Description

This security bulletin contains information about 6 secuirty vulnerabilities.


1) 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.


2) Infinite loop (CVE-ID: CVE-2021-45105)

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

The vulnerability exists due to infinite loop within the StrSubstitutor class. A remote attacker can pass specially crafted input to the application, consume all available system resources and cause denial of service conditions.

Payload example: ${${::-${::-$${::-j}}}}


3) 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.


4) Code Injection (CVE-ID: CVE-2021-45046)

The vulnerability allows a remote attacker to compromise the affected system.

The vulnerability exists due to incomplete patch in Apache Log4j 2.15.0 for a code injection vulnerability #VU58816 (CVE-2021-44228) in certain non-default configurations. A remote attacker with control over Thread Context Map (MDC) input data when the logging configuration uses a non-default Pattern Layout with either a Context Lookup (for example, $${ctx:loginId}) or a Thread Context Map pattern (%X, %mdc, or %MDC) can pass malicious data using a JNDI Lookup pattern and perform a denial of service (DoS) attack, exfiltrate data or execute arbitrary code.

Later discovery demonstrates a remote code execution on macOS but no other tested environments.


5) Code Injection (CVE-ID: CVE-2021-44228)

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

The vulnerability exists due to improper input validation when processing LDAP requests. A remote attacker can send a specially crafted request to the application and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

Note, we are aware of attackers exploiting the vulnerability in the wild.


6) 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.
