CVE-2024-27093 in minder
Summary
by MITRE • 02/27/2024
Minder is a Software Supply Chain Security Platform. In version 0.0.31 and earlier, it is possible for an attacker to register a repository with a invalid or differing upstream ID, which causes Minder to report the repository as registered, but not remediate any future changes which conflict with policy (because the webhooks for the repo do not match any known repository in the database). When attempting to register a repo with a different repo ID, the registered provider must have admin on the named repo, or a 404 error will result. Similarly, if the stored provider token does not have repo access, then the remediations will not apply successfully. Lastly, it appears that reconciliation actions do not execute against repos with this type of mismatch. This appears to primarily be a potential denial-of-service vulnerability. This vulnerability is patched in version 0.20240226.1425+ref.53868a8.

The vulnerability described in CVE-2024-27093 affects Minder, a Software Supply Chain Security Platform, specifically versions 0.0.31 and earlier. This security flaw stems from improper validation of repository registration processes where attackers can exploit a mismatch between the repository identifier provided during registration and the actual upstream repository identifier. The core technical issue manifests when an attacker registers a repository using an invalid or differing upstream ID, creating a discrepancy that prevents proper policy enforcement and remediation actions.
The vulnerability operates through a fundamental flaw in the platform's repository identification and webhook management system. When a repository is registered with a mismatched ID, the system reports successful registration while simultaneously failing to establish proper webhook connections that would enable policy enforcement. This creates a state where the platform believes the repository is registered and monitored, but in reality, it cannot detect or remediate policy violations. The system's reconciliation mechanisms fail to operate against repositories with these identifier mismatches, leaving them vulnerable to security issues that should be automatically addressed.
The operational impact of this vulnerability extends beyond simple denial-of-service conditions, representing a significant security weakness in the platform's access control and policy enforcement mechanisms. The vulnerability requires that the registered provider must have administrative privileges on the repository to avoid a 404 error, which creates an additional attack surface where malicious actors might attempt to escalate privileges or manipulate repository access. Furthermore, when stored provider tokens lack proper repository access permissions, remediation actions fail silently, creating false security assurances for administrators who believe their systems are protected. This vulnerability directly relates to CWE-284 (Improper Access Control) and CWE-345 (Insufficient Verification of Data Authenticity) as it allows unauthorized manipulation of repository state and policy enforcement.
The security implications of this vulnerability are particularly concerning for software supply chain security platforms where repository integrity is paramount. Attackers can exploit this weakness to create persistent blind spots in their security monitoring, allowing malicious code or policy violations to go undetected while the system appears to be functioning normally. The lack of proper reconciliation actions against mismatched repositories creates a scenario where the platform's security posture is artificially strengthened while actual vulnerabilities remain unaddressed. This vulnerability also intersects with ATT&CK technique T1078 (Valid Accounts) and T1566 (Phishing) as it could enable attackers to establish persistent access patterns that bypass normal security controls. The patch released in version 0.20240226.1425+ref.53868a8 addresses these issues through improved repository ID validation, enhanced webhook verification processes, and strengthened reconciliation mechanisms that ensure proper repository matching and access validation before enabling security enforcement actions.
