Analysis Summary

A serious vulnerability affecting Cloud Service Appliances (CSAs) has been actively exploited in the wild, according to Ivanti. With a maximum CVSS score of 10.0, the new vulnerability, with the CVE identifier CVE-2024-8963, has a score of 9.4. Incidentally, the company addressed it in CSA 5.0 and CSA 4.6 Patch 519.

Before 4.6, Path Traversal in the Ivanti CSA Patch 519 makes limited functionality accessible to an unauthenticated remote attacker. The vulnerability might be combined with CVE-2024-8190 (CVSS score: 7.2), according to the report, which would allow an attacker to get around admin authentication and use the appliance to carry out arbitrary commands.

Days after disclosing active exploitation attempts targeting CVE-2024-8190, Ivanti issued a further warning, stating that it knows of only a small number of customers who have been exploited by this vulnerability. This suggests that the activity's threat actors are combining the two vulnerabilities to allow code execution on vulnerable devices.

The vulnerability was added to the U.S. Cybersecurity and Infrastructure Security Agency's (CISA) Known Exploited Vulnerabilities (KEV) catalog as a result of the development, and federal agencies are now required to implement the patches by October 10, 2024. It is strongly advised that users update to CSA version 5.0 as soon as possible since version 4.6 is no longer maintained and is nearing end-of-life.
