CVE-2022-45132: n/a in n/a
In Linaro Automated Validation Architecture (LAVA) before 2022.11.1, remote code execution can be achieved through user-submitted Jinja2 template. The REST API endpoint for validating device configuration files in lava-server loads input as a Jinja2 template in a way that can be used to trigger remote code execution in the LAVA server.
AI Analysis
Technical Summary
CVE-2022-45132 is a critical remote code execution (RCE) vulnerability affecting versions of the Linaro Automated Validation Architecture (LAVA) prior to 2022.11.1. LAVA is a framework used primarily for automated testing and validation of embedded devices. The vulnerability arises from improper handling of user-submitted Jinja2 templates within the lava-server component, specifically at the REST API endpoint responsible for validating device configuration files. The endpoint loads input as a Jinja2 template without adequate sanitization or restrictions, allowing an attacker to craft malicious templates that execute arbitrary code on the server hosting LAVA. This vulnerability is classified under CWE-94 (Improper Control of Generation of Code), indicating that untrusted input is used to generate code that is then executed. The CVSS v3.1 base score is 9.8, reflecting the high severity due to the vulnerability's network attack vector, no required privileges or user interaction, and its impact on confidentiality, integrity, and availability. Exploitation can lead to full system compromise of the LAVA server, enabling attackers to execute arbitrary commands, potentially pivot within the network, exfiltrate sensitive data, or disrupt automated testing workflows. No public exploits are currently known in the wild, but the critical nature and ease of exploitation make it a significant threat to organizations using LAVA for device validation.
Potential Impact
For European organizations, the impact of CVE-2022-45132 can be substantial, especially those involved in embedded systems development, telecommunications, automotive, and IoT sectors where LAVA is commonly used for device testing and validation. Successful exploitation could lead to unauthorized access to internal networks, compromise of intellectual property related to device configurations and testing processes, and disruption of continuous integration/continuous deployment (CI/CD) pipelines. This can delay product development cycles and introduce risks of deploying compromised or malfunctioning devices. Additionally, attackers could leverage the compromised LAVA server as a foothold for lateral movement within corporate networks, potentially impacting other critical infrastructure. Given the criticality of the vulnerability and the sensitive nature of the environments where LAVA is deployed, the threat poses a significant risk to confidentiality, integrity, and availability of organizational assets.
Mitigation Recommendations
To mitigate CVE-2022-45132, organizations should immediately upgrade LAVA to version 2022.11.1 or later, where the vulnerability has been addressed. If upgrading is not immediately feasible, organizations should restrict access to the lava-server REST API endpoint by implementing network segmentation and firewall rules to limit exposure to trusted users and systems only. Additionally, input validation and sanitization should be enforced on any user-submitted templates to prevent malicious code execution. Monitoring and logging of API usage should be enhanced to detect anomalous or suspicious template submissions. Employing application-layer firewalls or runtime application self-protection (RASP) solutions can provide additional layers of defense. Finally, organizations should conduct thorough audits of their LAVA deployments and related infrastructure to identify any signs of compromise and ensure that incident response plans are updated to address potential exploitation scenarios.
