AI Analysis
Technical Summary
CVE-2025-66487 is a resource allocation vulnerability in IBM Aspera Shares (versions 1.9.9 through 1.11.0) where the application fails to enforce rate limiting on the frequency of emails sent by authenticated users. This lack of throttling can lead to excessive resource consumption, resulting in email flooding or denial of service. The vulnerability is classified under CWE-770. The CVSS 3.1 base score is 2.7, reflecting low impact primarily due to the requirement of authenticated access and limited impact on confidentiality and integrity.
Potential Impact
An authenticated user can exploit this vulnerability to send emails at an unregulated frequency, potentially overwhelming the email system or causing denial of service conditions. There is no impact on confidentiality or integrity reported. The overall impact is limited to availability degradation.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, organizations should consider implementing external rate limiting or monitoring controls on email sending frequency for authenticated users to mitigate potential abuse.
