A critical vulnerability in GitLab's GitHub import feature allows remote code execution. The issue stems from improper handling of Sawyer::Resource objects, enabling injection of Redis commands. This can be escalated to execute arbitrary bash commands on the SaaS managed service as well as self-hosted GitLab servers, potentially leading to full system compromise.
We unravel an investigation that details one way threat actors are able to gather cleartext passwords via NPPSPY.
The @actions/core package had a delimiter injection vulnerability in the exportVariable function. Attackers could use a known delimiter to break out of a specific variable and assign values to other arbitrary variables. This may have allowed modification of path or environment variables without the intention of workflow or action authors.

In GCP's case, they introduced a modification to the Cloud SQL's PostgreSQL engine allowing the role assigned to the tenant (cloudsqlsuperuser) to arbitrarily change the ownership of a table to any user or role in the database. Thus, an attacker could (1) create a new table, (2) create an index function with a malicious payload, and (3) change the table owner to GCP’s superuser role (cloudsqladmin). Next, by initiating an ANALYZE command, the malicious function is executed with GCP’s superuser …
A vulnerability was discovered in Cloud Shell that enabled command injection and remote shell access. By manipulating the "project" parameter, an attacker could have cause an unencoded Python script execution flaw. Exploiting this flaw, they could inject a command to display the contents of the "/etc/passwd" file, successfully execute arbitrary commands and obtain remote shell access. However, the impact of this is unclear, as an attacker would seemingly only be able to gain such a remote shell…

We founded Huntress with a commitment to elevating the cybersecurity community as a guiding principle. Here are some of the ways we strive to make a difference.
How we almost got rich
We’re currently monitoring a situation that entails a hacker selling access to an MSP with access to 50+ customers, totaling 1,000+ servers.
A digital forensics investigation can be tedious. Fortunately, there are some efficient ways that you can still achieve success as an investigator.
What Group-IB’s new all-in-one solution offers: cybersecurity management, network event analysis, and lightning-fast stops to attacks
This blog is a follow-up on our How to Crush Cybercriminals with Managed Antivirus webinar. We'll dive deeper through a threat analysis lens.
If a malicious actor with prior access to an AWS environment has permission to modify the S3 Replication Service role access policy, they could abuse cross-account replication to exfiltrate stolen data to an external bucket under their control. Moreover, when configured to replicate to multiple buckets at once, and if logging is only scoped to specific buckets (as opposed to being set to log "all current and future buckets"), then the S3 Replication Service only logs a putObject event to CloudT…

A critical security flaw in Google Cloud Platform's Cloud Workstations allows unauthorized access and privilege escalation. The vulnerability stems from persistent session management, enabling users to access and exploit credentials of higher-privileged users. This can lead to impersonation, creation of new service accounts with elevated permissions, and bypassing of access controls.
AWS CodeArtifact was susceptible to dependency confusion / substitution (i.e, publication of a malicious package to a public repository with the same name as an organization’s internal package). AWS fixed this issue by adding package origin controls, allowing users to limit how versions of a given package can be added to a CodeArtifact repository.
The Microsoft Azure Site Recovery suite contained a DLL hijacking flaw that allowed for privilege escalation from any low privileged user to SYSTEM on hosts where this service was installed. Incorrect permissions on the cxprocessserver service's executable directory allowed new files to be created in it by any user. Since the service ran automatically and with SYSTEM privileges and attempted to load DLLs from the directory, this allowed for a DLL hijacking / planting attack.

Amazon Elastic Kubernetes Service (EKS) uses IAM to provide authentication to the cluster through the AWS IAM Authenticator for Kubernetes (aws-iam-authenticator). aws-iam-authenticator can be installed on any Kubernetes cluster, and it is installed by default in any EKS cluster both on AWS cloud and on-premises (Amazon EKS Anywhere). A security issue was discovered in aws-iam-authenticator where an allow-listed IAM identity may be able to modify their username and escalate privileges. The bug …

Group-IB’s platform allows organizations to overcome cyber risks
A vulnerability in Service Fabric allows Linux containers to escalate their privileges in order to gain root privileges on the node, and then compromise all of the nodes in the cluster. An attacker would need to have read/write access to the cluster, and the vulnerability could be exploited on containers that are configured to have runtime access, but this is granted by default to every container. Though the bug exists in both the Windows and Linux versions, it is only exploitable on Linux.
