Description
This security bulletin contains information about 6 secuirty vulnerabilities.
1) Cross-site scripting (CVE-ID: CVE-2019-10241)
The disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.
The vulnerability exists due to insufficient sanitization of user-supplied data in DefaultServlet or ResourceHandler that is configured for showing a Listing of directory contents. A remote attacker can trick the victim to follow a specially crafted link and execute arbitrary HTML and script code in user's browser in context of vulnerable website.
Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.
2) Improper input validation (CVE-ID: CVE-2019-10247)
The vulnerability allows a remote non-authenticated attacker to gain access to sensitive information.
The vulnerability exists due to improper input validation within the Integrator Acquistion System (Eclipse Jetty) component in Oracle Endeca Information Discovery Integrator. A remote non-authenticated attacker can exploit this vulnerability to gain access to sensitive information.
3) Race condition (CVE-ID: CVE-2020-27216)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a race condition. On Unix like systems, the system's temporary directory is shared between all users on that system. A collocated user can observe the process of creating a temporary sub directory in the shared temporary directory and race to complete the creation of the temporary subdirectory. If the attacker wins the race then they will have read and write permission to the subdirectory used to unpack web applications, including their WEB-INF/lib jar files and JSP files. If any code is ever executed out of this temporary directory, this can lead to a local privilege escalation vulnerability.
4) Improper input validation (CVE-ID: CVE-2020-27223)
The vulnerability allows a remote non-authenticated attacker to perform service disruption.
The vulnerability exists due to improper input validation within the General (Eclipse Jetty) component in Oracle REST Data Services. A remote non-authenticated attacker can exploit this vulnerability to perform service disruption.
5) Incorrect permission assignment for critical resource (CVE-ID: CVE-2020-28169)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to incorrect permissions assignment for the bin directory in the td-agent-builder plugin for Fluentd. A local user overwrite arbitrary files in the bin directory, which are later executed with elevated privileges.
6) Insufficient Session Expiration (CVE-ID: CVE-2021-34428)
The vulnerability allows an attacker to gain access to sensitive information.
The vulnerability exists due to insufficient session expiration issue. If an exception is thrown from the SessionListener#sessionDestroyed() method, then the session ID is not invalidated in the session ID manager. On deployments with clustered sessions and multiple contexts this can result in a session not being invalidated.
