Am I affected?
Debian, Ubuntu or Red Hat sometimes backport a fix without changing the upstream version number: such a version reads « to verify », never « affected ».With a domain, we read the version its public headers and pages expose. A distribution build can carry the fix under an older number.
Description
GE Gas Power ToolBoxST Version v04.07.05C suffers from an XML external entity (XXE) vulnerability using the DTD parameter entities technique that could result in disclosure and retrieval of arbitrary data on the affected node via an out-of-band (OOB) attack. The vulnerability is triggered when input passed to the XML parser is not sanitized while parsing the XML project/template file.
