1) Protection mechanism failure

EUVDB-ID: #VU20844

Risk: Low

CVSSv4.0: 1.7 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2019-10086

CWE-ID: CWE-693 - Protection Mechanism Failure

Exploit availability: No

Description

The vulnerability allows a remote attacker to bypass certain security restrictions.

The vulnerability exist due to Beanutils is not using by default the a special BeanIntrospector class in PropertyUtilsBean that was supposed to suppress the ability for an attacker to access the classloader via the class property available on all Java objects. A remote attacker can abuse such application behavior against applications that were developed to rely on this security feature.

Mitigation

Install update from vendor's website.

2) Resource management error

EUVDB-ID: #VU22185

Risk: Medium

CVSSv4.0: 6.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2019-12402

CWE-ID: CWE-399 - Resource Management Errors

Exploit availability: No

Description

3) Input validation error

EUVDB-ID: #VU21593

Risk: Medium

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:Green]

CVE-ID: CVE-2019-16943

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

Description

The vulnerability allows a remote attacker to compromise the affected application.

The vulnerability exists due to a Polymorphic Typing issue when processing JSON requests  within the com.p6spy.engine.spy.P6DataSource component. A remote attacker can send specially crafted JSON data to an RMI service endpoint and execute arbitrary code on he system.

Successful exploitation of the vulnerability requires that Default Typing is enabled (either globally or for a specific property) for an externally exposed JSON endpoint, the service has has the p6spy (3.8.6) jar in the classpath, and an attacker can find an RMI service endpoint to send requests to.

Mitigation

Install update from vendor's website.
