Description
This security bulletin contains information about 1 vulnerability.
1) Path traversal (CVE-ID: N/A)
CWE-ID: CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
CVSSv4: 8.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a remote attacker to compromise the target system.
The vulnerability exists due to insufficient patch released in version 9.644. The name of the uploaded file is constructed from a user-supplied value passed via
$formSession variable. A remote authenticated attacker can upload an arbitrary file, change the session variable value to a string, containing directory traversal characters (e.g. "../"), bypass the implemented path traversal protection and upload arbitrary file to the system.
Successful exploitation of this vulnerability may result in website compromise.
Remediation
