CVE-2023-31473
There is an arbitrary file write in which an empty file can be created anywhere on the filesystem.
Does this matter?
Lower severity and a low EPSS score (3.87%). Track it; it rarely justifies an emergency change on its own.
Description
An issue was discovered on GL.iNet devices before 3.216. There is an arbitrary file write in which an empty file can be created anywhere on the filesystem. This is caused by a command injection vulnerability with a filter applied. Through the software installation feature, it is possible to inject arbitrary parameters in a request to cause opkg to read an arbitrary file name while using root privileges. The -f option can be used with a configuration file.
