SB2022051250 - Multiple vulnerabilities in Crypto Hardware Initialization and Maintenance (CHIM) as shipped with IBM Common Cryptographic Architecture (CCA)

Description

This security bulletin contains information about 5 secuirty vulnerabilities.

1) Deserialization of Untrusted Data (CVE-ID: CVE-2021-4104)

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

The vulnerability exists due to insecure input validation when processing serialized data in JMSAppender, when the attacker has write access to the Log4j configuration. The attacker can provide TopicBindingName and TopicConnectionFactoryBindingName configurations causing JMSAppender to perform JNDI requests that result in remote code execution.

Note this issue only affects Log4j 1.2 when specifically configured to use JMSAppender, which is not the default.

2) Deserialization of Untrusted Data (CVE-ID: CVE-2022-23302)

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

The vulnerability exists due to insecure input validation when processing serialized data in JMSSink. A remote attacker can provide a TopicConnectionFactoryBindingName configuration causing JMSSink to perform JNDI requests and execute arbitrary code on the target system.

Note, a non-default configuration with support for JMSSink is required to exploit this vulnerability.

3) 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.

4) Deserialization of Untrusted Data (CVE-ID: CVE-2020-9493)

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

The vulnerability exists due to insecure input validation when processing serialized data. A remote attacker can pass specially crafted data 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) Use of a broken or risky cryptographic algorithm (CVE-ID: CVE-2022-23303)

The vulnerability allows a remote attacker to gain access to sensitive information on the target system.

The vulnerability exists due to the implementations of SAE are vulnerable to side-channel attacks as a result of cache access patterns. A remote attacker with ability to install and execute applications can crack weak passwords when memory access patterns are visible in a shared cache.

Note, this vulnerability exists due to incomplete fix for #VU23959 (CVE-2019-9494).

Remediation
