![]() The initial fixes in CVE-2022-30126 and CVE-2022-30973 for regexes in the StandardsExtractingContentHandler were insufficient, and we found a separate, new regex DoS in a different regex in the StandardsExtractingContentHandler. This affects Apache Spark versions 3.0.3 and earlier, versions 3.1.1 to 3.1.2, and versions 3.2.0 to 3.2.1. This will result in arbitrary shell command execution as the user Spark is currently running as. A malicious user might then be able to reach a permission check function that will ultimately build a Unix shell command based on their input, and execute it. If ACLs are enabled, a code path in HttpSecurityFilter can allow someone to perform impersonation by providing an arbitrary user name. With an authentication filter, this checks whether a user has access permissions to view or modify the application. The Apache Spark UI offers the possibility to enable ACLs via the configuration option. A local user could cause the hotpatch script to execute a binary with elevated privileges by running a custom java process that performs exec() of an SUID binary after the hotpatch has observed the process path and before it has observed its effective user ID. To do so, it iterates through all running Java processes, performs several checks, and executes the Java virtual machine with the same permissions and capabilities as the running process to load the hotpatch. This Hotpatch package is not a replacement for updating to a log4j version that mitigates CVE-2021-44228 or CVE-2021-45046 it provides a temporary mitigation to CVE-2021-44228 by hotpatching the local Java virtual machines. Versions of the Amazon AWS Apache Log4j hotpatch package before log4j-cve-2021-44228-hotpatch-1.3.5 are affected by a race condition that could lead to a local privilege escalation. ![]() Users are recommended to upgrade to Apache Commons Configuration 2.8.0, which disables the problematic interpolators by default. ![]() These lookups are: - "script" - execute expressions using the JVM script execution engine (javax.script) - "dns" - resolve dns records - "url" - load values from urls, including from remote servers Applications using the interpolation defaults in the affected versions may be vulnerable to remote code execution or unintentional contact with remote servers if untrusted configuration values are used. Starting with version 2.4 and continuing through 2.7, the set of default Lookup instances included interpolators that could result in arbitrary code execution or contact with remote servers. The standard format for interpolation is "$", where "prefix" is used to locate an instance of 2.interpol.Lookup that performs the interpolation. In Apache Tomcat 10.1.0-M1 to 10.1.0-M16, 10.0.0-M1 to 10.0.22, 9.0.30 to 9.0.64 and 8.5.50 to 8.5.81 the Form authentication example in the examples web application displayed user provided data without filtering, exposing a XSS vulnerability.Īpache Commons Configuration performs variable interpolation, allowing properties to be dynamically evaluated and expanded. ![]() The SAML 2.0 messages constructed during the authentication flow in Apache CloudStack are XML-based and the XML data is parsed by various standard libraries that are now understood to be vulnerable to XXE injection attacks such as arbitrary file reading, possible denial of service, server-side request forgery (SSRF) on the CloudStack management server. When the SAML 2.0 plugin is enabled in affected versions of Apache CloudStack could potentially allow the exploitation of XXE vulnerabilities. This plugin is not enabled by default and the attacker would require that this plugin be enabled to exploit the vulnerability. The vulnerability will cause NodeJS services that has this agent installed to be unavailable if the OAP is unhealthy and NodeJS agent can't establish the connection.Īpache CloudStack version 4.5.0 and later has a SAML 2.0 authentication Service Provider plugin which is found to be vulnerable to XML external entity (XXE) injection. A vulnerability in Apache SkyWalking NodeJS Agent prior to 0.5.1.
