AI Analysis
Technical Summary
CVE-2025-15284 is a denial of service vulnerability in the qs module, which parses query strings in Red Hat OpenShift Container Platform 4.19. The vulnerability arises from improper input validation when parsing arrays using bracket notation (e.g., a[]=value), which bypasses the arrayLimit option intended to restrict array size and prevent resource exhaustion. Exploiting this flaw allows a remote attacker to cause memory exhaustion, leading to application crashes or unresponsiveness and thus denial of service. Red Hat has released OpenShift Container Platform 4.19.23 containing fixes for this issue. The advisory notes that no effective mitigation other than upgrading is currently available. The vulnerability is rated as Important by Red Hat with a CVSS v3 base score of 7.5 (Red Hat's assessment).
Potential Impact
Successful exploitation results in memory exhaustion causing denial of service by crashing or making the application unresponsive. This impacts availability of the affected OpenShift Container Platform services. There is no impact on confidentiality or integrity. The vulnerability affects all OpenShift Container Platform 4.19 versions prior to 4.19.23.
Mitigation Recommendations
Red Hat has released OpenShift Container Platform 4.19.23 which includes fixes for this vulnerability. Users should upgrade to version 4.19.23 or later to remediate the issue. No other mitigation options are currently available or recommended by Red Hat due to limitations in ease of use, applicability, or stability. Follow Red Hat's official upgrade instructions using the OpenShift CLI or web console as documented.
