CVE-2024-8963
Path Traversal in the Ivanti CSA before 4.6 Patch 519 allows a remote unauthenticated attacker to access restricted functionality.
do firstAs Ivanti CSA has reached End-of-Life status, users are urged to remove CSA 4.6.x from service or upgrade to the 5.0.x line of supported solutions, as future vulnerabilities on the 4.6.x version of CSA are unlikely to receive security updates.
Can a WAF block it? Yes. The vulnerability is a path traversal allowing remote unauthenticated attackers to access restricted functionality via HTTP requests. Such attacks typically include '../' sequences in the URL path, which a WAF can detect and block without affecting normal users. A WAF rule can match '../' sequences in the URL path. No tracked WAF vendor has published a rule for this CVE yet, so you would write it yourself.
What a custom rule would match: '../' sequences in the URL path
