CVE-2021-29802Network attack vector

Privilege escalation via overprivileged application containers

Published Aug 23, 2021 · Updated Sep 16, 2024

Improper privilege management in IBM Resilient App Host before 1.6.1 allows remote attackers to gain privileges via a malicious application. App Host grants hosted application containers permissions beyond those required, so hostile application code operates outside its intended privilege boundary. Exploitation requires a malicious application on App Host and can affect confidentiality, integrity, and availability; IBM discloses no lower-level operation.
