SQL injection vulnerability in Crocus v.1.3.44 allows a remote attacker to escalate privileges via the DeviceInfoMapper.xml file

AnalysisAI

Privilege escalation via SQL injection in Crocus version 1.3.44 allows remote attackers to manipulate backend database queries through the DeviceInfoMapper.xml data-access layer, yielding full read/write control over application data. The flaw carries a CVSS 9.8 (network, no authentication) rating, and publicly available exploit code exists in a GitHub write-up, though it is not listed in CISA KEV and its EPSS exploitation probability is low (0.20%, 10th percentile).

Technical ContextAI

The vulnerability is a classic CWE-89 SQL injection rooted in the DeviceInfoMapper.xml file - a naming and file convention strongly associated with MyBatis/iBatis SQL mapper definitions used by Java (typically Spring) applications. In MyBatis XML mappers, dynamic SQL built with unsafe string substitution (the '${}' token) rather than the parameterized '#{}' placeholder concatenates attacker-controlled input directly into query text, allowing query structure to be altered. Because the injection reportedly enables privilege escalation, the affected query likely governs authorization, role, or device-ownership logic. The CPE provided by the source is a placeholder ('cpe:2.3:a:n/a:n/a:*') and does not identify a canonical vendor/product, limiting automated matching.

RemediationAI

No vendor-released patch identified at time of analysis, and no fixed version is published in the available data, so upgrade guidance cannot cite an exact release. As primary compensating controls: parameterize the vulnerable query by replacing any MyBatis '${}' string substitution in DeviceInfoMapper.xml with the safe '#{}' bound-parameter syntax, which is the definitive code-level fix (side effect: requires source access and a rebuild). Where code changes are not immediately possible, place the affected endpoint behind a web application firewall with SQLi signatures tuned to the device-info parameters (trade-off: signature evasion is possible and may cause false positives), restrict network access to the device-management interface to trusted management networks or a VPN (trade-off: reduces legitimate remote access), and enforce least-privilege on the application's database account so a successful injection cannot alter schema or escalate DB roles (trade-off: may break features that rely on broad DB grants). Monitor the referenced GitHub advisory (https://github.com/Y4y17/CVE/blob/main/Crocus/SQL%20Injection-1.md) and the vendor for a patched release.
