Security News > 2023 > August > Ivanti Avalanche impacted by critical pre-auth stack buffer overflows
Two stack-based buffer overflows collectively tracked as CVE-2023-32560 impact Ivanti Avalanche, an enterprise mobility management solution designed to manage, monitor, and secure a wide range of mobile devices.
The flaws are rated critical and are remotely exploitable without user authentication, potentially allowing attackers to execute arbitrary code on the target system.
An attacker sending specially crafted data packets containing hex strings or a list of decimal strings separated by ";" can cause a buffer overflow due to a fixed-size stack-based buffer used to store the converted data.
Stack-based buffer overflows concern the overwrite of regions allocated on the stack, a memory region that stores the program's local variables and return addresses, making it possible to direct the program to execute malicious code.
Ivanti software is used in critical systems and settings, so threat actors are constantly looking for critical-severity vulnerabilities that constitute potential gateways for attacks.
