What is CVE-2021-48015?

JeeWMS prior to commit 0a610e8 is susceptible to an unauthenticated path traversal vulnerability, permitting remote attackers to access arbitrary files on the server. By manipulating the dbPath parameter, attackers can issue GET requests to /systemController/showOrDownByurl.do, utilizing ../ sequences to navigate the file system and bypass security mechanisms like AuthInterceptor. This flaw can lead to unauthorized exposure of sensitive files. The exploitation activity for this vulnerability was first noted by the Shadowserver Foundation on October 17, 2023.
