CVE-2020-4534

IBM WebSphere Application Server 7.0, 8.0, 8.5, and 9.0 could allow a local authenticated attacker to gain elevated privileges on the system, caused by improper handling of UNC paths. By scheduling a task with a specially-crafted UNC path, an attacker could exploit this vulnerability to execute arbitrary code with higher privileges. IBM X-Force ID: 182808.
