.x. VMware credited Ricter Z of 360 Noah Lab for reporting the vulnerability.

Update Your Chrome Browser to Patch 2 New In-the-Wild 0-Day Exploits
April 13, 2021Ravie Lakshmanan
Google on Tuesday released a new version of Chrome web-browsing software for Windows, Mac, and Linux with patches for two newly discovered security vulnerabilities for both of which it says exploits exist in the wild, allowing attackers to engage in active exploitation. One of the two flaws concerns an insufficient validation of untrusted input in its V8 JavaScript rendering engine (CVE-2021-21220), which was demonstrated by Dataflow Security's Bruno Keith and Niklas Baumstark at the  Pwn2Own 2021  hacking contest last week. While Google moved to fix the flaw quickly, security researcher Rajvardhan Agarwal published a  working exploit  over the weekend by reverse-engineering the patch that the Chromium team pushed to the open-source component, a factor that may have played a crucial role in the release. UPDATE:   Agarwal, in an email to The Hacker News, confirmed that there's one more vulnerability affecting Chromium-based browsers that has been patched in the latest vers

NSA Discovers New Vulnerabilities Affecting Microsoft Exchange Servers
April 13, 2021Ravie Lakshmanan
In its April slate of patches, Microsoft rolled out fixes for a total of  114 security flaws , including an actively exploited zero-day and four remote code execution bugs in Exchange Server. Of the  114 flaws , 19 are rated as Critical, 88 are rated Important, and one is rated Moderate in severity. Chief among them is  CVE-2021-28310 , a privilege escalation vulnerability in Win32k that's said to be under active exploitation, allowing attackers to elevate privileges by running malicious code on a target system.  Cybersecurity firm Kaspersky, which discovered and reported the flaw to Microsoft in February, linked the zero-day exploit to a threat actor named Bitter APT, which was found exploiting a similar flaw ( CVE-2021-1732 ) in attacks late last year. "It is an escalation of privilege (EoP) exploit that is likely used together with other browser exploits to escape sandboxes or get system privileges for further access," Kaspersky researcher Boris Larin  said .

Apple May Start Delivering Security Patches Separately From Other OS Updates

Apple May Start Delivering Security Patches Separately From Other OS Updates
March 17, 2021Ravie Lakshmanan
Apple may be changing the way it delivers security patches to its devices running iOS and iPadOS mobile operating systems. According to code spotted in iOS 14.5, the iPhone maker is reportedly working on a method for delivering security fixes independently of other OS updates. The changes were first reported by  the 9to5Mac  website. While Google's Android has had monthly security patches rolled out that are completely divorced from the OS-related updates, iOS has traditionally bundled security updates along with an upgrade to the latest version of the OS. For instance, Apple rolled out iOS 14.4.1 earlier this month just to address one security vulnerability in WebKit that could have allowed adversaries to run arbitrary code on devices via malicious web content. But with this new setting called "Install Security Updates" added to the software update menu, it's expected that Apple will let users choose between either installing the entire iOS update or just the

Researcher Discloses Critical RCE Flaws In Cisco Security Manager
November 16, 2020Ravie Lakshmanan
Cisco has published multiple security advisories concerning critical flaws in Cisco Security Manager (CSM) a week after the networking equipment maker quietly released patches with version 4.22 of the platform. The development comes after Code White researcher Florian Hauser (frycos) yesterday publicly disclosed proof-of-concept ( PoC ) code for as many as 12 security vulnerabilities affecting the  web interface of CSM  that makes it possible for an unauthenticated attacker to achieve remote code execution (RCE) attacks. The flaws were responsibly reported to Cisco's Product Security Incident Response Team (PSIRT) three months ago, on July 13. "Since Cisco PSIRT became unresponsive and the published release 4.22 still doesn't mention any of the vulnerabilities,"  claimed frycos  in a tweet, citing the reasons for going public with the PoCs yesterday. Cisco Security Manager  is an end-to-end enterprise solution that allows organizations to enforce access policies

November 11, 2020Ravie Lakshmanan
Google has patched two more zero-day flaws in the Chrome web browser for desktop, making it the fourth and fifth actively exploited vulnerabilities addressed by the search giant in recent weeks. The company released  86.0.4240.198  for Windows, Mac, and Linux, which it said will be rolling out over the coming days/weeks to all users. Tracked as CVE-2020-16013 and CVE-2020-16017, the flaws were discovered and reported to Google by "anonymous" sources, unlike previous cases, which were uncovered by the company's Project Zero elite security team. Google acknowledged that exploits for both the vulnerabilities exist in the wild but stopped short of sharing more specifics to allow a majority of users to install the fixes. According to the release notes, the two flaws are: CVE-2020-16013:  An "inappropriate implementation" of its V8 JavaScript rendering engine was reported on November 9. CVE-2020-16017:  An  use-after-free  memory corruption issue in Chrome
