Exposure of sensitive information in exceptions in ClickHouse's clickhouse-r2dbc, com.clickhouse:clickhouse-jdbc, and com.clickhouse:clickhouse-client versions less than 0.4.6 allows unauthorized users to gain access to client certificate passwords via client exception logs. This occurs when 'sslkey' is specified and an exception, such as a ClickHouseException or SQLException, is thrown during database operations; the certificate password is then included in the logged exception message.

This Metasploit module exploit takes advantage of the StringSubstitutor interpolator class, which is included in the Commons Text library. A default interpolator allows for string lookups that can lead to remote code execution. This is due to a logic flaw that makes the script, dns and url lookup keys interpolated by default, as opposed to what it should be, according to the documentation of the StringLookupFactory class. Those keys allow an attacker to execute arbitrary code via lookups primarily using the script key. In order to exploit the vulnerabilities, the following requirements must be met: Run a version of Apache Commons Text from version 1.5 to 1.9, use the StringSubstitutor interpolator, and the target should run JDK versions prior to 15.

Red Hat Security Advisory 2024-0266-03 - An update for java-11-openjdk is now available for Red Hat Enterprise Linux 8, Red Hat Enterprise Linux 8.8 Extended Update Support, Red Hat Enterprise Linux 9, and Red Hat Enterprise Linux 9.2 Extended Update Support. Issues addressed include code execution and out of bounds access vulnerabilities.

Many organizations require Encryption In Transit (EIT), specifying that all network traffic should be encrypted between systems. Within a Red Hat OpenShift cluster, Red Hat OpenShift Service Mesh can implement Mutual Transport Layer Security (mTLS) between pods. This process encrypts all pod-to-pod traffic, satisfying the EIT requirement.This article covers a simple application that connects to an AMQ broker and leverages Service Mesh to encrypt all communications to and from the AMQ broker.The applicationThe application is a basic producer/consumer program based on the Camel On Quarkus framew

An issue was discovered in Contiki-NG tinyDTLS versions through 2018-08-30. A buffer over-read exists in the dtls_sha256_update function. This bug allows remote attackers to cause a denial of service (crash) and possibly read sensitive information by sending a malformed packet with an over-large fragment length field, due to servers incorrectly handling malformed packets.

An issue was discovered in Contiki-NG tinyDTLS versions through 2018-08-30. DTLS servers allow remote attackers to reuse the same epoch number within two times the TCP maximum segment lifetime, which is prohibited in RFC6347. This vulnerability allows remote attackers to obtain sensitive application (data of connected clients).

An issue was discovered in Contiki-NG tinyDTLS versions through 2018-08-30. An assertion failure in check_certificate_request() causes the server to exit unexpectedly, resulting in a denial of service.

An issue was discovered in Contiki-NG tinyDTLS versions through 2018-08-30. Incorrect handling of over-large packets in dtls_ccm_decrypt_message() causes a buffer over-read that can expose sensitive information.

An issue was discovered in Contiki-NG tinyDTLS versions through 2018-08-30. An infinite loop bug exists during the handling of a ClientHello handshake message. This bug allows remote attackers to cause a denial of service by sending a malformed ClientHello handshake message with an odd length of cipher suites, which triggers an infinite loop (consuming all resources) and a buffer over-read that can disclose sensitive information.

An issue was discovered in Contiki-NG tinyDTLS versions through 2018-08-30. DTLS servers mishandle the early use of a large epoch number. This vulnerability allows remote attackers to cause a denial of service and false-positive packet drops.
