CVE-2026-24329 (GCVE-0-2026-24329)

Vulnerability from cvelistv5 – Published: 2026-08-11 02:35 – Updated: 2026-08-11 02:35

Title

Wildfly-core: wildfly core: denial of service via malformed payload injection by an authenticated administrative user.

Summary

A flaw was found in wildfly-core. A remote user authenticated as an administrative user can inject a malformed payload into the Inet Address field through the Management Model. This injection causes the server to crash and become unrecoverable, as the payload is written into the standalone.xml configuration file. Manual intervention is required to restore server operation, leading to a denial of service.

Severity

4.9 (Medium)

Configure firewall rules to limit inbound connections to the management port (e.g., 9990) from only authorized IP addresses or subnets. Additionally, ensure that only necessary and trusted administrative users have credentials for the WildFly management console.\n\nExample firewall rule using `firewalld` on Red Hat Enterprise Linux:\n`firewall-cmd --permanent --add-rich-rule=\u0027rule family=\"ipv4\" source address=\"\u003cTRUSTED_IP_ADDRESS\u003e\" port port=\"9990\" protocol=\"tcp\" accept\u0027`\n`firewall-cmd --reload`\n\nThis mitigation limits the attack surface by restricting who can access the administrative interface, thereby reducing the risk of an authenticated administrative user exploiting this vulnerability. Note that applying firewall rules may impact legitimate remote management operations if not configured correctly."
