Technical details
A path traversal vulnerability exists in the copy_banner() function in scheduler/ipp.c prior to version 2.4.20, where the attacker-controlled IPP attributes-natural-language value is unsanitized and used as a directory component beneath DataDir/banners. By injecting path separators, an attacker can traverse to arbitrary files on the system that the CUPS scheduler can access. Successful exploitation requires the job-sheets value to match a registered banner basename and pre-positioned path state such as symlinks, but allows file contents to be copied into a spool object and delivered to an attacker-observable endpoint.
Affected products
