Critical Security Flaws Affect Ivanti Avalanche, Threatening 30,000 Organizations

Multiple critical security flaws have been reported in Ivanti Avalanche, an enterprise mobile device management solution that’s used by 30,000 organizations.

The vulnerabilities, collectively tracked as CVE-2023-32560, are stack-based buffer overflows in Ivanti Avalanche WLAvanacheServer.

An unauthenticated remote attacker can specify a long hex string or long type 9 item to overflow the buffer, it noted.

Stack-based buffer overflow vulnerabilities occur when the buffer being overwritten is in the stack, leading to a scenario where program execution can be altered to run arbitrary code with elevated privileges.

Ivanti has released Avalanche version 6.4.1 to remediate the problem after it was disclosed in April 2023.

With security flaws in Ivanti software coming under active exploration in recent weeks, it’s imperative that users move quickly to apply the fixes to mitigate potential threats.
