Description

This security bulletin contains information about 7 secuirty vulnerabilities.


1) 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}}}}


2) 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.


3) Buffer overflow (CVE-ID: CVE-2021-39275)

The vulnerability allows a remote attacker to execute arbitrary code on the target system or perform a denial of service attack.

The vulnerability exists due to a boundary error within the ap_escape_quotes()  function. A remote attacker can send a specially crafted request to the web server, trigger memory corruption and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system but requires that the Apache module passes untrusted data to the affected function.

According to vendor, No included modules pass untrusted data to these functions


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) 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.


6) Resource exhaustion (CVE-ID: CVE-2021-38951)

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

The vulnerability exists due to application does not properly control consumption of internal resources. A remote attacker can send a specially crafted request to the web server, consume all available CPU resources and perform a denial of service (DoS) attack.


7) Information disclosure (CVE-ID: CVE-2021-29842)

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to excessive data output, when the WebSphere Application Server is configured with a federated repository. A remote attacker can gain unauthorized access to sensitive information on the system.
