CVE-2024-8963: 
Ivanti Cloud Services Appliance vulnerability analysis and mitigation

CVE-2024-8963 is a path traversal vulnerability affecting Ivanti Cloud Services Appliance (CSA) before version 4.6 Patch 519. This vulnerability allows remote unauthenticated attackers to access restricted functionality within the appliance. The vulnerability was discovered and disclosed in September 2024, with Ivanti releasing a security advisory on September 19, 2024. The affected systems include Ivanti CSA version 4.6 and prior versions (CISA Alert, NVD).

The vulnerability is classified as CWE-22 (Improper Limitation of a Pathname to a Restricted Directory). It allows attackers to exploit a path traversal flaw in the /client/index.php resource to gain unauthorized access to other resources like users.php and reports.php. The vulnerability received a CVSS v3.1 base score of 9.1 CRITICAL (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N) from NVD, while Ivanti assigned it a score of 9.4 CRITICAL (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:L) (Fortinet Research).

The vulnerability enables attackers to bypass authentication and access restricted functionality. When chained with other vulnerabilities like CVE-2024-8190, attackers can gain complete control of affected systems, access user credentials, and potentially move laterally within the network (CISA Alert, Fortinet Research).

Ivanti recommends users upgrade to CSA version 5.0, as version 4.6 is end-of-life and no longer supported. Organizations should consider CSA 4.6.x credentials and sensitive data as compromised and implement appropriate incident response measures. CISA urges users and administrators to review the Ivanti security advisory and apply the necessary updates immediately (CISA Alert).
