Security researchers have discovered not one or two, but a total of seven security vulnerabilities in the popular open source Dnsmasq network services software, three of which could allow remote code execution on a vulnerable system and hijack it. Dnsmasq is a widely used lightweight network application tool designed to provide DNS (Domain Name System) forwarder, DHCP (Dynamic Host Configuration Protocol) server, router ads and network boot services for small networks. Dnsmasq comes pre-installed on various devices and operating systems, including Linux distributions such as Ubuntu and Debian, home routers, smartphones and Internet of Things (IoT) devices. A shodan scan for "Dnsmasq" reveals around 1.1 million instances worldwide. Recently, Google's security team reviewed Dnsmasq and discovered seven security issues, including DNS-related remote code execution, information disclosure, and denial-of-service (DoS) issues that can be triggered via DNS or DHCP. &q

You're probably familiar with the term "critical assets". These are the technology assets within your company's IT infrastructure that are essential to the functioning of your organization. If anything happens to these assets, such as application servers, databases, or privileged identities, the ramifications to your security posture can be severe.  But is every technology asset considered a critical asset? Moreover, is every technology asset considered a  business -critical asset? How much do we really know about the risks to our  business -critical assets?  Business-critical assets are the underlying technology assets of your business in general – and we all know that technology is just one of the 3 essential pillars needed for a successful business operation. In order to have complete cybersecurity governance, organizations should consider: 1) Technology, 2) Business processes, and 3) Key People. When these 3 pillars come together, organizations can begin to understand the

Facebook has paid out its largest Bug Bounty ever of $33,500 to a Brazilian security researcher for discovering and reporting a critical Remote code execution vulnerability, which potentially allows the full control of a server. In September, ' Reginaldo Silva' found an XML External Entity Expansion vulnerability affecting the part of Drupal that handled OpenID, which allows attacker to read any files on the webserver. As a feature, Facebook allows users to access their accounts using OpenID in which it receives an XML document from 3rd service and parse it to verify that it is indeed the correct provider or not i.e. Receives at https://www.facebook.com/openid/receiver.php  In November 2013, while testing Facebook's ' Forgot your password ' functionality, he found that the OpenID process could be manipulated to execute any command on the Facebook server remotely and also allows to read arbitrary files on the webserver. In a Proof-of-Concept ,

As much as you protect your electronics from being hacked, hackers are clever enough at finding new ways to get into your devices. But, you would hope that once a flaw discovered it would at least be fixed in few days or weeks, but that's not always the case. A three-year-old security vulnerability within a software component used by more than 6.1 Million smart devices still remains unpatched by many vendors, thereby placing Smart TVs, Routers, Smartphones, and other Internet of Things (IoT) products at risk of exploit. Security researchers at Trend Micro have brought the flaw to light that has been known since 2012 but has not been patched yet. Remote Code Execution Vulnerabilities  Researchers discovered a collection of Remote Code Execution (RCE) vulnerabilities in the Portable SDK for UPnP , or libupnp component – a software library used by mobile devices, routers, smart TVs, and other IoT devices to stream media files over a network. The flaws occur du

While Windows users are currently in fear of getting their systems hijacked by the WannaCry ransomware outbreak, Apple users are sitting relaxed, thinking that malware attacks are something that happens to Windows users, and not Apple. But you are mistaken – Apple products are also not immune to the hack attacks and malware infections, as an ebook can hack your Mac, iPhone, and iPad. Apple on Monday pushed out software updates for iOS, macOS, Safari, tvOS, iCloud, iTunes, and watchOS to fix a total of 67 unique security vulnerabilities, many of which allows attackers to perform remote code execution on an affected system. iOS is 10.3.2 for iPhone, iPad, and iPod Apple's mobile operating system iOS 10.3.2 for the iPhone, iPad and iPod touch addresses 41 security flaws, 23 of which resides in WebKit, including 17 remote code execution and 5 cross-site scripting (XSS) vulnerabilities. Besides this, iOS 10.3.2 also addresses a pair of flaws in iBooks for iOS (CVE-2017-24

As part of its "October Patch Tuesday," Microsoft has today released a large batch of security updates to patch a total of 62 vulnerabilities in its products, including a severe MS office zero-day flaw that has been exploited in the wild. Security updates also include patches for Microsoft Windows operating systems, Internet Explorer, Microsoft Edge, Skype, Microsoft Lync and Microsoft SharePoint Server. Besides the MS Office vulnerability, the company has also addressed two other publicly disclosed (but not yet targeted in the wild) vulnerabilities that affect the SharePoint Server and the Windows Subsystem for Linux. October patch Tuesday also fixes a critical Windows DNS vulnerability that could be exploited by a malicious DNS server to execute arbitrary code on the targeted system. Below you can find a brief technical explanation of all above mentioned critical and important vulnerabilities. Microsoft Office Memory Corruption Vulnerability (CVE-2017-11826) T

