Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
1) Deserialization of Untrusted Data
EUVDB-ID: #VU25833
Risk: High
CVSSv3.1: 8.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2019-14892
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 of a malicious object using commons-configuration 1 and 2 JNDI classes. A remote 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.
Vulnerable software versionsjackson-databind: 2.6.0 - 2.9.9

2) Deserialization of Untrusted Data
EUVDB-ID: #VU25834
Risk: High
CVSSv3.1: 8.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2019-14893
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 of malicious objects using the xalan JNDI gadget when used in conjunction with polymorphic type handling methods such as "enableDefaultTyping()" or when @JsonTypeInfo is using "Id.CLASS" or "Id.MINIMAL_CLASS" or in any other way which ObjectMapper.readValue might instantiate objects from unsafe sources. A remote 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.
