CVE-2024-28155 in AppSpider Plugin
Summary
by MITRE • 03/06/2024
Jenkins AppSpider Plugin 1.0.16 and earlier does not perform permission checks in several HTTP endpoints, allowing attackers with Overall/Read permission to obtain information about available scan config names, engine group names, and client names.

The vulnerability identified as CVE-2024-28155 affects the Jenkins AppSpider Plugin version 1.0.16 and earlier, presenting a critical authorization flaw that undermines the security posture of Jenkins environments. This issue stems from insufficient permission validation within multiple HTTP endpoints exposed by the plugin, creating a pathway for unauthorized information disclosure that can significantly impact the security of automated testing and vulnerability assessment processes. The vulnerability specifically targets the AppSpider plugin which integrates security scanning capabilities into Jenkins CI/CD pipelines, making it particularly concerning for organizations that rely on automated security testing within their development workflows.
The technical flaw manifests as a lack of proper access control validation in the plugin's HTTP endpoints, allowing attackers with minimal Overall/Read permission to extract sensitive information about the security scanning infrastructure. This includes enumeration of available scan configuration names, engine group identifiers, and client names that are typically restricted to administrators or users with higher privileges. The vulnerability operates at the application layer, exploiting the absence of proper authorization checks that should validate user permissions before exposing internal system information. This type of information disclosure vulnerability is classified as CWE-284 Access Control Issues, specifically representing inadequate access control mechanisms that permit unauthorized access to sensitive data.
The operational impact of this vulnerability extends beyond simple information disclosure, as it enables attackers to gather intelligence that can facilitate more sophisticated attacks against the Jenkins environment and associated security scanning infrastructure. An attacker who gains Overall/Read permission through other means can leverage this vulnerability to map the security scanning landscape, identifying potential targets and configurations that may be exploited in subsequent attacks. This reconnaissance capability aligns with ATT&CK technique T1087.001 Account Discovery and T1069.001 Permission Groups Discovery, as it allows adversaries to understand the access control structure and available resources within the security scanning infrastructure. The information obtained could be used to plan targeted attacks against specific scan configurations or engine groups that might contain known vulnerabilities or weak configurations.
Organizations should immediately implement mitigations including updating to the latest version of the Jenkins AppSpider Plugin where the permission checks have been properly implemented. Additionally, administrators should review and enforce strict access controls within their Jenkins instances, ensuring that users with Overall/Read permission cannot access sensitive plugin information. Network segmentation and firewall rules should be implemented to restrict access to Jenkins plugin endpoints, while monitoring should be enabled to detect unusual access patterns or enumeration attempts. The vulnerability demonstrates the critical importance of implementing proper authorization checks in all application components, particularly those that interface with security tools and sensitive system information, as highlighted by security best practices outlined in the OWASP Top Ten and NIST Cybersecurity Framework.
