Ivanti warned of three new security vulnerabilities (CVE-2024-9379, CVE-2024-9380, and CVE-2024-9381) in its Cloud Service Appliance (CSA) that are actively exploited in attacks in the wild.
Below are the descriptions of the three vulnerabilities:
Threat actors are chaining these three vulnerabilities with the CSA zero-day CVE-2024-8963 (CVSS score of 9.4) that the software firm addressed in September.
Threat actors could exploit these vulnerabilities to carry out SQL injection attacks, execute arbitrary code via command injection, and bypass security restrictions by abusing a path traversal weakness on vulnerable CSA gateways.
“We are aware of a limited number of customers running CSA 4.6 patch 518 and prior who have been exploited when CVE-2024-9379, CVE-2024-9380 or CVE-2024-9381 are chained with CVE-2024-8963.” reads the advisory published by Ivanti. “We have no evidence of any other vulnerabilities being exploited in the wild. These vulnerabilities do not impact any other Ivanti products or solutions.”
The company is not aware of attacks against customers running CSA 5.0.
“Ivanti recommends reviewing the CSA for modified or newly added administrative users. While inconsistent, some attempts may show up in the broker logs which are local to the system. We also recommend reviewing EDR alerts, if you have installed EDR or other security tools on your CSA. As this is an edge device, Ivanti strongly recommends using a layered approach to security and installing an EDR tool on the CSA.” concludes the advisory. “If you suspect compromise, Ivanti’s recommendation is that you rebuild your CSA with version 5.0.2.”
Customers should upgrade to CSA 5.0.2 to fix the vulnerabilities.
Besides updating to the latest version (5.0.2), the company is recommending users to review the appliance for modified or newly added administrative users to look for signs of compromise, or check for alerts from endpoint detection and response (EDR) tools installed on the device.
In September, the U.S. Cybersecurity and Infrastructure Security Agency (CISA) added Ivanti Cloud Services Appliance path traversal vulnerability CVE-2024-8190 (CVSS score of 9.4) to its Known Exploited Vulnerabilities (KEV) catalog.
Ivanti warned of a new Cloud Services Appliance (CSA) vulnerability, tracked as CVE-2024-8963 (CVSS score of 9.4), actively exploited in attacks in the wild against a limited number of customers. The vulnerability is a path traversal security issue.
A remote, unauthenticated attacker could exploit the vulnerability to access restricted functionality. An attacker could chain the issue with CVE-2024-8190 to bypass admin authentication and execute arbitrary commands on the appliance.
