Last modified
CVE-2020-4433 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. Certain IBM Aspera applications are vulnerable to a stack-based buffer overflow, caused by improper bounds checking. This could allow a remote attacker with intimate knowledge of the server to execute arbitrary code on the system with the privileges of root or cause server to crash. EPSS estimates a 5.13% chance of exploitation in the next 30 days.
