Summary

CVE-2019-25308 is a high-severity Unquoted Search Path or Element (CWE-428) vulnerability in Mikogo Mikogo. Its CVSS base score is 8.5 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Path Interception (T1034); ranked at the 12th 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.

CVE-2019-25308 is an unquoted service path vulnerability in the Mikogo-Service Windows service configuration within Mikogo version 5.2.2.150317. This issue, mapped to CWE-428, allows attackers to exploit the unquoted path by placing executable files in specific locations, enabling code injection and execution with LocalSystem privileges. The vulnerability carries a CVSS v3.1 base score of 7.8 (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H).

A local attacker with low privileges can exploit this vulnerability with minimal complexity and no user interaction required. By dropping malicious executables in the expected unquoted path directories, the attacker tricks the service into executing their code upon startup or restart, achieving high-impact confidentiality, integrity, and availability effects, including potential full system compromise under LocalSystem context.

Advisories, including the Vulncheck advisory on the Mikogo-Service unquoted service path and an Exploit-DB entry (47510) demonstrating the exploit, highlight the configuration flaw but do not specify patches or vendor mitigations in the available references. A Tucows preview page for Mikogo provides additional software context. Security practitioners should verify service path configurations and consider removing or updating legacy Mikogo installations.

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.
