Description
This security bulletin contains information about 1 vulnerability.
1) Path traversal (CVE-ID: CVE-2018-8741)
CWE-ID: CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:N/SC:L/SI:L/SA:N/E:U/U:Green
The vulnerability allows a remote authenticated attacker to obtain potentially sensitive information on the target system.
The weakness exists due to input validation flaw in 'Deliver.class.php'. A remote attacker can upload a file with a specially crafted filename containing directory traversal characters (e.g., '../'), cause the system to attach arbitrary files to an email message with the privileges of the target PHP process and obtain or delete arbitrary files with the privileges of the target PHP process.
