Vulnerabilities description

  • CVE-2025-48988

    A denial-of-service (DoS) vulnerability has been identified in Apache Tomcat, concerning its handling of upload limits. A remote attacker could exploit this flaw by sending a specially crafted request containing an excessively large number of multipart sections. This malicious request can trigger excessive memory consumption on the Tomcat server, ultimately leading to resource exhaustion and a denial-of-service condition.

  • CVE-2025-48989

    A flaw was found in Apache Tomcat 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).

  • CVE-2025-49125

    A flaw has been discovered in path handling logic in Apache Tomcat. When using either PreResources or PostResources mounted on a non-root path, it is possible to access resources via an unexpected path. This may result in leaking of files on those paths.

  • CVE-2025-52520

    A denial of service flaw was found in Apache Tomcat. For some unlikely configurations of multipart upload, an integer overflow vulnerability may lead to a denial of service via bypassing size limits.

  • CVE-2025-53506

    A denial of service flaw was found in Apache Tomcat. An uncontrolled resource consumption vulnerability, where an HTTP/2 client fails to acknowledge the initial settings frame that reduces the maximum permitted concurrent streams, could result in a denial of service.

  • CVE-2025-48976

    A denial-of-service (DoS) vulnerability has been discovered in the Apache Commons FileUpload library. The flaw stems from insufficient limits placed on multipart headers during file uploads. A remote attacker could exploit this by sending a specially crafted request with an excessively large number of multipart headers. This malicious input can lead to uncontrolled memory consumption within applications utilizing the library, exhausting system resources and causing a denial of service.
