The vulnerability identified as CVE-2018-6382 affects MantisBT version 2.10.0 and represents a critical SQL injection flaw that enables local attackers to execute malicious database commands. This vulnerability specifically resides within the vendor/adodb/adodb-php/server.php component of the application, where the sql parameter fails to properly sanitize user input before processing database queries. The attack vector requires local system access, meaning an attacker must already have compromised credentials or physical access to the target machine to exploit this weakness. The vulnerability is particularly concerning because it operates through a request directed to the loopback interface at 127.0.0.1, indicating that the malicious input is processed locally rather than through network-facing components.
The technical implementation of this vulnerability stems from inadequate input validation and sanitization within the ADOdb PHP library component that MantisBT utilizes for database operations. When a local user submits a request containing malicious SQL code through the sql parameter, the application fails to properly escape or filter special characters that could alter the intended database query structure. This lack of proper input sanitization creates an environment where attacker-controlled SQL statements can be injected and executed with the privileges of the web application's database user. The vulnerability aligns with CWE-89, which specifically addresses SQL injection flaws, and demonstrates how improper data validation can lead to unauthorized database access and potential data compromise. The use of the loopback interface as the attack target suggests that this vulnerability may be exploited through local service interactions or through compromised web server processes that can make requests to localhost.
The operational impact of CVE-2018-6382 extends beyond simple data theft, as successful exploitation could enable attackers to modify, delete, or extract sensitive information from the MantisBT database. This includes user credentials, issue tracking data, project information, and potentially system configuration details that could further aid in lateral movement within the network. The local privilege requirement does not diminish the severity of this vulnerability, as local access often implies that an attacker has already compromised the system through other means, making this a dangerous escalation vector. The vulnerability affects organizations that rely on MantisBT for issue tracking and project management, potentially exposing sensitive business data and compromising the integrity of their development processes. This weakness could also facilitate more sophisticated attacks by providing attackers with database access that could be leveraged for privilege escalation or to establish persistent access points.
Organizations should immediately apply the vendor-provided patch or upgrade to a version of MantisBT that addresses this vulnerability. The mitigation strategy should include comprehensive input validation for all database parameters and implementation of proper parameterized queries to prevent SQL injection attacks. Security teams should also conduct thorough audits of the MantisBT installation to identify any other potential injection points and ensure that all components are updated to their latest secure versions. Network segmentation and access controls should be reviewed to minimize the impact of local compromise, while monitoring systems should be configured to detect unusual database access patterns that could indicate exploitation attempts. This vulnerability demonstrates the importance of maintaining up-to-date third-party libraries and implementing robust security controls throughout the entire application stack, as weaknesses in supporting components can compromise the security of the entire system. The ATT&CK framework categorizes this vulnerability under the T1071.004 technique for application layer protocol tunneling and T1046 for network service discovery, indicating that exploitation could lead to broader reconnaissance and lateral movement capabilities for threat actors.
