Description
This security bulletin contains information about 4 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) 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,
$${ctx:loginId}) or a Thread Context Map pattern (%X, %mdc, or %MDC) can
pass malicious data using a JNDI Lookup pattern and perform a denial of
service (DoS) attack, exfiltrate data or execute arbitrary code.
Later discovery demonstrates a remote code execution on macOS but no other tested environments.
3) Infinite loop (CVE-ID: CVE-2021-45105)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to infinite loop within the StrSubstitutor class. A remote attacker can pass specially crafted input to the application, consume all available system resources and cause denial of service conditions.
Payload example: ${${::-${::-$${::-j}}}}
4) 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.
