Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
1) Deserialization of untrusted data
EUVDB-ID: #VU11268
Risk: High
CVSSv3.1: 7.8 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2018-7489
CWE-ID:
CWE-502 - Deserialization of Untrusted Data
Exploit availability: No
DescriptionThe vulnerability allows a remote unauthenticated attacker to bypass security restrictions and execute arbitrary code on the target system.
The weakness exists in the readValue method due to improper validation of user-input. A remote attacker can send malicious JSON input, bypass security restrictions and execute arbitrary code with elevated privileges.
Successful exploitation of the vulnerability may result in system compromise.
Install update from vendor's website.
