CISA Alert: Three Actively Exploited Vulnerabilities Added to Catalog in April 2025

As we near the end of April 2025, the Cybersecurity and Infrastructure Security Agency (CISA) has issued a critical alert that underscores the ever-evolving threat landscape. On April 28, 2025, CISA added three new vulnerabilities to its Known Exploited Vulnerabilities Catalog, highlighting active exploitation by malicious actors. This update serves as an urgent reminder for organizations across all sectors to prioritize vulnerability management and remediation to safeguard their systems. Here's a detailed breakdown of the latest additions and their implications.

Newly Identified Exploited Vulnerabilities

• Broadcom Brocade Fabric OS Code Injection Vulnerability: This flaw allows attackers to inject malicious code into affected systems, potentially leading to unauthorized access and control. Broadcom Brocade Fabric OS is widely used in storage area networks, making this a significant concern for enterprises with large data infrastructures.
• Qualitia Active! Mail Stack-Based Buffer Overflow Vulnerability: A buffer overflow in Qualitia Active! Mail can be exploited to execute arbitrary code, posing risks to email systems and user data. Organizations relying on this software for communication are advised to apply patches immediately.
• Commvault Web Server Unspecified Vulnerability: While specifics are limited, this vulnerability in Commvault Web Server software has been confirmed as actively exploited. It represents a potential entry point for attackers targeting backup and recovery systems.

Why This Matters

These vulnerabilities are not theoretical risks—they are currently being exploited in the wild, as evidenced by CISA’s decision to include them in the Known Exploited Vulnerabilities Catalog. Established under Binding Operational Directive (BOD) 22-01, this catalog identifies Common Vulnerabilities and Exposures (CVEs) that pose significant risks, particularly to federal enterprises. Although BOD 22-01 applies specifically to Federal Civilian Executive Branch (FCEB) agencies, CISA strongly urges all organizations—private and public—to address these threats promptly.

Impact and Urgency

• Widespread Risk: These vulnerabilities affect critical systems such as network infrastructure, email platforms, and backup solutions, which are integral to organizational operations.
• Active Exploitation: Malicious actors are already leveraging these flaws to compromise systems, potentially leading to data breaches, ransomware deployment, or system downtime.
• Federal Mandate: FCEB agencies are required to remediate these vulnerabilities by specified due dates to protect against active threats, setting a benchmark for urgency in the private sector as well.

Recommended Actions

• Patch Immediately: Check for updates from Broadcom, Qualitia, and Commvault, and apply patches or mitigations as soon as possible to address these vulnerabilities.
• Monitor Systems: Deploy intrusion detection and monitoring tools to identify any signs of exploitation or unusual activity related to these CVEs.
• Prioritize Vulnerability Management: Adopt a proactive approach by regularly reviewing CISA’s Known Exploited Vulnerabilities Catalog and integrating timely remediation into your cybersecurity strategy.
• Educate Teams: Ensure IT and security personnel are aware of these threats and understand the importance of swift action to mitigate risks.

Conclusion

The addition of these three vulnerabilities to CISA’s catalog on April 28, 2025, is a stark reminder of the relentless pace of cyber threats facing organizations today. As malicious actors continue to exploit known flaws, staying ahead requires vigilance, rapid response, and a commitment to cybersecurity best practices. Whether you’re part of a federal agency or a private enterprise, now is the time to assess your systems, apply necessary patches, and fortify your defenses against these actively exploited threats.
