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.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.41%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
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.
