SB2022042223 - Multiple vulnerabilities in Oracle Communications Messaging Server

Description

This security bulletin contains information about 5 secuirty vulnerabilities.

1) Inconsistent interpretation of HTTP requests (CVE-ID: CVE-2021-43797)

The vulnerability allows a remote attacker to preform HTTP request smuggling attacks.

The vulnerability exists due to improper validation of HTTP requests when processing control chars present at the beginning / end of the header name. A remote attacker can send a specially crafted HTTP request to the server and smuggle arbitrary HTTP headers.

Successful exploitation of vulnerability may allow an attacker to poison HTTP cache and perform phishing attacks.

2) Code Injection (CVE-ID: CVE-2021-44832)

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

The vulnerability exists due to improper input validation. A remote user with permission to modify the logging configuration file can construct a malicious configuration using a JDBC Appender with a data source referencing a JNDI URI which can execute remote code.

3) XML External Entity injection (CVE-ID: CVE-2021-33813)

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

The vulnerability exists due to insufficient validation of user-supplied XML input within the SAXBuilder. A remote attacker can pass a specially crafted XML code to the affected application and view contents of arbitrary files 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.

4) Information disclosure (CVE-ID: CVE-2021-40690)

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

The vulnerability exists due to an issue where the "secureValidation" property is not passed correctly when creating a KeyInfo from a KeyInfoReference element. A remote attacker can abuse an XPath Transform to extract any local .xml files in a RetrievalMethod element.

5) SQL injection (CVE-ID: CVE-2022-23305)

The vulnerability allows a remote attacker to execute arbitrary SQL queries in database.

The vulnerability exists due to insufficient sanitization of user-supplied data in the JDBCAppender. A remote attacker can send a specially crafted request to the affected application and execute arbitrary SQL commands within the application database.

Note, a non-default configuration with enabled JDBCAppender is required to exploit the vulnerability.
