Deeper analysis
CVE-2024-54677 is an uncontrolled resource consumption vulnerability, assigned CWE-400, that affects the examples web application bundled with Apache Tomcat. It impacts versions 11.0.0-M1 through 11.0.1, 10.1.0-M1 through 10.1.33, and 9.0.0.M1 through 9.0.97, as well as several end-of-life releases including 8.5.0 through 8.5.100. The flaw carries a CVSS 3.1 score of 5.3 and can result in denial of service through excessive resource use.
An unauthenticated attacker with network access can send crafted requests to the examples application, triggering uncontrolled consumption that degrades or disrupts service availability without requiring user interaction or privileges.
Apache Tomcat project advisories and downstream lists such as those from Openwall and Debian recommend upgrading to fixed releases 11.0.2, 10.1.34, or 9.0.98 to resolve the issue.
EPSS for the CVE rose from a low baseline to a peak of 0.0712 on 2025-12-11 before receding to the current value of 0.0123, indicating a period of increased exploitation interest after public disclosure.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Limiting concurrent sessions directly prevents uncontrolled resource consumption by capping the number of active sessions per user or account.
Analysis identifies uncontrolled resource consumption indicative of denial-of-service or abuse attempts.
Contingency plan testing includes resource exhaustion scenarios to verify recovery, making it harder for attackers to sustain exploits that cause uncontrolled consumption.
Updated contingency plans include current procedures to detect, contain, and recover from resource exhaustion, limiting an attacker's ability to sustain impact from uncontrolled consumption.
Alternate site allows resumption of operations if resource exhaustion at the primary site is exploited to cause unavailability.
Alternate telecommunications services enable resumption of essential functions when primary services become unavailable due to uncontrolled resource consumption.
The team can analyze and respond to resource exhaustion incidents, reducing the impact of attacks that exploit uncontrolled consumption weaknesses.
Timely maintenance support and spare parts enable rapid recovery from failures induced by uncontrolled resource consumption, shortening the impact window of denial-of-service attacks.
