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) 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.
3) 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.
4) Code Injection (CVE-ID: CVE-2020-17530)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to improper input validation when processing certain tag's attributes. The application performs double evaluation of the code if a developer applied forced OGNL evaluation by using the %{...} syntax. A remote attacker can send a specially crafted request to the application and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
5) Improper input validation (CVE-ID: CVE-2018-1285)
The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.
The vulnerability exists due to improper input validation within the Simphony Server (Apache log4net) component in Oracle Hospitality Simphony. A remote non-authenticated attacker can exploit this vulnerability to execute arbitrary code.
