CVE-2026-42213: CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') in anzory SolidCAM-GPPL-IDE
SolidCAM-GPPL-IDE is an unofficial, independently developed extension, Postprocessor IDE for SolidCAM. From version 1.0.0 to before version 1.0.2, the inc "filename" directive in GPPL postprocessor files is resolved by GpplDocumentLinkHandler into a clickable link (VS Code textDocument/documentLink). The handler accepted arbitrary paths — absolute, relative with parent-directory segments (..\..\..\), UNC (\\server\share\), and arbitrary subfolders — and called File.Exists on each to decide whether to render the link. Two distinct attack surfaces resulted: information disclosure via File.Exists probing and NTLM hash leak via UNC path probing. This issue has been patched in version 1.0.2.
AI Analysis
Technical Summary
The vulnerability in SolidCAM-GPPL-IDE versions 1.0.0 to before 1.0.2 involves the inc "filename" directive in GPPL postprocessor files, which is resolved by GpplDocumentLinkHandler into clickable links. The handler accepted arbitrary paths without proper restriction, including absolute paths, relative paths with '..' segments, and UNC paths. It used File.Exists to check these paths, enabling attackers to probe for file existence (information disclosure) and potentially leak NTLM hashes by triggering UNC path requests. This path traversal and related issues were patched in version 1.0.2.
Potential Impact
Exploitation allows attackers to perform information disclosure by probing arbitrary file paths on the host system and potentially leak NTLM authentication hashes via UNC path probing. This could lead to further reconnaissance or lateral movement in a network environment. The vulnerability does not require privileges and can be triggered with user interaction. The CVSS 4.0 base score is 5.1, indicating medium severity.
Mitigation Recommendations
Upgrade SolidCAM-GPPL-IDE to version 1.0.2 or later, where this vulnerability has been patched. No other specific mitigations are indicated. Patch status is confirmed by the vendor's versioning information.
