Deeper analysis
CVE-2024-27975 is a use-after-free vulnerability (CWE-416) in the WLAvalancheService component of Ivanti Avalanche versions prior to 6.4.3. The flaw carries a CVSS 3.1 score of 8.8 and permits remote code execution with SYSTEM-level privileges on the affected server.
A remote attacker who already possesses valid credentials can trigger the vulnerability over the network to execute arbitrary commands. Because the service runs with SYSTEM rights, successful exploitation grants full control of the host without further privilege escalation.
The vendor’s advisory for Avalanche 6.4.3 states that the release contains security hardening and fixes for this and other CVEs; organizations are advised to upgrade to that version to eliminate the exposure.
The EPSS score has remained flat at 0.0511 since disclosure, indicating no observed surge in exploitation interest to date.
