Apache Tomcat 9.0.1 – 9.0.108
Raw vector
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:HSummary
CVE-2025-48989 is a high-severity Improper Resource Shutdown or Release (CWE-404) vulnerability in Apache Tomcat. Its CVSS base score is 7.5 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked in the top 12% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SA-8 (Security and Privacy Engineering Principles) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2025-48989 is an Improper Resource Shutdown or Release vulnerability, tracked as CWE-404, that leaves Apache Tomcat exposed to the "made you reset" attack. It affects Tomcat releases 11.0.0-M1 through 11.0.9, 10.1.0-M1 through 10.1.43, and 9.0.0.M1 through 9.0.107, with older end-of-life versions also potentially impacted. The flaw carries a CVSS 3.1 base score of 7.5, reflecting network-accessible exploitation that can produce high impact to availability without requiring authentication or user interaction.
An unauthenticated remote attacker can send crafted requests that trigger improper connection or resource release, resulting in denial of service against the Tomcat instance. Because the attack requires no privileges and can be launched over the network with low complexity, it is feasible from any internet-facing position.
Apache Tomcat project advisories and coordinated disclosures, including the Apache announcement and the CERT/CC entry, recommend immediate upgrade to the fixed releases 11.0.10, 10.1.44, or 9.0.108. Siemens and other downstream vendors have mirrored these upgrade instructions in their own security bulletins.
EPSS remains low and unchanged at 0.0282, indicating no material increase in observed exploitation interest since disclosure.

Mitigating Controls
Mitigating Controls (NIST 800-53 r5) AI
Developer testing and evaluation can discover missing or incorrect resource releases after code is written.
Engineering principles can require explicit resource acquisition/release patterns that stop improper shutdown from being introduced.
Priority-based resource allocation limits the blast radius when released resources are not returned to the pool.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Secure SDLC practices directly include coding standards for correct resource allocation and release.
Runtime monitoring can detect resource exhaustion caused by improper shutdown or release.
Lifecycle management of assets can encompass proper resource release at end-of-life or shutdown.
Capacity management helps surface leaks from unreleased resources but does not prevent the coding flaw.

Including restart, recovery and media-handling instructions reduces the likelihood that resources or sensitive data will be left in an exposed or improperly released state after a failure.
