Internet Explorer Exploit | Breaking Cybersecurity News | The Hacker News

Microsoft today issued an out-of-band security update to patch a critical zero-day vulnerability in Internet Explorer (IE) Web browser that attackers are already exploiting in the wild to hack into Windows computers. Discovered by security researcher Clement Lecigne of Google's Threat Analysis Group, the vulnerability, tracked as CVE-2018-8653, is a remote code execution (RCE) flaw in the IE browser's scripting engine. According to the advisory, an unspecified memory corruption vulnerability resides in the scripting engine JScript component of Microsoft Internet Explorer that handles execution of scripting languages. If exploited successfully, the vulnerability could allow attackers to execute arbitrary code in the context of the current user. "If the current user is logged on with administrative user rights, an attacker who successfully exploited the vulnerability could take control of an affected system. An attacker could then install programs; view, change, ...

A serious vulnerability has been discovered in all the latest versions of Microsoft's Internet Explorer that allows malicious hackers to inject malicious code into users' websites and steal cookies, session and login credentials. UNIVERSAL XSS BUG WITH SAME ORIGIN POLICY BYPASS The vulnerability is known as a Universal Cross Site Scripting (XSS) flaw. It allows attackers to bypass the Same-Origin Policy, a fundamental browser security mechanism, in order to launch highly credible phishing attacks or hijack users' accounts on any website. The Same Origin Policy is one of the guiding principles that seek to protect users' browsing experience. SOP actually prevents one site from accessing or modifying the browser properties, such as cookies, location, response etc, by any other site, ensuring that no third-party can inject code without the authorization of the owner of the website. DEMONSTRATION Recently, a proof-of-concept exploit published by a group, known as Deusen, sho...

If you invite guest users into your Entra ID tenant, you may be opening yourself up to a surprising risk.  A gap in access control in Microsoft Entra's subscription handling is allowing guest users to create and transfer subscriptions into the tenant they are invited into, while maintaining full ownership of them.  All the guest user needs are the permissions to create subscriptions in their home tenant, and an invitation as a guest user into an external tenant. Once inside, the guest user can create subscriptions in their home tenant, transfer them into the external tenant, and retain full ownership rights. This stealthy privilege escalation tactic allows a guest user to gain a privileged foothold in an environment where they should only have limited access. Many organizations treat guest accounts as low-risk based on their temporary, limited access, but this behavior, which works as designed, opens the door to known attack paths and lateral movement within the resource t...
