EUVDB-ID: #VU15218
Risk: Low
CVSSv3.1: 3.6 [CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:N/I:N/A:L/E:U/RL:O/RC:C]
CVE-ID: CVE-2018-15396
CWE-ID:
CWE-20 - Improper input validation
Exploit availability: No
DescriptionThe vulnerability allows a remote high-privileged attacker to cause DoS condition on the target system.
The vulnerability exists due to improper restriction of the maximum size of certain files that can be written to disk. A remote attacker who has valid administrator credentials for an affected system can send a specially crafted, remote connection request, write a file that consumes most of the available disk space on the system and cause application functions to operate abnormally and lead to a DoS condition.
MitigationThe vulnerability has been fixed in the version 12.5(0.97000.301), 12.0(1.22900.7), 12.5(0.202), 12.0(1.53).

CVE-ID: CVE-2018-15426
CWE-ID:
CWE-79 - Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
Exploit availability: No
DescriptionThe disclosed vulnerability allows a remote high-privileged attacker to perform cross-site scripting (XSS) attacks.
