Networking equipment maker Cisco Systems has rolled out patches to address three critical security vulnerabilities in its IOS XE network operating system that remote attackers could potentially abuse to execute arbitrary code with administrative privileges and trigger a denial-of-service (DoS) condition on vulnerable devices. The list of three flaws is as follows - CVE-2021-34770  (CVSS score: 10.0) - Cisco IOS XE Software for Catalyst 9000 Family Wireless Controllers CAPWAP Remote Code Execution Vulnerability CVE-2021-34727  (CVSS score: 9.8) - Cisco IOS XE SD-WAN Software Buffer Overflow Vulnerability CVE-2021-1619  (CVSS score: 9.8) - Cisco IOS XE Software NETCONF and RESTCONF Authentication Bypass Vulnerability The most severe of the issues is CVE-2021-34770, which Cisco calls a "logic error" that occurs during the processing of  CAPWAP  (Control And Provisioning of Wireless Access Points) packets that enable a central wireless Controller to manage a...

Apple on Thursday released security updates to fix multiple security vulnerabilities in older versions of  iOS  and  macOS  that it says have been detected in exploits in the wild, in addition to expanding patches for a previously plugged security weakness abused by NSO Group's Pegasus surveillance tool to target iPhone users. Chief among them is CVE-2021-30869, a type confusion flaw that resides in the kernel component  XNU  developed by Apple that could cause a malicious application to execute arbitrary code with the highest privileges. The Cupertino-based tech giant said it addressed the bug with improved state handling. Google's Threat Analysis Group, which is credited with reporting the flaw, said it detected the vulnerability being "used in conjunction with a N-day remote code execution targeting WebKit." Two other flaws include  CVE-2021-30858 and CVE-2021-30860 , both of which were resolved by the company earlier this month following disc...

An unpatched design flaw in the implementation of Microsoft Exchange's Autodiscover protocol has resulted in the leak of approximately 100,000 login names and passwords for Windows domains worldwide. "This is a severe security issue, since if an attacker can control such domains or has the ability to 'sniff' traffic in the same network, they can capture domain credentials in plain text (HTTP basic authentication) that are being transferred over the wire," Guardicore's Amit Serper  said  in a technical report. "Moreover, if the attacker has DNS-poisoning capabilities on a large scale (such as a nation-state attacker), they could systematically syphon out leaky passwords through a large-scale DNS poisoning campaign based on these Autodiscover TLDs [top-level domains]." The Exchange  Autodiscover  service enables users to configure applications such as Microsoft Outlook with minimal user input, allowing just a combination of email addresses and pas...

Security researchers have disclosed an unpatched weakness in Microsoft Windows Platform Binary Table (WPBT) affecting all Windows-based devices since Windows 8 that could be potentially exploited to install a rootkit and compromise the integrity of devices. "These flaws make every Windows system vulnerable to easily-crafted attacks that install fraudulent vendor-specific tables," researchers from Eclypsium  said  in a report published on Monday. "These tables can be exploited by attackers with direct physical access, with remote access, or through manufacturer supply chains. More importantly, these motherboard-level flaws can obviate initiatives like  Secured-core  because of the ubiquitous usage of  ACPI  [Advanced Configuration and Power Interface] and WPBT." WPBT, introduced with Windows 8 in 2012, is a  feature  that enables "boot firmware to provide Windows with a platform binary that the operating system can execute."  In other wor...

Sysadmins know what the risks are of running unpatched services. Given the choice, and unlimited resources, most hardworking administrators will ensure that all systems and services are patched consistently. But things are rarely that simple. Technical resources are limited, and patching can often be more complicated than it appears at first glance. Worse, some services are so hidden in the background, that they just don't make it onto the list of things to be patched. QEMU is one of those services that tend to create difficulties with patching. It works away in the background and is easy to take for granted. Plus, patching QEMU involves significant technical and practical challenges – while requiring enormous resources. In this article, we'll address some of the difficulties around patching QEMU, and point to a solution that takes the toughest bits out of QEMU patching. Ignoring QEMU patching is a big risk You'll probably know about it if you're using QEMU – shor...

An "insidious" new SMS smishing malware has been found targeting Android mobile users in the U.S. and Canada as part of an ongoing campaign that uses SMS text message lures related to COVID-19 regulations and vaccine information in an attempt to steal personal and financial data. Proofpoint's messaging security subsidiary Cloudmark coined the emerging malware "TangleBot." "The malware has been given the moniker TangleBot because of its many levels of obfuscation and control over a myriad of entangled device functions, including contacts, SMS and phone capabilities, call logs, internet access, and camera and microphone," the researchers  said . Besides capabilities to obtain sensitive information, the malware is engineered to control device interaction with banking or financial apps using overlay screens and plunder account credentials from financial activities initiated on the phones. The attacks themselves originate from SMS messages that claim ...

More than one terabyte of data containing 5.5 million files has been left exposed, leaking personal information of over 100,000 customers of a Colombian real estate firm, according to cybersecurity company WizCase. The breach was discovered by Ata Hakçıl and his team in a database owned by Coninsa Ramon H, a company that specializes in architecture, engineering, construction, and real estate services. "There was no need for a password or login credentials to see this information, and the data was not encrypted," the researchers  said  in an exclusive report shared with The Hacker News. The data exposure is the result of a misconfigured Amazon Web Services (AWS) Simple Storage Service (S3) bucket, causing sensitive information such as clients' names, photos, and addresses to be disclosed. The details stored in the bucket range from invoices and income documents to quotes and account statements dating between 2014 and 2021. The complete list of information contained in...
