Four different Microsoft Azure services have been found vulnerable to server-side request forgery ( SSRF ) attacks that could be exploited to gain unauthorized access to cloud resources. The security issues, which were discovered by Orca between October 8, 2022 and December 2, 2022 in Azure API Management, Azure Functions, Azure Machine Learning, and Azure Digital Twins, have since been addressed by Microsoft. "The discovered Azure SSRF vulnerabilities allowed an attacker to scan local ports, find new services, endpoints, and sensitive files - providing valuable information on possibly vulnerable servers and services to exploit for initial entry and the location of sensitive information to target," Orca researcher Lidor Ben Shitrit  said  in a report shared with The Hacker News. Two of the vulnerabilities affecting Azure Functions and Azure Digital Twins could be abused without requiring any authentication, enabling a threat actor to seize control of a server without eve...

A cybersecurity professional today demonstrated a long-known unpatched weakness in Microsoft's Azure cloud service by exploiting it to take control over Windows Live Tiles , one of the key features Microsoft built into Windows 8 operating system. Introduced in Windows 8, the Live tiles feature was designed to display content and notifications on the Start screen, allowing users to continuously pull up-to-date information from their favorite apps and websites. To make it easier for websites to offer their content as Live Tiles, Microsoft had a feature available on a subdomain of a separate domain, i.e., " notifications.buildmypinnedsite.com ," that allowed website admins to automatically convert their RSS feeds into a special XML format and use it as a meta tag on their websites. The service, which Microsoft had already shut down, was hosted on its own Azure Cloud platform with the subdomain configured/linked to an Azure account operated by the company. However,...

Microsoft has incorporated additional improvements to address the recently disclosed  SynLapse  security vulnerability in order to meet comprehensive  tenant isolation   requirements  in Azure Data Factory and Azure Synapse Pipelines. The latest safeguards include moving the shared integration runtimes to sandboxed ephemeral instances and using scoped tokens to prevent adversaries from using a client certificate to access other tenants' information. "This means that if an attacker could execute code on the  integration runtime , it is never shared between two different tenants, so no sensitive data is in danger," Orca Security said in a technical report detailing the flaw. In a statement shared with The Hacker News regarding the protections deployed, Microsoft said it fully mitigated different attack paths to the vulnerability across all integration runtime types. The tech giant stated that it "contained and closely monitored the backend certificate...

Cybersecurity researchers have discovered two security flaws in Microsoft's Azure Health Bot Service that, if exploited, could permit a malicious actor to achieve lateral movement within customer environments and access sensitive patient data. The critical issues, now patched by Microsoft, could have allowed access to cross-tenant resources within the service, Tenable said in a new report shared with The Hacker News. The Azure AI Health Bot Service is a cloud platform that enables developers in healthcare organizations to build and deploy AI-powered virtual health assistants and create copilots to manage administrative workloads and engage with their patients. This includes bots created by insurance service providers to allow customers to look up the status of a claim and ask questions about benefits and services, as well as bots managed by healthcare entities to help patients find appropriate care or look up nearby doctors. Tenable's research specifically focuses on on...

It's Patch Tuesday once again…time for another round of security updates for the Windows operating system and other Microsoft products. This month Windows users and system administrators need to immediately take care of a total of 63 security vulnerabilities, of which 12 are rated critical, 49 important and one moderate and one low in severity. Two of the vulnerabilities patched by the tech giant this month are listed as publicly known at the time of release, and one flaw is reported as being actively exploited in the wild by multiple cybercriminal groups. Zero-Day Vulnerability Being Exploited by Cyber Criminals The zero-day vulnerability, tracked as CVE-2018-8589 , which is being exploited in the wild by multiple advanced persistent threat groups was first spotted and reported by security researchers from Kaspersky Labs. The flaw resides in the Win32k component (win32k.sys), which if exploited successfully, could allow a malicious program to execute arbitrary code...

Businesses across the world have been hit by widespread disruptions to their Windows workstations stemming from a faulty update pushed out by cybersecurity company CrowdStrike. "CrowdStrike is actively working with customers impacted by a defect found in a single content update for Windows hosts," the company's CEO George Kurtz said in a statement . "Mac and Linux hosts are not impacted. This is not a security incident or cyber attack." The company, which acknowledged "reports of [ Blue Screens of Death ] on Windows hosts," further said it has identified the issue and a fix has been deployed for its Falcon Sensor product, urging customers to refer to the support portal for the latest updates. For systems that have been already impacted by the problem, the mitigation instructions are listed below - Boot Windows in Safe Mode or Windows Recovery Environment Navigate to the C:\Windows\System32\drivers\CrowdStrike directory Find the file named ...

Besides these, Microsoft has released patches for four critical RCE vulnerabilities in Windows built-in Remote Desktop Client application that could enabl...

CrowdStrike is alerting about an unfamiliar threat actor attempting to capitalize on the Falcon Sensor update fiasco to distribute dubious installers targeting German customers as part of a highly targeted campaign. The cybersecurity company said it identified what it described as an unattributed spear-phishing attempt on July 24, 2024, distributing an inauthentic CrowdStrike Crash Reporter installer via a website impersonating an unnamed German entity. The imposter website is said to have been created on July 20, a day after the botched update crashed nearly 9 million Windows devices, causing extensive IT disruptions across the world. "After the user clicks the Download button, the website leverages JavaScript (JS) that masquerades as JQuery v3.7.1 to download and deobfuscate the installer," CrowdStrike's Counter Adversary Operations team said . "The installer contains CrowdStrike branding, German localization, and a password [is] required to continue install...

Cybersecurity researchers have detailed a now-patched vulnerability in Google Cloud Platform (GCP) that could have enabled an attacker to elevate their privileges in the Cloud Composer workflow orchestration service that's based on Apache Airflow. "This vulnerability lets attackers with edit permissions in Cloud Composer to escalate their access to the default Cloud Build service account, which has high-level permissions across GCP services like Cloud Build itself, Cloud Storage, and Artifact Registry," Liv Matan, senior security researcher at Tenable, said in a report shared with The Hacker News. The shortcoming has been codenamed ConfusedComposer by the cybersecurity company, describing it as a variant of ConfusedFunction , a privilege escalation vulnerability impacting GCP's Cloud Functions service that an attacker could exploit to access other services and sensitive data in an unauthorized manner. The disclosure comes weeks after Tenable detailed another pr...

Cybersecurity researchers have uncovered three security weaknesses in Microsoft's Azure Data Factory Apache Airflow integration that, if successfully exploited, could have allowed an attacker to gain the ability to conduct various covert actions, including data exfiltration and malware deployment. "Exploiting these flaws could allow attackers to gain persistent access as shadow administrators over the entire Airflow Azure Kubernetes Service (AKS) cluster," Palo Alto Networks Unit 42 said in an analysis published earlier this month. The vulnerabilities, albeit classified as low severity by Microsoft, are listed below - Misconfigured Kubernetes RBAC in Airflow cluster Misconfigured secret handling of Azure's internal Geneva service, and Weak authentication for Geneva Besides obtaining unauthorized access, the attacker could take advantage of the flaws in the Geneva service to potentially tamper with log data or send fake logs to avoid raising suspicion when c...
