Multiple vulnerabilities in Oracle Real-Time Decision Server

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.

3) Incorrect default permissions

EUVDB-ID: #VU27924

Risk: Low

CVSSv4.0: 1.1 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2020-1945

CWE-ID: CWE-276 - Incorrect Default Permissions

Exploit availability: No

Description

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to Apache Ant is using a default temporary directory identified by the Java system property java.io.tmpdir for several tasks and may thus leak sensitive information. The fixcrlf and replaceregexp tasks also copy files from the temporary directory back into the build tree allowing an attacker to inject modified source files into the build process. A local user with access to the system can view contents of files and directories or modify them.

Mitigation

Install update from vendor's website.
