3) Path traversal
EUVDB-ID: #VU14148
Risk: Low
CVSSv4.0: 6.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2018-14362
CWE-ID:
CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to obtain potentially sensitive information cause DoS condition on the target system.
The vulnerability exists due to forbid characters that may have unsafe interaction with message-cache pathnames, as demonstrated by a '/' character. A remote attacker can conduct directory traversal attack and gain access to arbitrary data or cause the service to crash.
