Security Bulletin
This security bulletin contains information about 13 vulnerabilities.
1) Improper input validation
EUVDB-ID: #VU15178
Risk: Medium
CVSSv3.1: 7.5 [CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2018-15408
CWE-ID:
CWE-20 - Improper input validation
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to improper validation of Advanced Recording Format (ARF) and Webex Recording Format (WRF) files. A remote unauthenticated attacker can trick the victim into opening a specially crafted ARF or WRF file sent via a link or an email attachment and execute arbitrary code
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
