CISA Adds 10 New Known Actively Exploited Vulnerabilities to its Catalog

Aug 29, 2022
The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Friday added 10 new actively exploited vulnerabilities to its  Known Exploited Vulnerabilities (KEV) Catalog , including a high-severity security flaw affecting industrial automation software from Delta Electronics. The issue, tracked as  CVE-2021-38406  (CVSS score: 7.8), impacts DOPSoft 2 versions 2.00.07 and prior. A successful exploitation of the flaw may lead to arbitrary code execution. "Delta Electronics DOPSoft 2 lacks proper validation of user-supplied data when parsing specific project files (improper input validation) resulting in an out-of-bounds write that allows for code execution," CISA said in an alert. It's worth noting that CVE-2021-38406 was originally disclosed as part of an industrial control systems (ICS) advisory  published  in September 2021. However, there are no patches that address the vulnerability, with CISA noting that the "impacted product is end-of-life and shoul

Apple Releases Patch for New Actively Exploited iOS and iPadOS Zero-Day Vulnerability

Oct 25, 2022
Tech giant Apple on Monday rolled out updates to remediate a zero-day flaw in iOS and iPadOS that it said has been actively exploited in the wild. The weakness, given the identifier CVE-2022-42827 , has been described as an out-of-bounds write issue in the Kernel, which could be abused by a rogue application to execute arbitrary code with the highest privileges. Successful exploitation of out-of-bounds write flaws, which typically occur when a program attempts to write data to a memory location that's outside of the bounds of what it is allowed to access, can result in corruption of data, a crash, or execution of unauthorized code. The iPhone maker said it addressed the bug with improved bounds checking, while crediting an anonymous researcher for reporting the vulnerability. As is usually the case with actively exploited zero-day flaws, Apple refrained from sharing more specifics about the shortcoming other than acknowledging that it's "aware of a report that this i

Microsoft pushes Emergency Patch for Zero-Day Internet Explorer Flaw

Aug 19, 2015
It's time to immediately patch your Internet Explorer – Once again! Microsoft has issued an emergency out-of-band patch for all supported versions of Internet Explorer browser, to fix a critical security flaw that hackers are actively exploiting to hijack control of targeted computers. The Zero-Day flaw (assigned CVE-2015-2502 ) is a Remote Code Execution vulnerability that could be exploited when a user visits a booby-trapped website or open a malicious email on an affected machine. The security bug actually resides in the way Internet Explorer handles objects in memory. If successfully exploited, a hacker could gain the same user privileges as the current user. Therefore, users running administrator accounts on their machines as well as systems where IE is frequently used, like workstations or terminal servers, are particularly at the most risk from this vulnerability.

Microsoft Patches 5 Zero-Day Vulnerabilities Being Exploited in the Wild

Oct 12, 2016
Microsoft has released its monthly Patch Tuesday update including a total of 10 security bulletin, and you are required to apply the whole package of patches altogether, whether you like it or not. That's because the company is kicking off a controversial new all-or-nothing patch model this month by packaging all security updates into a single payload, removing your ability to pick and choose which individual patches to install. October's patch bundle includes fixes for at least 5 separate dangerous zero-day vulnerabilities in Internet Explorer, Edge, Windows and Office products that attackers were already exploiting in the wild before the patch release. The patches for these zero-day flaws are included in MS16-118, MS16-119, MS16-120, MS16-121 and MS16-126. All the zero-days are being exploited in the wild, allowing attackers to execute a remote command on victim's system. Although none of the zero-day flaws were publicly disclosed prior to Tuesday, the company wa

Microsoft Says Russian Hackers Using Unpatched Windows Bug Disclosed by Google

Nov 02, 2016
Google's Threat Analysis Group publically disclosed on Monday a critical zero-day vulnerability in most versions of Windows just 10 days after privately disclosed both zero days to Microsoft and Adobe. While Adobe rushed an emergency patch for its Flash Player software on October 26, Microsoft had yet to release a fix. Microsoft criticized Google's move, saying that the public disclosure of the vulnerability — which is being exploited in the wild — before the company had time to prepare a fix, puts Windows users at "potential risk." The result? Windows Vista through current versions of Windows 10 is still vulnerable , and now everybody knows about the critical vulnerability. Now, Microsoft said that the company would be releasing a patch for the zero-day flaw on 8th November, as part of its regular round of monthly security updates. Russian Hackers are actively exploiting critical Windows kernel bug Microsoft acknowledged the vulnerability in a blog
