Who should care

Administrators and security teams running Apache Tomcat, especially in internet-facing or cloud-hosted environments, should prioritize this issue because it is on CISA’s KEV catalog.

Technical summary

The official records identify the issue as a path equivalence vulnerability in Apache Tomcat. The supplied source set does not provide deeper technical mechanics, so the safest assumption is that Tomcat path handling or normalization may allow unintended equivalence between paths. CISA’s KEV listing means the vulnerability is considered known exploited and warrants urgent remediation planning.

Defensive priority

High. CISA listed CVE-2025-24813 in KEV on 2025-04-01 with a remediation deadline of 2025-04-22, so affected environments should be reviewed and addressed immediately.

Recommended defensive actions

  • Check whether Apache Tomcat is present in your environment, including embedded or bundled deployments.
  • Apply vendor-provided mitigations or updates as directed by Apache.
  • If mitigations are unavailable, discontinue use of the affected product or deployment path.
  • For cloud services, follow applicable CISA BOD 22-01 guidance.
  • Validate exposure in internet-facing and externally accessible systems first.
  • Track remediation against the CISA KEV due date of 2025-04-22.
