A vulnerability in Azure Function Apps allowed extraction of Managed Identity credentials from the encrypted startup context of Linux containers. This gave attackers with container access the ability to persist as the Managed Identity, breaking the intended security model. Microsoft has since patched the issue by encrypting the sensitive payload.
Azure CLI commands were found to leak sensitive information, including credentials, through GitHub Actions logs. The vulnerability affects multiple Azure CLI commands and could expose secrets in public and private repositories. Microsoft has issued updates to Azure CLI, Azure Pipelines, and GitHub Actions to address the issue.
Palo Alto discovered that Azure CLI commands were found to leak sensitive credentials and environment variables in GitHub Actions logs. This issue affects both public and private repositories, potentially exposing secrets to unauthorized parties. The problem stems from the Azure CLI's design to echo back accessed/created/updated/deleted resource information, which can include sensitive data. Later research by Orca Security revealed that AWS CLI and Google Cloud CLI were affected by the same iss…
Huntress has analyzed the emerging SysAid CVE-2023-47246 vulnerability and recreated the attack chain with a proof-of-concept exploit.
Huntress has uncovered a series of unauthorized access, revealing a threat actor using ScreenConnect to infiltrate multiple healthcare organizations.
Take a deep dive into the operations of one of the most active players in the Ransomware-as-a-Service market.
SafeBreach Labs researchers developed methods to leverage Microsoft Azure's Automation Service for free, undetectable cryptocurrency mining. They found three ways to execute miners: two using their own environment and Azure's resources for free, and one in a victim's environment undetected. The techniques could potentially be used for any task requiring code execution on Azure.
CVE-2023-22518 is being exploited in Confluence for Cerber ransomware deployment. Read up on Huntress’ observations and mitigation guidance.
AppFlow had an undocumented service called sandstoneconfigurationservicelambda. An undocumented field (awsOwnedManagedAppCredentialsArn) could be used during connector registration and connector updates. Specifying a victim's Secret ARN as that field disclosed the clientId and clientSecret, so long as the victim Secret ARN belonged to a connection profile which is of the type OAuth or contains clientId and clientSecret.
The AppFlow WooCommerce connector allowed specification of a full URL. The connector included details of response content when the URL offered an unexpected response. This means you could make arbitrary GET requests to any URL from the WooCommerce connector, and view the response content. The response in the error was truncated to 500 characters.
A vulnerability in Google Bard allowed for prompt injection and data exfiltration through its Extensions feature. By injecting malicious instructions into shared Google Docs, an attacker could force Bard to render images with exfiltrated chat history data in the URL. The exploit bypassed Content Security Policy using Google Apps Script.
Amazon Managed Workflows for Apache Airflow (MWAA) and the Task instance details page in the Google Composer UI were not patched against CVE-2023-29247 (Stored XSS). This meant that post-authentication, a threat actor could have exploited this to store their JavaScript payload in the victim's managed Apache Airflow instance and run JavaScript on behalf of the victim (who could be an admin or another user with higher permissions than the threat actor, thereby leading to privilege escalation). Wi…
CVE-2023-46604 is a critical remote code execution vulnerability in Apache ActiveMQ. Patch now to avoid any potential adversary exploitation.

In Azure AI Playground, a Prompt Injection attack could cause an LLM to return markdown tags. This would have allowed an adversary whose data makes it into the chat context (e.g., via an uploaded file) to achieve exfiltration of the victim’s data by rendering hyperlinks. However, the severity of this issue is low, as there were no integrations that could pull remote content. This means Indirect Prompt Injection was not possible, and it would require the victim to copy the malicious prompt from …
In Vertex AI Studio, a Prompt Injection attack could cause the LLM to return markdown tags. This could have allowed an adversary whose data makes it into the chat context (e.g., via an uploaded file) to achieve exfiltration of the victim’s data by rendering hyperlinks. However, the severity of this issue is low, as there were no integrations that could pull remote content. This means Indirect Prompt Injection was not possible, and it would require the victim to copy the malicious prompt from el…

AWS identified an issue in the Amazon WorkSpaces Windows client which resulted in unintentionally logging connection debugging information to a user's local system. This data could include usernames or passwords if they contain specific characters: \ (backslash) or " (double quotes). If an attacker gained access to an Amazon WorkSpaces user's machine, they could then compromise such credentials from the log.
