Red Hat Security Advisory 2023-1200-01 - The gnutls packages provide the GNU Transport Layer Security library, which implements cryptographic algorithms and protocols such as SSL, TLS, and DTLS.

Cybersecurity researchers have discovered the first-ever illicit cryptocurrency mining campaign used to mint Dero since the start of February 2023. "The novel Dero cryptojacking operation concentrates on locating Kubernetes clusters with anonymous access enabled on a Kubernetes API and listening on non-standard ports accessible from the internet," CrowdStrike said in a new report shared with The

Organizations will likely have until the end of 2024 to gain visibility and control over their keys and certificates.

### Summary A vulnerability was identified in Nomad and Nomad Enterprise (“Nomad”) such that a user with the submit-job ACL capability can submit a job that can escalate to management-level privileges. This vulnerability, CVE-2023-1299, was introduced in Nomad 1.5.0 and fixed in Nomad 1.5.1. ### Background Nomad 1.4.0 introduced the concept of workload identity so that tasks can access variables without needing to access them through Nomad HTTP API with an ACL token. In 1.5.0, the identity block was introduced, which exposes the workload identity token to the workload so it can access Nomad HTTP API via a unix domain socket without configuring mTLS. ### Details During internal testing, we discovered it was possible to abuse the workload identity to elevate to management-level privilege if the workload identity did not have any attached ACL policies. ### Remediation Customers should evaluate the risk associated with this issue and consider upgrading to Nomad 1.5.1 or newer. See Noma...

A new Golang-based malware dubbed GoBruteforcer has been found targeting web servers running phpMyAdmin, MySQL, FTP, and Postgres to corral the devices into a botnet. "GoBruteforcer chose a Classless Inter-Domain Routing (CIDR) block for scanning the network during the attack, and it targeted all IP addresses within that CIDR range," Palo Alto Networks Unit 42 researchers said. "The threat actor

Government entities and large organizations have been targeted by an unknown threat actor by exploiting a security flaw in Fortinet FortiOS software to result in data loss and OS and file corruption. "The complexity of the exploit suggests an advanced actor and that it is highly targeted at governmental or government-related targets," Fortinet researchers Guillaume Lovet and Alex Kong said in an

SAP NetWeaver Application Server Java for Classload Service - version 7.50, does not perform any authentication checks for functionalities that require user identity, resulting in escalation of privileges. This failure has a low impact on confidentiality of the data such that an unassigned user can read non-sensitive server data.

The National Institute of Standards and Technology (NIST) is one of the standard-bearers in global cybersecurity. The U.S.-based institute’s cybersecurity framework helps organizations of all sizes understand, manage, and reduce their cyber-risk levels and better protect their data. Its importance in the fight against cyberattacks can’t be overstated. While NIST hasn’t directly developed
