Weekly Vulnerability Summary by CISA – February 12, 2024; New ICS Advisories

The Cybersecurity and Infrastructure Security Agency (CISA) has once again issued a summary of the latest vulnerabilities. The latest CISA weekly vulnerability summary lists vulnerabilities identified between February 9 and February 17, 2024.

In this blog post, we will highlight critical and high-severity vulnerabilities featured in the CISA weekly vulnerability summary, which could significantly affect organizations’ digital resilience. As we explore this weekly roundup, our focus is on highlighting the most urgent threats, necessitating immediate attention and proactive mitigation efforts.

Overview of the Latest Significant Vulnerabilities

Diverse products are vulnerable to a wide range of critical and high-severity issues. In this review of the weekly CISA weekly vulnerability summary, we will explore vulnerabilities in Apache Solr, Adobe products, SolarWinds, Fortinet, GitHub, and more, highlighting a variety of security issues.

Furthermore, notable vulnerabilities affecting organizations such as IBM, Intel, Dell, Siemens, and SAP have also been mentioned in CISA’s weekly vulnerability summary.

Unrestricted File Upload in Apache Solr:

A high-severity vulnerability, CVE-2023-50386 (CVSS: 8.8), has been discovered in Apache Solr. This vulnerability allows the unrestricted upload of Java jar and class files via the ConfigSets API, leading to potential security risks.

During Solr Collections backup, ConfigSet files are saved to disk using the LocalFileSystemRepository; it poses a threat if these files are stored in directories accessible by Solr’s ClassPath/ClassLoaders, because then the jar and class files would be available to use with any ConfigSet, trusted or untrusted.

Vulnerabilities in Multiple Adobe Products:

Included in the list are also Adobe vulnerabilities affecting FrameMaker and Commerce, tracked as CVE-2024-20738, CVE-2024-20719, and CVE-2024-20720. CISA previously highlighted these vulnerabilities once security updates became available.

The Adobe vulnerabilities are deemed critical and encompass Security Feature Bypass, Cross-site Scripting (XSS), and OS Command Injection issues. For further insights into these vulnerabilities, you can explore another SOCRadar blog post: “CISA Highlights Critical Adobe Security Updates for Acrobat, Magento, and More (CVE-2024-20738, CVE-2024-20719, CVE-2024-20720).”

Severe Command Injection in F5 BIG-IP:

CVE-2024-22093 (CVSS: 8.7), affecting F5 BIG-IP, occurs when operating in appliance mode. This vulnerability involves an authenticated remote command injection flaw within an undisclosed iControl REST endpoint on multi-bladed systems. A successful exploit can enable attackers to breach security boundaries.

Alongside the critical vulnerabilities identified, a high-severity improper privilege management vulnerability in Fortinet FortiClientEMS, CVE-2023-45581 (CVSS: 8.8), allows a Site administrator with Super Admin privileges to execute global administrative operations affecting other sites via crafted HTTP or HTTPS requests.

Multiple Command Injection Flaws in GitHub Enterprise Server:

Multiple critical command injection vulnerabilities with CVSS scores of 9.1 have been identified, affecting GitHub Enterprise Server. These vulnerabilities enable an attacker with an editor role in the Management Console to gain admin SSH access to the appliance. They were reported through the GitHub Bug Bounty program, and their CVE identifiers are as follows:

Vulnerabilities Addressed in the Latest Microsoft Patch Tuesday:

CISA’s weekly vulnerability summary lists critical Microsoft vulnerabilities; among them are CVE-2024-21410 and CVE-2024-21413, which were addressed in the most recent Patch Tuesday update.

CVE-2024-21410 represents a privilege escalation vulnerability in Microsoft Exchange Server. The advisory for this vulnerability has been updated post-Patch Tuesday to clarify its exploitation as a zero-day threat.
