CVE-2024-31455 in Minder
Summary
by MITRE • 04/09/2024
Minder by Stacklok is an open source software supply chain security platform. A refactoring in commit `5c381cf` added the ability to get GitHub repositories registered to a project without specifying a specific provider. Unfortunately, the SQL query for doing so was missing parenthesis, and would select a random repository. This issue is patched in pull request 2941. As a workaround, revert prior to `5c381cf`, or roll forward past `2eb94e7`.

The vulnerability identified as CVE-2024-31455 affects Minder by Stacklok, an open source software supply chain security platform designed to protect organizations against supply chain threats. This security flaw emerged from a refactoring operation in commit 5c381cf that introduced functionality to retrieve GitHub repositories associated with a project without requiring explicit provider specification. The vulnerability represents a critical authorization and data access control issue that could potentially allow unauthorized access to repository information within the platform's database.
The technical root cause of this vulnerability stems from a malformed SQL query that lacks proper parentheses in its construction. This syntactical error in the database access logic results in unpredictable query execution patterns that select random repository entries from the database rather than the intended specific repository data. The absence of proper query structure means that the system cannot reliably determine which repository records should be retrieved, creating a significant data integrity and access control flaw. This type of vulnerability falls under CWE-89 SQL Injection, specifically related to improper query construction and lack of input validation in database access operations.
The operational impact of this vulnerability extends beyond simple data retrieval issues as it could potentially enable attackers to access unauthorized repository information within the software supply chain platform. Given that Minder is designed to secure software supply chains, this flaw could compromise the integrity of the security monitoring capabilities by allowing unauthorized access to repository data that should be restricted to authorized users or projects. The vulnerability essentially creates a backdoor path for information disclosure that undermines the platform's core security objectives and could lead to more severe consequences if combined with other attack vectors.
Mitigation strategies for this vulnerability involve either reverting to a previous stable version before the problematic commit 5c381cf or upgrading to a patched version that follows commit 2eb94e7. Organizations using Minder should immediately assess their current deployment status and implement the appropriate remediation path as specified in the patch details. The fix addresses the core SQL query construction issue by properly implementing the necessary parentheses to ensure deterministic repository selection. Security teams should also conduct comprehensive audits of their software supply chain monitoring systems to identify any potential exploitation attempts that may have occurred during the vulnerable period. This vulnerability highlights the critical importance of proper database query construction and input validation in security-critical applications, aligning with ATT&CK technique T1213 Data from Information Repositories which focuses on accessing data repositories through improper query handling and access control mechanisms.
