Deeper analysis

A null pointer dereference vulnerability, tracked as CVE-2024-50318 and assigned CWE-476, affects Ivanti Avalanche versions prior to 6.4.6. The flaw carries a CVSS 3.1 base score of 7.5 with the vector AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H, indicating that a network-reachable condition can terminate service availability without requiring authentication or user interaction.

A remote unauthenticated attacker can send specially crafted requests to trigger the dereference, resulting in a denial-of-service condition that disrupts the Avalanche management platform. No privileges or prior access are needed, and the attack can be mounted directly over the network.

The official Ivanti security advisory for the Q4 2024 release states that the issue is resolved by upgrading to Avalanche 6.4.6 or later. Administrators are advised to apply the update promptly as part of the broader set of patches released for multiple CVEs.

The associated EPSS score has remained flat at 0.0785 with no material increase since disclosure.
