Description
This security bulletin contains information about 9 secuirty vulnerabilities.
1) Deserialization of Untrusted Data (CVE-ID: CVE-2019-17571)
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 within the SocketServer class in Log4j. A remote attacker can pass specially crafted data to the application and execute arbitrary code on the target system, if these is a deserialization gadget listening to untrusted network traffic for log data.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
2) 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.
3) 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.
4) 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.
5) Improper Certificate Validation (CVE-ID: CVE-2020-9488)
The vulnerability allows a remote attacker to perform man-in-the-middle attack.
The vulnerability exists due to the Apache Log4j SMTP appender does not validate SSL certificates. A remote attacker can perform a MitM attack, intercept and decrypt network traffic.
6) Input validation error (CVE-ID: CVE-2023-24329)
The vulnerability allows a remote attacker to bypass implemented filters.
The vulnerability exists due to insufficient validation of URLs that start with blank characters within urllib.parse component of Python. A remote attacker can pass specially crafted URL to bypass existing filters.
7) 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.
8) Authorization bypass through user-controlled key (CVE-ID: CVE-2022-34352)
The vulnerability allows a remote user to gain access to sensitive information.
The vulnerability exists due to missing permissions checks. A remote delegated Admin tenant user with a specific domain security profile assigned can see data from other domains.
9) Improper access control (CVE-ID: CVE-2023-43041)
The vulnerability allows a remote user to gain unauthorized access to otherwise restricted functionality.
The vulnerability exists due to improper access restrictions. A delegated Admin tenant user with a specific domain security profile assigned to see data from other domains.
