Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
EUVDB-ID: #VU58269
Risk: High
CVSSv3.1: 8.8 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H/E:P/RL:O/RC:C]
CVE-ID: CVE-2021-40865
CWE-ID:
CWE-502 - Deserialization of Untrusted Data
Exploit availability: Yes
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to insecure input validation when processing serialized data in the worker services. A remote non-authenticated attacker can send specially crafted request to the server and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
