Quarterly Report: Incident Response Trends in Q3 2022

Ransomware and pre-ransomware engagements make up 40 percent of threats seen this quarter By Caitlin Huey. For the first time since compiling these reports, Cisco Talos Incident Response saw an equal number of ransomware and pre-ransomware engagements, making up nearly 40 percent of threats this quarter.   It can be difficult to determine what constitutes a pre-ransomware attack if ransomware never executes and encryption does not take place. However, Talos IR assesses that the combination of Cobalt Strike and credential-harvesting tools like Mimikatz, paired with enumeration and discovery techniques, indicates a high likelihood that ransomware is the final objective. This quarter featured a variety of publicly available tools and scripts hosted on GitHub repositories or other third-party websites to support operations across multiple stages of the attack lifecycle. This activity coincides with a general increase in the use of other dual-use tools, such as the legitimate red-teaming ...

CVE-2022-34917: Apache Kafka

A security vulnerability has been identified in Apache Kafka. It affects all releases since 2.8.0. The vulnerability allows malicious unauthenticated clients to allocate large amounts of memory on brokers. This can lead to brokers hitting OutOfMemoryException and causing denial of service. Example scenarios: - Kafka cluster without authentication: Any clients able to establish a network connection to a broker can trigger the issue. - Kafka cluster with SASL authentication: Any clients able to establish a network connection to a broker, without the need for valid SASL credentials, can trigger the issue. - Kafka cluster with TLS authentication: Only clients able to successfully authenticate via TLS can trigger the issue. We advise the users to upgrade the Kafka installations to one of the 3.2.3, 3.1.2, 3.0.2, 2.8.2 versions.

CVE-2022-32552: Security Advisory for security-bundle-2022-04-04

Pure Storage FlashArray products running Purity//FA 6.2.0 - 6.2.3, 6.1.0 - 6.1.12, 6.0.0 - 6.0.8, 5.3.0 - 5.3.17, 5.2.x and prior Purity//FA releases, and Pure Storage FlashBlade products running Purity//FB 3.3.0, 3.2.0 - 3.2.4, 3.1.0 - 3.1.12, 3.0.x and prior Purity//FB releases are vulnerable to a privilege escalation via the manipulation of Python environment variables which can be exploited by a logged-in user to escape a restricted shell to an unrestricted shell with root privileges. No other Pure Storage products or services are affected. Remediation is available from Pure Storage via a self-serve “opt-in” patch, manual patch application or a software upgrade to an unaffected version of Purity software.

CVE-2022-29855: Security Advisories

Mitel 6800 and 6900 Series SIP phone devices through 2022-04-27 have "undocumented functionality." A vulnerability in Mitel 6800 Series and 6900 Series SIP phones excluding 6970, versions 5.1 SP8 (5.1.0.8016) and earlier, and 6.0 (6.0.0.368) through 6.1 HF4 (6.1.0.165), could allow a unauthenticated attacker with physical access to the phone to gain root access due to insufficient access control for test functionality during system startup. A successful exploit could allow access to sensitive information and code execution.

CVE-2021-4104: Red Hat Customer Portal - Access to 24x7 support and knowledge

JMSAppender in Log4j 1.2 is vulnerable to deserialization of untrusted data 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 in a similar fashion to CVE-2021-44228. Note this issue only affects Log4j 1.2 when specifically configured to use JMSAppender, which is not the default. Apache Log4j 1.2 reached end of life in August 2015. Users should upgrade to Log4j 2 as it addresses numerous other issues from the previous versions.

CVE-2021-44228: Log4j – Apache Log4j Security Vulnerabilities

Apache Log4j2 2.0-beta9 through 2.15.0 (excluding security releases 2.12.2, 2.12.3, and 2.3.1) JNDI features used in configuration, log messages, and parameters do not protect against attacker controlled LDAP and other JNDI related endpoints. An attacker who can control log messages or log message parameters can execute arbitrary code loaded from LDAP servers when message lookup substitution is enabled. From log4j 2.15.0, this behavior has been disabled by default. From version 2.16.0 (along with 2.12.2, 2.12.3, and 2.3.1), this functionality has been completely removed. Note that this vulnerability is specific to log4j-core and does not affect log4net, log4cxx, or other Apache Logging Services projects.
