EUVDB-ID: #VU49570
Risk: Medium
CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2021-24122

CWE-200 - Information exposure

DescriptionThe vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to JSP source code disclosure in some configurations, when serving resources from a network location using the NTFS file system. The root cause was the unexpected behaviour of the JRE API
File.getCanonicalPath() which in turn was caused by the inconsistent
behaviour of the Windows API (FindFirstFileW) in some circumstances.A remote attacker can send a specially crafted request to the application and view the JSP source code.
