CISA@All CISA Advisories //
The Cybersecurity and Infrastructure Security Agency (CISA) has issued a warning regarding a potential broader campaign targeting Software-as-a-Service (SaaS) providers. This alert follows the discovery of unauthorized activity within Commvault's Microsoft Azure environment. CISA believes threat actors may have gained access to client secrets for Commvault's Metallic Microsoft 365 (M365) backup SaaS solution hosted in Azure. This access could allow the threat actors to compromise Commvault's customers' M365 environments where application secrets are stored by Commvault.

The suspected campaign exploits default configurations and elevated permissions in cloud applications, making SaaS companies with weak security a prime target. The initial incident involved a zero-day vulnerability, CVE-2025-3928, in Commvault's Web Server, allowing remote, authenticated attackers to create and execute web shells. Commvault confirmed that Microsoft notified them of the unauthorized activity in February 2025, leading to an investigation and remediation efforts. Despite the breach, Commvault assured customers that there was no unauthorized access to their backup data, and they have rotated app credentials for M365 as a preventative measure.

CISA has provided recommendations for users and administrators to mitigate such threats, including monitoring Entra audit logs for unauthorized modifications, reviewing Microsoft logs for suspicious activity, and implementing conditional access policies to restrict application service principal authentication to approved IP addresses. They also advise reviewing Application Registrations and Service Principals in Entra, restricting access to Commvault management interfaces, and deploying a Web Application Firewall to detect and block path-traversal attempts. These steps aim to strengthen the security posture of SaaS applications and prevent further exploitation of vulnerabilities.

The Cybersecurity and Infrastructure Security Agency (CISA) has issued a warning on April 17, 2025, regarding increased breach risks following a potential compromise of legacy Oracle Cloud servers. This alert comes in response to public reporting of alleged threat activity targeting Oracle customers, though the scope and impact of the activity are currently unconfirmed. CISA's guidance urges organizations and individuals to take immediate steps to secure their IT environments amid claims of a large trove of customer credentials being compromised. The agency is also asking organizations to come forward if they detect suspicious activity or other evidence of a compromise.

CISA is particularly concerned about situations where credential material may be exposed, reused across separate and unaffiliated systems, or embedded into applications and tools. Embedded credential material, which can be hardcoded into scripts, applications, infrastructure templates, or automation tools, is especially difficult to detect and can enable long-term unauthorized access if exposed. The compromise of credentials like usernames, emails, passwords, authentication tokens, and encryption keys can pose a significant risk to enterprise environments.

To mitigate these risks, CISA recommends organizations reset passwords for known affected users, especially those not federated through enterprise identity solutions. Additionally, they should review source code, infrastructure as code templates, automation scripts, and configuration files for hardcoded credentials, replacing them with secure authentication methods supported by centralized secret management. Monitoring authentication logs for anomalous activity, particularly using privileged, service, or federated identity accounts, is also crucial. Finally, CISA advises enforcing phishing-resistant multi-factor authentication for all user and administrator accounts whenever possible.

Bill Mann@CyberInsider //
CISA, along with the NSA, FBI, and international cybersecurity partners, has issued a joint advisory regarding the increasing use of the "fast flux" technique by cybercriminals and nation-state actors. This DNS evasion method allows attackers to rapidly change the DNS records associated with their malicious servers, making it difficult to track and block their activities. This tactic is used to obfuscate the location of malicious servers, enabling them to create resilient and highly available command and control infrastructures while concealing malicious operations.

Fast flux, characterized by quickly changing IP addresses linked to a single domain, exploits weaknesses in network defenses. The advisory, titled 'Fast Flux: A National Security Threat,' urges organizations, internet service providers (ISPs), and security firms to strengthen their defenses against these attacks. Service providers, especially Protective DNS providers (PDNS), are urged to track, share information, and block fast flux activity to safeguard critical infrastructure and national security.

A critical authentication bypass vulnerability, CVE-2025-31161 (previously tracked as CVE-2025-2825), has been identified in CrushFTP, a multi-protocol file transfer server. The vulnerability, which exists in versions 10.0.0 through 10.8.3 and 11.0.0 through 11.3.0, allows attackers to bypass authentication mechanisms, potentially gaining unauthorized access to sensitive data and system resources. CrushFTP privately alerted customers to the issue on March 21, 2025, urging them to apply available patches immediately. BleepingComputer reports that over 1,500 instances remain exposed.

Intrusions exploiting the CVE-2025-2825 vulnerability are already underway, following the emergence of a proof-of-concept exploit. Attackers can gain complete access to affected servers, manipulate files, upload malicious content, and even create admin-level user accounts. Indicators of Compromise include unauthorized access logs, unexpected modifications to user accounts, and unusual file uploads. As a mitigation strategy, CrushFTP recommended activating the demilitarized zone perimeter network option for those unable to promptly update their software.

Google has released a critical security update for its Chrome browser to address a high-severity zero-day vulnerability, identified as CVE-2025-2783. This vulnerability was actively exploited in a sophisticated espionage campaign targeting Russian organizations, specifically media companies, educational institutions, and government entities. According to Kaspersky, the vulnerability allowed attackers to bypass Chrome’s sandbox protections, gaining unauthorized access to affected systems without requiring further user interaction. This incident marks the first actively exploited Chrome zero-day since the start of the year, underscoring the persistent threat landscape faced by internet users.

Kaspersky's investigation, dubbed "Operation ForumTroll," revealed that the attacks were initiated through personalized phishing emails disguised as invitations to the "Primakov Readings" forum. Clicking the malicious link led victims to a compromised website that immediately exploited the zero-day vulnerability. The technical sophistication of the exploit chain points to a highly skilled Advanced Persistent Threat (APT) group. Google urges users to update their Chrome browsers immediately to version 134.0.6998.177/.178 for Windows to mitigate the risk.

CISA has issued a warning to U.S. federal agencies regarding a critical vulnerability, CVE-2024-48248, in NAKIVO's Backup & Replication software. This flaw, an absolute path traversal bug, could allow attackers to access sensitive files, potentially compromising configuration files, backups, and credentials. CISA has added this vulnerability to its Known Exploited Vulnerabilities (KEV) catalog, citing evidence of active exploitation. Agencies are urged to apply necessary mitigations by April 9, 2025.

The vulnerability, affecting versions prior to 10.11.3.86570, was discovered by watchTowr Labs, who also published a proof-of-concept exploit. Successful exploitation could allow an unauthenticated attacker to read arbitrary files on the target host via the "/c/router" endpoint. NAKIVO addressed the issue in November 2024 with version v11.0.0.88174. CISA's directive underscores the need for federal agencies to promptly patch the flaw to secure their networks against potential data exposure.
