Summary

CVE-2016-20092 is a high-severity Unquoted Search Path or Element (CWE-428) vulnerability in Netdrive (inferred from references). Its CVSS base score is 8.5 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Path Interception (T1034); ranked at the 6th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SA-15 (Development Process, Standards, and Tools) — see the control section below for these in your framework.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

Developer testing and evaluation can discover unquoted search paths through static analysis or dynamic test cases.

Documented development standards and tools can mandate proper quoting and escaping of path elements.

Engineering principles can require safe construction and quoting of search paths and command elements.
