Cybersecurity researchers have disclosed a privilege escalation vulnerability impacting Google Cloud Platform's Cloud Functions service that an attacker could exploit to access other services and sensitive data in an unauthorized manner. Tenable has given the vulnerability the name ConfusedFunction. "An attacker could escalate their privileges to the Default Cloud Build Service Account and access numerous services such as Cloud Build, storage (including the source code of other functions), artifact registry and container registry," the exposure management company said in a statement. "This access allows for lateral movement and privilege escalation in a victim's project, to access unauthorized data and even update or delete it." Cloud Functions refers to a serverless execution environment that allows developers to create single-purpose functions that are triggered in response to specific Cloud events without the need to manage a server or update frame...

Docker is warning of a critical flaw impacting certain versions of Docker Engine that could allow an attacker to sidestep authorization plugins (AuthZ) under specific circumstances. Tracked as CVE-2024-41110 , the bypass and privilege escalation vulnerability carries a CVSS score of 10.0, indicating maximum severity. "An attacker could exploit a bypass using an API request with Content-Length set to 0, causing the Docker daemon to forward the request without the body to the AuthZ plugin, which might approve the request incorrectly," the Moby Project maintainers said in an advisory. Docker said the issue is a regression in that the issue was originally discovered in 2018 and addressed in Docker Engine v18.09.1 in January 2019, but never got carried over to subsequent versions (19.03 and later). The issue has been resolved in versions 23.0.14 and 27.1.0 as of July 23, 2024, after the problem was identified in April 2024. The following versions of Docker Engine are impacte...

The Internet Systems Consortium (ISC) has released patches to address multiple security vulnerabilities in the Berkeley Internet Name Domain ( BIND ) 9 Domain Name System (DNS) software suite that could be exploited to trigger a denial-of-service (DoS) condition. "A cyber threat actor could exploit one of these vulnerabilities to cause a denial-of-service condition," the U.S. Cybersecurity and Infrastructure Security Agency (CISA) said in an advisory. The list of four vulnerabilities is listed below - CVE-2024-4076 (CVSS score: 7.5) - Due to a logic error, lookups that triggered serving stale data and required lookups in local authoritative zone data could have resulted in an assertion failure CVE-2024-1975 (CVSS score: 7.5) - Validating DNS messages signed using the SIG(0) protocol could cause excessive CPU load, leading to a denial-of-service condition. CVE-2024-1737 (CVSS score: 7.5) - It is possible to craft excessively large numbers of resource record typ...

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...

Google said it's adding new security warnings when downloading potentially suspicious and malicious files via its Chrome web browser. "We have replaced our previous warning messages with more detailed ones that convey more nuance about the nature of the danger and can help users make more informed decisions," Jasika Bawa, Lily Chen, and Daniel Rubery from the Chrome Security team said . To that end, the search giant is introducing a two-tier download warning taxonomy based on verdicts provided by Google Safe Browsing: Suspicious files and Dangerous files. Each category comes with its own iconography, color, and text to distinguish them from one another and help users make an informed choice. Google is also adding what's called automatic deep scans for users who have opted-in to the Enhanced Protection mode of Safe Browsing in Chrome so that they don't have to be prompted each time to send the files to Safe Browsing for deep scanning before opening them. In...

Security questionnaires aren't just an inconvenience — they're a recurring problem for security and sales teams. They bleed time from organizations, filling the schedules of professionals with monotonous, automatable work. But what if there were a way to reduce or even altogether eliminate security questionnaires? The root problem isn't a lack of great questionnaire products — it's the questionnaires themselves. At SafeBase, we don't just talk about transparency — it's core to everything we do, from how we build our products to how we communicate about them. In the spirit of transparency, in this piece we're going to talk about our Trust Center platform at length:  Why we're believers in Trust Centers > security questionnaires How a Trust Center reduces and eliminates questionnaires How to demonstrate the ROI of investing in a Trust Center Let's dive in. Why a trust center first approach helps Solving the questionnaire problem means going beyond the questionnaire wit...

A zero-day security flaw in Telegram's mobile app for Android called EvilVideo made it possible for attackers to share malicious files disguised as harmless-looking videos. The exploit appeared for sale for an unknown price in an underground forum on June 6, 2024, ESET said. Following responsible disclosure on June 26, the issue was addressed by Telegram in version 10.14.5 released on July 11. "Attackers could share malicious Android payloads via Telegram channels, groups, and chat, and make them appear as multimedia files," security researcher Lukáš Štefanko said in a report. It's believed that the payload is concocted using Telegram's application programming interface ( API ), which allows for programmatic uploads of multimedia files to chats and channels. In doing so, it enables an attacker to camouflage a malicious APK file as a 30-second video.  Users who click on the video are displayed an actual warning message stating the video cannot be played and u...

There is one simple driver behind the modern explosion in SaaS adoption: productivity. We have reached an era where purpose-built tools exist for almost every aspect of modern business and it's incredibly easy (and tempting) for your workforce to adopt these tools without going through the formal IT approval and procurement process. But this trend has also increased the attack surface—and with it, the security and governance headaches that are still viewed as 100% the responsibility of IT and security teams. IT security leaders need scalable solutions for SaaS discovery and managing this ever-expanding attack surface. At the same time, their finance counterparts are seeking to cut technology spend (rather than salaries or headcount)—especially the low-hanging fruit of underutilized or over-deployed SaaS licenses, which Gartner estimates to be about  25% of all SaaS subscriptions . But, the key question is - where can you reduce your SaaS attack surface (and spend) without impa...

The threat actor known as Patchwork has been linked to a cyber attack targeting entities with ties to Bhutan to deliver the Brute Ratel C4 framework and an updated version of a backdoor called PGoShell. The development marks the first time the adversary has been observed using the red teaming software, the Knownsec 404 Team said in an analysis published last week. The activity cluster, also called APT-C-09, Dropping Elephant, Operation Hangover, Quilted Tiger, and Zinc Emerson, is a state-sponsored actor likely of Indian origin. Known for conducting spear-phishing and watering hole attacks against China and Pakistan, the hacking crew is believed to be active since at least 2009, according to data shared by Chinese cybersecurity firm QiAnXin. Last July, Knownsec 404 disclosed details of an espionage campaign aimed at universities and research organizations in China that leveraged a .NET-based implant codenamed EyeShell to fetch and execute commands from an attacker-controlled ...

Cybersecurity firm CrowdStrike on Wednesday blamed an issue in its validation system for causing millions of Windows devices to crash as part of a widespread outage late last week. "On Friday, July 19, 2024 at 04:09 UTC, as part of regular operations, CrowdStrike released a content configuration update for the Windows sensor to gather telemetry on possible novel threat techniques," the company said in its Preliminary Post Incident Review (PIR). "These updates are a regular part of the dynamic protection mechanisms of the Falcon platform. The problematic Rapid Response Content configuration update resulted in a Windows system crash." The incident impacted Windows hosts running sensor version 7.11 and above that was online between July 19, 2024, 04:09 UTC and 05:27 UTC and received the update. Apple macOS and Linux systems were not affected. CrowdStrike said it delivers security content configuration updates in two ways, one via Sensor Content that's shippe...
