Description
This security bulletin contains information about 5 secuirty vulnerabilities.
1) Incorrect default permissions (CVE-ID: CVE-2020-17521)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to incorrect default permissions for temporary files and folders that are set by the application. A local user with access to the system can view contents of files and directories or modify them.
2) Improper input validation (CVE-ID: CVE-2020-5421)
The vulnerability allows a remote authenticated user to read and manipulate data.
The vulnerability exists due to improper input validation within the Core (Spring Framework) component in Oracle Communications Session Report Manager. A remote authenticated user can exploit this vulnerability to read and manipulate data.
3) Protection mechanism failure (CVE-ID: CVE-2019-10086)
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.
4) Server-Side Request Forgery (SSRF) (CVE-ID: CVE-2019-17566)
The disclosed vulnerability allows a remote attacker to perform SSRF attacks.
The vulnerability exists due to insufficient validation of "xlink:href" attributes. A remote attacker can send a specially crafted HTTP request and trick the application to initiate requests to arbitrary systems.
Successful exploitation of this vulnerability may allow a remote attacker gain access to sensitive data, located in the local network or send malicious requests to other servers from the vulnerable system.
5) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2020-11979)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to incorrect patch for vulnerability #VU27924 (CVE-2020-1945). Apache Ant 1.10.8 changed the permissions of temporary files it created so that only the current user was allowed to access them. Unfortunately the fixcrlf task deleted the temporary file and created a new one without said protection, effectively nullifying the effort. This would still allow an attacker to inject modified source files into the build process.
