CVE-2025-9784
HIGHEPSS 82th pctl7.5
CVSS v3
Description
A flaw was found in Undertow where malformed client requests can trigger server-side stream resets without triggering abuse counters. This issue, referred to as the "MadeYouReset" attack, allows malicious clients to induce excessive server workload by repeatedly causing server-side stream aborts. While not a protocol bug, this highlights a common implementation weakness that can be exploited to cause a denial of service (DoS).

Common questions
How do I fix CVE-2025-9784?
Published advisories record a fix for 445 affected products. The "How to fix" section on this page lists the fixed version and source advisory for each one, so apply the entry matching what you actually run.
Is CVE-2025-9784 being actively exploited?
Not that we know of. CVE-2025-9784 is not in the CISA Known Exploited Vulnerabilities catalog. Its EPSS score of 2.3% is the estimated probability that it will be exploited in the next 30 days. That is higher than 82% of all scored CVEs.
How severe is CVE-2025-9784?
CVE-2025-9784 has a CVSS v3 base score of 7.5, rated high. CVSS rates the technical impact if the vulnerability is exploited, not how likely that is, so weigh it alongside the exploit-prediction score when you decide what to patch first.
What does CVE-2025-9784 affect?
Published advisories record a fix for undertow (Debian), eap7-apache-commons-beanutils (Red Hat / RHEL), eap7-apache-commons-beanutils (Rocky), eap7-apache-cxf (Rocky), and 441 more. Only products with a sourced advisory are listed, so treat this as what we can cite rather than a complete inventory.
