Security Bulletin
This security bulletin contains information about 4 vulnerabilities.
1) Deserialization of untrusted data
EUVDB-ID: #VU13176
Risk: High
CVSSv3.1: 9 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H/E:P/RL:O/RC:C]
CVE-ID: CVE-2016-5003
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 improper deserialization of untrusted Java objects. A remote attacker can send a request that submits a malicious serialized Java object in an <ex:serializable> element and execute arbitrary code with elevated privileges.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
