Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
1) Deserialization of Untrusted Data
EUVDB-ID: #VU51982
Risk: Medium
CVSSv4.0: 6.3 [CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]
CVE-ID: CVE-2021-1413
CWE-ID:
CWE-502 - Deserialization of Untrusted Data
Exploit availability: No
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 web-based management interface. A remote authenticated attacker can pass specially crafted data to the application and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
MitigationInstall updates from vendor's website.
