Security Bulletin

This security bulletin contains information about 3 vulnerabilities.

1) SQL injection

EUVDB-ID: #VU59691

Risk: Medium

CVSSv3.1:

CVE-ID: CVE-2022-23305

CWE-ID: CWE-89 - Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')

Exploit availability: No

Description

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.

Mitigation

Install updates from vendor's website.

2) Deserialization of Untrusted Data

EUVDB-ID: #VU59693

Risk: High

CVSSv3.1:

CVE-ID: CVE-2022-23307,CVE-2020-9493

CWE-ID: CWE-502 - Deserialization of Untrusted Data

Exploit availability: No

Description

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.

Mitigation

Install updates from vendor's website.

EUVDB-ID: #VU59692

Risk: High

CVSSv3.1:

CVE-ID: CVE-2022-23302

CWE-ID: CWE-502 - Deserialization of Untrusted Data

Exploit availability: No

Description

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.

Mitigation

Install updates from vendor's website.
