2) Deserialization of Untrusted Data

EUVDB-ID: #VU19018

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-2019-12384

CWE-ID: CWE-502 - Deserialization of Untrusted Data

Exploit availability: No

Description

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to software allows the logback-core class to process polymorphic deserialization. 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.

Mitigation

Install update from vendor's website.

3) XXE attack

EUVDB-ID: #VU17777

Risk: Low

CVSSv3.1: 5.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:L/E:U/RL:O/RC:C]

CVE-ID: CVE-2018-14720

CWE-ID: CWE-611 - Improper Restriction of XML External Entity Reference ('XXE')

Exploit availability: No

Description

The disclosed vulnerability allows a remote attacker to perform XXE attacks.

The vulnerability exists due to fail to block unspecified Java Development Kit (JDK) classes from polymorphic deserialization. A remote attacker can send a specially crafted request that submits malicious input, conduct an XXE attack to access sensitive information, bypass security restrictions, or cause a denial of service (DoS) condition on the targeted system. 

Mitigation

Install update from vendor's website.

4) Code Injection

EUVDB-ID: #VU25469

Risk: Medium

CVSSv3.1: 5.1 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:L/E:P/RL:O/RC:C]

CVE-ID: CVE-2020-8840

CWE-ID: CWE-94 - Improper Control of Generation of Code ('Code Injection')

Exploit availability: Yes

Description

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to absence of xbean-reflect/JNDI gadget blocking. A remote attacker can pass specially crafted input to the application and execute arbitrary Java code on the system, as demonstrated by org.apache.xbean.propertyeditor.JndiConverter.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

Mitigation

Install update from vendor's website.

5) Input validation error

EUVDB-ID: #VU17779

Risk: High

CVSSv3.1: 8.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2018-19361

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

Description

The disclosed vulnerability allows a remote attacker to cause DoS condition or execute arbitrary code.

The vulnerability exists due to fail to block the openjpa class from polymorphic deserialization. A remote attacker can send a specially crafted request that submits malicious input to perform unauthorized actions on the system, which could allow the attacker to execute arbitrary code or cause a denial of service (DoS) condition.
