Description

This security bulletin contains information about 4 secuirty vulnerabilities.


1) XML External Entity injection (CVE-ID: CVE-2019-12415)

The vulnerability allows a remote attacker to gain access to sensitive information.

The vulnerability exists due to insufficient validation of user-supplied XML input when using the tool XSSFExportToXml to convert user-provided Microsoft Excel documents. A remote attacker can pass a specially crafted XML code to the affected application and read files from the local filesystem or from internal network resources on the system or initiate requests to external systems.

Successful exploitation of the vulnerability may allow an attacker to view contents of arbitrary file on the server or perform network scanning of internal and external infrastructure.


2) Session Fixation (CVE-ID: CVE-2019-17563)

The vulnerability allows a remote attacker to perform a session fixation attack.

The vulnerability exists due to a race condition when FORM authentication is used in Apache Tomcat. A remote attacker can use a narrow window to perform a session fixation attack.


3) Use-after-free (CVE-ID: CVE-2019-10082)

The vulnerability allows a remote attacker to perform denial of service (DoS) attack.

The vulnerability exists due to a use-after-free error within the mod_http2 when handling connection shutdown. A remote attacker can send specially crafted requests to the affected server and make the mod_http2 to read memory that was already freed.



4) Deserialization of untrusted data (CVE-ID: CVE-2017-5645)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The weakness exists receiving serialized log events from another application when using the TCP socket server or UDP socket server. A remote attacker can submit a specially crafted binary payload, when deserialized, and execute arbitrary code.

Successful exploitation of the vulnerability may result in system compromise.
