CVE-2014-8682 in Gogs
Summary
by MITRE
Multiple SQL injection vulnerabilities in Gogs (aka Go Git Service) 0.3.1-9 through 0.5.x before 0.5.6.1105 Beta allow remote attackers to execute arbitrary SQL commands via the q parameter to (1) api/v1/repos/search, which is not properly handled in models/repo.go, or (2) api/v1/users/search, which is not properly handled in models/user.go.

The CVE-2014-8682 vulnerability represents a critical security flaw in the Gogs git service software that affects versions 0.3.1-9 through 0.5.x before 0.5.6.1105 Beta. This vulnerability manifests as multiple SQL injection vulnerabilities that enable remote attackers to execute arbitrary SQL commands against the underlying database system. The flaw specifically targets two API endpoints within the application's search functionality, making it particularly dangerous as it allows attackers to manipulate the database through legitimate application interfaces. The vulnerability stems from improper handling of user input parameters in the search functionality, creating a pathway for malicious SQL code execution that can compromise the entire database infrastructure.
The technical implementation of this vulnerability occurs in two distinct locations within the Gogs codebase, specifically in the models/repo.go file where the q parameter to api/v1/repos/search is not properly sanitized, and in models/user.go where the q parameter to api/v1/users/search suffers from the same inadequate input validation. These locations represent the core of the vulnerability as they handle search queries from external users without proper parameterization or input sanitization. The lack of proper input validation allows attackers to inject malicious SQL payloads directly through the search parameters, bypassing normal application security controls and potentially gaining unauthorized access to sensitive data, modifying database records, or even executing administrative commands on the database server itself. This vulnerability aligns with CWE-89 which specifically addresses SQL injection flaws in software applications.
The operational impact of CVE-2014-8682 extends far beyond simple data theft, as it provides attackers with complete database manipulation capabilities that can lead to full system compromise. Remote attackers can leverage this vulnerability to extract sensitive user information, including credentials and personal data, modify or delete repository information, and potentially escalate privileges within the application. The vulnerability's location within the search API endpoints makes it particularly dangerous as search functionality is typically accessed by multiple users and may not be properly monitored for malicious input. Attackers can craft specially crafted search queries that execute arbitrary SQL commands, potentially leading to data breaches, service disruption, and unauthorized access to the entire git repository management system. The impact is amplified by the fact that this vulnerability affects multiple versions of the software, meaning organizations running any of the affected versions are at risk.
Organizations affected by CVE-2014-8682 should immediately implement mitigations including updating to the patched version 0.5.6.1105 Beta or later, which addresses the SQL injection vulnerabilities through proper parameterization of database queries. Additionally, network-level firewalls should be configured to restrict access to the affected API endpoints where possible, and input validation should be strengthened at the application level to prevent malformed queries from reaching database systems. The vulnerability demonstrates the critical importance of proper input sanitization and parameterized queries in preventing SQL injection attacks, aligning with ATT&CK technique T1190 which covers SQL injection vulnerabilities. Organizations should also implement comprehensive logging and monitoring of API access patterns to detect potential exploitation attempts, and conduct thorough security assessments of all database interactions within the application to identify similar vulnerabilities that may exist in other parts of the codebase.
