elasticsearch: remote code execution via Groovy sandbox bypass

The Groovy scripting engine in Elasticsearch before 1.3.8 and 1.4.x before 1.4.3 allows remote attackers to bypass the sandbox protection mechanism and execute arbitrary shell commands via a crafted script.

Improper Limitation of a Pathname to a Restricted Directory in Logstash Leading to Arbitrary File Write

Improper Limitation of a Pathname to a Restricted Directory (CWE-22) in Logstash can lead to arbitrary file write and potentially remote code execution via Relative Path Traversal (CAPEC-139). The archive extraction utilities used by Logstash do not properly validate file paths within compressed archives. An attacker who can serve a specially crafted archive to Logstash through a compromised or attacker-controlled update endpoint can write arbitrary files to the host filesystem with the privileges of the Logstash process. In certain configurations where automatic pipeline reloading is enabled, this can be escalated to remote code execution.

Incorrect Authorization in Kibana Fleet Leading to Information Disclosure

Incorrect Authorization (CWE-863) in Kibana can lead to cross-space information disclosure via Privilege Abuse (CAPEC-122). A user with Fleet agent management privileges in one Kibana space can retrieve Fleet Server policy details from other spaces through an internal enrollment endpoint. The endpoint bypasses space-scoped access controls by using an unscoped internal client, returning operational identifiers, policy names, management state, and infrastructure linkage details from spaces the user is not authorized to access.

Improper Input Validation in Kibana Leading to Denial of Service

Improper Input Validation (CWE-20) in the internal Content Connectors search endpoint in Kibana can lead Denial of Service via Input Data Manipulation (CAPEC-153)

Improper Input Validation in Metricbeat Leading to Denial of Service

Improper Validation of Array Index (CWE-129) exists in Metricbeat can allow an attacker to cause a Denial of Service through Input Data Manipulation (CAPEC-153) via specially crafted, malformed payloads sent to the Graphite server metricset or Zookeeper server metricset. Additionally, Improper Input Validation (CWE-20) exists in the Prometheus helper module that can allow an attacker to cause a Denial of Service through Input Data Manipulation (CAPEC-153) via specially crafted, malformed metric data.

Allocation of Resources Without Limits or Throttling in Kibana Leading to Excessive Allocation

Allocation of Resources Without Limits or Throttling (CWE-770) in Kibana Fleet can lead to Excessive Allocation (CAPEC-130) via a specially crafted request. This causes the application to perform redundant processing operations that continuously consume system resources until service degradation or complete unavailability occurs.

Allocation of Resources Without Limits or Throttling in Kibana Fleet

Allocation of Resources Without Limits or Throttling (CWE-770) in Kibana Fleet can lead to Excessive Allocation (CAPEC-130) via a specially crafted bulk retrieval request. This requires an attacker to have low-level privileges equivalent to the viewer role, which grants read access to agent policies. The crafted request can cause the application to perform redundant database retrieval operations that immediately consume memory until the server crashes and becomes unavailable to all users.

Improper Input Validation in Kibana Email Connector Leading to Excessive Allocation

Improper Input Validation (CWE-20) in Kibana's Email Connector can allow an attacker to cause an Excessive Allocation (CAPEC-130) through a specially crafted email address parameter. This requires an attacker to have authenticated access with view-level privileges sufficient to execute connector actions. The application attempts to process specially crafted email format, resulting in complete service unavailability for all users until manual restart is performed.

Improper Validation of Array Index in Packetbeat Leading to Overflow Buffers

Improper Validation of Array Index (CWE-129) in Packetbeat’s MongoDB protocol parser can allow an attacker to cause Overflow Buffers (CAPEC-100) through specially crafted network traffic. This requires an attacker to send a malformed payload to a monitored network interface where MongoDB protocol parsing is enabled.

External Control of File Name or Path and Server-Side Request Forgery (SSRF) in Kibana Google Gemini Connector

External Control of File Name or Path (CWE-73) combined with Server-Side Request Forgery (CWE-918) can allow an attacker to cause arbitrary file disclosure through a specially crafted credentials JSON payload in the Google Gemini connector configuration. This requires an attacker to have authenticated access with privileges sufficient to create or modify connectors (Alerts & Connectors: All). The server processes a configuration without proper validation, allowing for arbitrary network requests and for arbitrary file reads.

Improper Validation of Specified Quantity in Input in Kibana Leading to Denial of Service

Improper Validation of Specified Quantity in Input (CWE-1284) in Kibana can allow an authenticated attacker with view-only privileges to cause a Denial of Service via Input Data Manipulation (CAPEC-153). An attacker can send a specially crafted, malformed payload causing excessive resource consumption and resulting in Kibana becoming unresponsive or crashing.

Inefficient Regular Expression Complexity in Kibana Leading to Denial of Service

Inefficient Regular Expression Complexity (CWE-1333) in the AI Inference Anonymization Engine in Kibana can lead Denial of Service via Regular Expression Exponential Blowup (CAPEC-492).

Uncontrolled Resource Consumption in Kibana Leading to Denial of Service

Uncontrolled Resource Consumption (CWE-400) in the Timelion component in Kibana can lead Denial of Service via Input Data Manipulation (CAPEC-153)

Improper Neutralization of Special Elements Used in a Template Engine in Kibana Workflows Leading to Server-Side Request Forgery (SSRF)

Improper Neutralization of Special Elements Used in a Template Engine (CWE-1336) exists in Workflows in Kibana which could allow an attacker to read arbitrary files from the Kibana server filesystem, and perform Server-Side Request Forgery (SSRF) via Code Injection (CAPEC-242). This requires an authenticated user who has the workflowsManagement:executeWorkflow privilege.

Improper preservation of permissions in Elastic Defend on Windows hosts can lead to arbitrary files on the system being deleted by the Defend service running as SYSTEM. In some cases, this could result in local privilege escalation.

Logstash Improper Certificate Validation in TCP output

Improper certificate validation in Logstash's TCP output could lead to a man-in-the-middle (MitM) attack in “client” mode, as hostname verification in TCP output was not being performed when the ssl_verification_mode => full was set.

Kibana Insufficiently Protected Credentials in the CrowdStrike Connector

Insufficiently Protected Credentials in the Crowdstrike connector can lead to Crowdstrike credentials being leaked. A malicious user can access cached credentials from a Crowdstrike connector in another space by creating and running a Crowdstrike connector in a space to which they have access.

Beats Uncontrolled Search Path Element can lead to Local Privilege Escalation (LPE) when using the Windows Installer

An uncontrolled search path element vulnerability can lead to local privilege Escalation (LPE) via Insecure Directory Permissions. The vulnerability arises from improper handling of directory permissions. An attacker with local access may exploit this flaw to move and delete arbitrary files, potentially gaining SYSTEM privileges.

APM Server Uncontrolled Search Path Element can lead to Local Privilege Escalation (LPE) when using the Windows Installer

An uncontrolled search path element vulnerability can lead to local privilege Escalation (LPE) via Insecure Directory Permissions. The vulnerability arises from improper handling of directory permissions. An attacker with local access may exploit this flaw to move and delete arbitrary files, potentially gaining SYSTEM privileges.

Fleet Server sensitive information exposure via logs

An issue was identified in Fleet Server where Fleet policies that could contain sensitive information were logged on INFO and ERROR log levels. The nature of the sensitive information largely depends on the integrations enabled.
