Description
Improper Resource Shutdown or Release vulnerability in Apache Tomcat made Tomcat vulnerable to the made you reset attack
Remediation
Apply vendor security updates immediately. Monitor for exploitation attempts and review access logs.
Executive Summary:
A high-severity vulnerability has been identified in multiple Backup products, designated CVE-2025-48984. This flaw allows a remote attacker with valid domain user credentials to execute arbitrary code on the Backup Server, potentially leading to a complete system compromise. A successful exploit could result in the theft, modification, or destruction of critical backup data, severely impacting business continuity and disaster recovery capabilities.
Vulnerability Details
CVE-ID: CVE-2025-48984
Affected Software: Backup Multiple Products
Affected Versions: See vendor advisory for specific affected versions
Vulnerability: The vulnerability allows for remote code execution (RCE) on the Backup Server. An attacker who has already obtained valid domain user credentials can send specially crafted requests or commands to the server's application interface. Due to improper input validation or a flaw in command handling, the server executes these commands with the privileges of the Backup service account, granting the attacker full control over the underlying operating system.
Business Impact
This vulnerability is rated as High severity with a CVSS score of 8.8. A successful exploit would have a severe business impact, as backup servers are a critical component of an organization's data protection and disaster recovery strategy. An attacker could exfiltrate sensitive data stored in backups, deploy ransomware to encrypt all backup copies, or permanently delete data, rendering recovery from an incident impossible. Furthermore, the compromised server could be used as a pivot point to launch further attacks against the internal network, escalating the security incident.
Remediation Plan
Immediate Action: Apply the security patches provided by the vendor immediately. Priority should be given to any Backup Server instances that are internet-facing or accessible from less trusted network segments. After patching, it is crucial to review access and system logs for any signs of compromise that may have occurred prior to the patch application.
Proactive Monitoring: Implement enhanced monitoring on Backup Servers. Security teams should look for unusual login activity from domain accounts, unexpected processes being spawned by the Backup service, anomalous outbound network connections to unknown IP addresses, and any large or unusual data transfer patterns originating from the server.
Compensating Controls: If immediate patching is not feasible, implement the following compensating controls to reduce the risk of exploitation:
Exploitation Status
Public Exploit Available: false
Analyst Notes: As of November 1, 2025, there are no known public proof-of-concept exploits or active exploitation campaigns targeting this vulnerability. However, due to the high severity and the potential for significant impact, it is highly likely that threat actors will prioritize developing an exploit. The requirement for authentication means attackers may leverage previously compromised credentials to gain initial access.
Analyst Recommendation
Given the critical role of backup systems and the high CVSS score of 8.8, this vulnerability presents a significant risk to the organization. Although CVE-2025-48984 is not currently on the CISA KEV list, its severity warrants immediate attention. We strongly recommend that the vendor-supplied patches be applied on all affected systems as a top priority. In parallel, implement the proactive monitoring and compensating controls outlined above to limit the attack surface and improve detection capabilities. A compromise of the backup infrastructure would be a catastrophic event, and all necessary resources should be allocated to mitigate this threat without delay.