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has  added  three security flaws to its Known Exploited Vulnerabilities ( KEV ) catalog, citing evidence of active exploitation. The list of vulnerabilities is below - CVE-2022-35914  (CVSS score: 9.8) - Teclib GLPI Remote Code Execution Vulnerability CVE-2022-33891  (CVSS score: 8.8) - Apache Spark Command Injection Vulnerability CVE-2022-28810  (CVSS score: 6.8) - Zoho ManageEngine ADSelfService Plus Remote Code Execution Vulnerability The most critical of the three is  CVE-2022-35914 , which concerns a remote code execution vulnerability in the third-party library htmlawed present in  Teclib GLPI , an open source asset and IT management software package. The exact specifics surrounding the nature of attacks are unknown, but the Shadowserver Foundation in October 2022  noted  that it has seen exploitation attempts against its honeypots. Since then, a cURL-based one-line proof of concept (PoC) has been made a

For the last Patch Tuesday for this year, Microsoft has released 12 security bulletins, half of which are rated 'critical' as they give attackers remote code execution capabilities on the affected computers. The security bulletins address vulnerabilities in Microsoft's Windows, Office, Internet Explorer and Edge. The first critical security bulletin, MS16-144 , patches a total of 8 security vulnerabilities in Internet Explorer, 3 of which had publicly been disclosed before Microsoft issued patches for them, though the company said they're not being exploited in the wild. The 3 publicly disclosed vulnerabilities include a Microsoft browser information disclosure vulnerability (CVE-2016-7282), a Microsoft browser security feature bypass bug (CVE-2016-7281) and a scripting engine memory corruption vulnerability (CVE-2016-7202) that allow remote code execution on the affected computer. The remaining 5 security flaws include a scripting engine memory corruption b

Google has released the February Security Update for Android that patches multiple security vulnerabilities discovered in the latest version of Android operating system. In total, there were five "critical" security vulnerabilities fixed in the release along with four "high" severity and one merely "moderate" issues. Remote Code Execution Flaw in WiFi A set of two critical vulnerabilities has been found in the Broadcom WiFi driver that could be exploited by attackers to perform Remote Code Execution (RCE) on affected Android devices when connected to the same network as the attacker. The vulnerabilities (CVE-2016-0801 and CVE-2016-0802) can be exploited by sending specially crafted wireless control message packets that can corrupt kernel memory, potentially leading to remote code execution at the kernel level. "These vulnerabilities can be triggered when the attacker and the victim are associated with the same network," read

What's worse than knowing that innocent looking JPEGs, PDFs and font files can hijack your iPhone, iPad, and iPod. Yes, attackers can take over your vulnerable Apple's iOS device remotely – all they have to do is trick you to view a maliciously-crafted JPEG graphic or PDF file through a website or an email, which could allow them to execute malicious code on your system. That's a terrible flaw (CVE-2016-4673), but the good news is that Apple has released the latest version of its mobile operating system, iOS 10.1 , for iPhones and iPads to address this remote-code execution flaw, alongside an array of bug fixes. And now that the company has rolled out a security patch, some hackers would surely find vulnerable Apple devices to exploit the vulnerability and take full control of them. So, users running older versions of iOS are advised to update their mobile devices to iOS 10.1 as soon as possible. Besides this remote code execution flaw, the newest iOS 10.1 incl

The maintainers of the open-source continuous integration/continuous delivery and deployment (CI/CD) automation software Jenkins have resolved nine security flaws, including a critical bug that, if successfully exploited, could result in remote code execution (RCE). The issue, assigned the CVE identifier  CVE-2024-23897 , has been described as an arbitrary file read vulnerability through the built-in command line interface ( CLI ) "Jenkins uses the args4j library to parse command arguments and options on the Jenkins controller when processing CLI commands," the maintainers  said  in a Wednesday advisory. "This command parser has a feature that replaces an @ character followed by a file path in an argument with the file's contents (expandAtFiles). This feature is enabled by default and Jenkins 2.441 and earlier, LTS 2.426.2 and earlier does not disable it." A threat actor could exploit this quirk to read arbitrary files on the Jenkins controller file system
