A new Linux security vulnerability dubbed Looney Tunables has been discovered in the GNU C library's ld.so dynamic loader that, if successfully exploited, could lead to a local privilege escalation and allow a threat actor to gain root privileges. Tracked as  CVE-2023-4911  (CVSS score: 7.8), the issue is a buffer overflow that resides in the dynamic loader's processing of the  GLIBC_TUNABLES environment variable . Cybersecurity firm Qualys, which  disclosed  details of the bug, said it was introduced as a code commit made in April 2021. The GNU C library, also called  glibc , is a core library in Linux-based systems that offers foundational features such as open, read, write, malloc, printf, getaddrinfo, dlopen, pthread_create, crypt, login, and exit. glibc's  dynamic loader  is a crucial component that's responsible for preparing and running programs, including finding the necessarily shared object dependencies required as well as loading them into memory and lin

CVE-2022-22071  (CVSS score: 8.4), described as a use-after-free in Automotive OS Platform, was originally patched by the company as part of its May 2022 updates. While additional specifics about the remaining three flaws are expected to be made

Cybersecurity researchers have disclosed multiple critical security flaws in the  TorchServe tool  for serving and scaling PyTorch models that could be chained to achieve remote code execution on affected systems. Israel-based runtime application security company Oligo, which made the discovery, has coined the vulnerabilities  ShellTorch . "These vulnerabilities [...] can lead to a full chain Remote Code Execution (RCE), leaving countless thousands of services and end-users — including some of the world's largest companies — open to unauthorized access and insertion of malicious AI models, and potentially a full server takeover," security researchers Idan Levcovich, Guy Kaplan, and Gal Elbaz  said . The list of flaws, which have been addressed in  version 0.8.2 , is as follows - No CVE - Unauthenticated Management Interface API Misconfiguration (0.0.0.0) CVE-2023-43654  (CVSS score: 7.2) - A remote server-side request forgery ( SSRF ) that leads to remote code exe

Nearly three dozen counterfeit packages have been discovered in the npm package repository that are designed to exfiltrate sensitive data from developer systems, according to findings from Fortinet FortiGuard Labs. One set of packages – named @expue/webpack, @expue/core, @expue/vue3-renderer, @fixedwidthtable/fixedwidthtable, and @virtualsearchtable/virtualsearchtable – harbored an obfuscated JavaScript file that's capable of gathering valuable secrets. This includes Kubernetes configurations, SSH keys, and system metadata such as username, IP address, and hostname. The cybersecurity firm said it also discovered another collection of four modules, i.e., binarium-crm, career-service-client-0.1.6, hh-dep-monitoring, and orbitplate, which results in the unauthorized extraction of source code and configuration files. "The targeted files and directories may contain highly valuable intellectual property and sensitive information, such as various application and service credent

APIs, also known as application programming interfaces, serve as the backbone of modern software applications, enabling seamless communication and data exchange between different systems and platforms. They provide developers with an interface to interact with external services, allowing them to integrate various functionalities into their own applications. However, this increased reliance on APIs has also made them attractive targets for cybercriminals. In recent years, the rise of API breaches has become a growing concern in the world of cybersecurity. One of the main reasons behind the rise of API breaches is inadequate security measures implemented by developers and organizations. Many APIs are not properly secured, leaving them vulnerable to attacks. Moreover, hackers have developed sophisticated techniques that specifically target weaknesses within APIs. For example, they may leverage malicious code injections into requests or manipulate responses from an API endpoint to gain

Security Configuration Assessment (SCA)  is critical to an organization's cybersecurity strategy. SCA aims to discover vulnerabilities and misconfigurations that malicious actors exploit to gain unauthorized access to systems and data. Regular  security configuration assessments  are essential in maintaining a secure and compliant environment, as this minimizes the risk of cyber attacks. The assessment provides insight into your current security posture by performing configuration baseline checks on services and applications running on critical systems. How SCA works  SCA is performed by checking the configurations of your IT assets against known benchmarks such as the Center for Internet Security (CIS) benchmark and compliance standards such as NIST, GDPR, and HIPPA. Regulatory standards provide a global benchmark for best practices to help organizations enhance their IT hygiene and improve customer trust. The CIS benchmark provides a guideline for best practices for security c

Firewall and distributed denial-of-service (DDoS) attack prevention mechanisms in Cloudflare can be circumvented by exploiting gaps in cross-tenant security controls, defeating the very purpose of these safeguards, it has emerged. "Attackers can utilize their own Cloudflare accounts to abuse the per-design trust-relationship between Cloudflare and the customers' websites, rendering the protection mechanism ineffective," Certitude researcher Stefan Proksch  said  in a report published last week. The problem, per the Austrian consulting firm, is the result of shared infrastructure available to all tenants within Cloudflare, regardless of whether they are legitimate or otherwise, thereby making it easy for malicious actors to abuse the implicit trust associated with service and defeat the guardrails. The first issue stems from opting for a shared Cloudflare certificate to authenticate HTTP(S) requests between the service's reverse proxies and the customer's origi
