Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
1) Deserialization of untrusted data
EUVDB-ID: #VU11268
Risk: High
CVSSv4.0: 7.2 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber]
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.

2) Deserialization of untrusted data
EUVDB-ID: #VU9128
Risk: High
CVSSv4.0: 8.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P/U:Amber]
CVE-ID: CVE-2017-7525
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 weakness exists due to a deserialization flaw in the jackson-databind component. A remote attacker can send a specially crafted input to the readValue method of the ObjectMapper and execute arbitrary code with privileges of the target service.
Successful exploitation of the vulnerability may result in system compromise.
