GitLab has released security updates to address two critical vulnerabilities, including one that could be exploited to take over accounts without requiring any user interaction. Tracked as  CVE-2023-7028 , the flaw has been awarded the maximum severity of 10.0 on the CVSS scoring system and could facilitate account takeover by sending password reset emails to an unverified email address. The DevSecOps platform said the vulnerability is the result of a bug in the email verification process, which allowed users to reset their password through a secondary email address. It affects all self-managed instances of GitLab Community Edition (CE) and Enterprise Edition (EE) using the below versions - 16.1 prior to 16.1.6 16.2 prior to 16.2.9 16.3 prior to 16.3.7 16.4 prior to 16.4.5 16.5 prior to 16.5.6 16.6 prior to 16.6.4 16.7 prior to 16.7.2 GitLab said it addressed the issue in GitLab versions 16.5.6, 16.6.4, and 16.7.2, in addition to backporting the fix to versions 16.1....

Cybersecurity researchers have identified a new attack that exploits misconfigurations in Apache Hadoop and Flink to deploy cryptocurrency miners within targeted environments. "This attack is particularly intriguing due to the attacker's use of packers and rootkits to conceal the malware," Aqua security researchers Nitzan Yaakov and Assaf Morag  said  in an analysis published earlier this week. "The malware deletes contents of specific directories and modifies system configurations to evade detection." The infection chain targeting Hadoop leverages a misconfiguration in the YARN's (Yet Another Resource Negotiator)  ResourceManager , which is responsible for tracking resources in a cluster and scheduling applications. Specifically, the misconfiguration can be exploited by an unauthenticated, remote threat actor to execute arbitrary code by means of a crafted HTTP request, subject to the privileges of the user on the node where the code is executed. The ...

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has  added  a critical security vulnerability impacting Microsoft SharePoint Server to its Known Exploited Vulnerabilities ( KEV ) catalog, citing evidence of active exploitation. The issue, tracked as  CVE-2023-29357  (CVSS score: 9.8), is a privilege escalation flaw that could be exploited by an attacker to gain administrator privileges. Microsoft  released patches  for the bug as part of its June 2023 Patch Tuesday updates. “An attacker who has gained access to spoofed JWT authentication tokens can use them to execute a network attack which bypasses authentication and allows them to gain access to the privileges of an authenticated user,” Redmond said. “The attacker needs no privileges nor does the user need to perform any action.” Security researcher Nguyễn Tiến Giang (Jang) of StarLabs SG  demonstrated an exploit  for the flaw at the Pwn2Own Vancouver hacking contest last ye...

The ubiquity of GitHub in information technology (IT) environments has made it a lucrative choice for threat actors to host and deliver malicious payloads and act as  dead drop resolvers , command-and-control, and data exfiltration points. “Using GitHub services for malicious infrastructure allows adversaries to blend in with legitimate network traffic, often bypassing traditional security defenses and making upstream infrastructure tracking and actor attribution more difficult,” Recorded Future  said  in a report shared with The Hacker News. The cybersecurity firm described the approach as “living-off-trusted-sites” (LOTS), a spin on the living-off-the-land (LotL) techniques often adopted by threat actors to conceal rogue activity and fly under the radar. Prominent among the methods by which GitHub is  abused   relates  to  payload   delivery , with some actors leveraging its features for command-and-control (C2) obfuscation. Last month, Reve...

Cybersecurity researchers have  developed  a proof-of-concept (PoC) code that exploits a  recently disclosed critical flaw  in the Apache OfBiz open-source Enterprise Resource Planning (ERP) system to execute a memory-resident payload. The vulnerability in question is  CVE-2023-51467  (CVSS score: 9.8), a bypass for another severe shortcoming in the same software ( CVE-2023-49070 , CVSS score: 9.8) that could be weaponized to circumvent authentication and remotely execute arbitrary code. While it was fixed in  Apache OFbiz version 18.12.11  released last month, threat actors have been observed attempting to exploit the flaw, targeting vulnerable instances. The latest findings from VulnCheck show that CVE-2023-51467 can be exploited to execute a payload directly from memory, leaving little to no traces of malicious activity. Security flaws disclosed in Apache OFBiz (e.g.,  CVE-2020-9496 ) have been  exploited  by threat actors ...
