Java vulnerability analysis and mitigation

Overview

Apache James (Java Apache Mail Enterprise Server) mail server has been identified with a denial-of-service vulnerability (CVE-2024-37358) affecting versions through 3.7.5 and 3.8.0 through 3.8.1. The vulnerability allows both authenticated and unauthenticated users to abuse IMAP literals, potentially causing service disruptions. This issue was disclosed in February 2025 and has been addressed in versions 3.7.6 and 3.8.2 (Security Online, NVD).

Technical details

The vulnerability is classified under CWE-20 (Improper Input Validation) and has received a CVSS v3.1 Base Score of 8.6 (HIGH) with the vector string CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:H. The issue stems from the improper handling of IMAP literals, which can be exploited to trigger unbounded memory allocation and cause extremely long computations (NVD).

Impact

When successfully exploited, this vulnerability can lead to denial of service conditions, effectively shutting down the mail server. This can result in disruption of critical communication channels and potentially impact business operations and cause data loss (Security Online).

Mitigation and workarounds

The Apache James development team has released patches to address this vulnerability in versions 3.7.6 and 3.8.2. Organizations using affected versions are strongly recommended to upgrade to these patched versions immediately. Additionally, administrators should review their firewall rules and access controls to minimize the risk of exploitation (Security Online).
