Log4j is back!!

Two years after disclosing the Log4Shell vulnerability (CVE-2021-44228), a critical remote code execution (RCE) flaw in the open-source Java logging utility Log4j continues to pose a significant threat. Despite widespread patching efforts, nearly one in four applications still rely on outdated Log4j libraries, rendering them susceptible to exploitation. Notably, the Lazarus hacking group has initiated a new cyber campaign called "Operation Blacksmith," targeting manufacturing, agriculture, and physical security companies globally. Exploiting the Log4Shell vulnerability, the group employs three previously unseen malware families coded in the rarely used D programming language: NineRAT: A remote access trojan (RAT) communicates via the Telegram API for command and control, data exfiltration, and persistence. DLRAT: This trojan and downloader serve to introduce additional payloads and collect system information. BottomLoader: Functioning as a downloader, it fetches and executes payloads, establishes persistence, and exfiltrates files. Over 38% of applications using Log4j remain vulnerable to security issues, including the critical Log4Shell exploit (CVE-2021-44228). This unauthenticated RCE flaw permits attackers to completely control systems utilizing vulnerable Log4j versions (2.0-beta9 through 2.15.0).  Impact: Successful exploitation could allow attackers to control affected systems remotely, steal data, deploy malware, or disrupt operations. Even patched versions of Log4j (2.17) are vulnerable to another RCE bug (CVE-2021-44832). EOL versions of Log4j are susceptible to seven high and critical-rated vulnerabilities, including Log4Shell. Exploited systems can face operational disruptions, data theft, and compromised credentials. Who is Affected? Applications and systems using Log4j versions 2.0-beta9 through 2.15.0 (pre-2015 EOL versions) are directly vulnerable to Log4Shell. Applications using Log4j 2.17 are vulnerable to CVE-2021-44832. Organizations unaware of their open-source software dependencies are at increased risk. Manufacturing, agriculture, and physical security companies are the primary targets, but any organization using vulnerable Log4j is at risk. Remediation: Update Log4j to the latest patched version: Log4j 2.17.1 (Java 8) Log4j 2.13.4 (Java 7) Log4j 2.3.2 (Java 6) Implement Software Composition Analysis (SCA) tools to identify and track vulnerable libraries. Train developers on secure coding practices and open-source software security risks. Limit public exposure of VMware Horizon servers and restrict access with strong authentication. Monitor systems for suspicious activity and implement intrusion detection/prevention systems. How Can Accorian Help: Quick Detection Scan: Accorian can offer a quick detection scan to identify potential Log4Shell vulnerabilities within your systems.  Furthermore, Accorian offers a range of security solutions to help you mitigate the risk of Log4Shell and other cyber threats: Vulnerability Assessment and Penetration Testing: Identify and remediate vulnerabilities in your systems, including Log4j.

WordPress - Critical Vulnerabilities in WS_FTP Server Expose High-Risk Exploitation

Multiple exploitable flaws have been found in numerous versions of the WS_FTP Server, built by Progress Software. One of the most serious is present in WS_FTP Server versions prior to 8.7.4 and 8.8.2, in a module for sending files person-to-person. The module, marketed by Progress Software as the Ad Hoc Transfer Module, is vulnerable to an attack that converts a hypertext transfer protocol message into a malicious object that can execute arbitrary code, a technique known as deserialization.  The identified flaw is a deserialization flaw in WS_FTP, a popular FTP server software. This vulnerability allows malicious actors to execute arbitrary code on affected servers potentially. About 2,900 hosts on the internet were found to be running WS_FTP and had their web servers exposed, making them vulnerable to exploitation. These instances primarily belonged to large enterprises, governments, and educational institutions. Progress Software has since released patches for eight vulnerabilities and strongly recommends that all users update their WS_FTP installations to protect against potential attacks. The updates include a patch for the .NET deserialization vulnerability, tracked as CVE-2023-40044, through which attackers can remotely execute arbitrary code. The U.S. Health Sector Cybersecurity Coordination Center, or HC3, in a Friday alert, said it "strongly encourages all users to follow the manufacturer's recommendation and upgrade to the highest version available - 8.8.2 - to prevent any damage from occurring." Security experts have warned all organizations that use secure file transfer tools to review their documentation to identify how such software can be locked down. Accorian strongly recommends that all users update their WS_FTP installations to protect against potential attacks.

Critical Vulnerability in Ivanti’s Avalanche Enterprise MDM Solution

Ivanti, a leading technology company that offers IT asset management, security, endpoint, and supply chain solutions has released patches for seven critical and high-severity vulnerabilities in Avalanche, its Enterprise Mobile Device Management (MDM) solution. Among the vulnerabilities is the directory traversal flaw tracked down as CVE-2023-32563. It’s the most severe of the flaws with a CVSS score of 9.8. The MDM solution's updateSkin function has this directory traversal flaw that can be exploited without authentication. The problem arises from a user-supplied path not being properly validated before being used in file operations. This vulnerability can be misused by an attacker to execute remote codes.The release also addressed multiple stack-based buffer overflow bugs collectively tracked down as CVE-2023-32560 with a CVSS score of 8.8. These were discovered in the Wavelink Avalance Manager, which processes data using a fixed-size stack-based buffer. By delivering a specially written message to the service, an adversary can take advantage of this and potentially cause code execution or disrupt the service. In addition, two other high-severity remote code execution vulnerabilities CVE-2023-32562 and CVE-2023-32564 and three authentication bypass flaws CVE-2023-32561, CVE-2023-32565, and CVE-2023-32566 present in various components of the MDM solution were patched.Although none of these problems have been reported as being exploited in the wild, Accorian strongly recommends that all users of Avalanche update it to version 6.4.1.207, released earlier this month.
