The manifest contains package URLs and SHA-256 hashes but is not digitally signed, so its authenticity relies solely on the underlying TLS channel. In affected versions, TLS certificate validation can be disabled when a proxy is configured, allowing an attacker who can intercept network traffic to supply a malicious update manifest and corresponding package with a matching hash. This can cause the client to download and install a tampered update, resulting in arbitrary code execution with the privileges of the GoSign Desktop user on Windows and macOS, or with elevated privileges on some Linux deployments. A local attacker who can modify proxy settings may also abuse this behavior to escalate privileges by forcing installation of a crafted update."}], "lastModified": "2025-12-31T02:19:33.927", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:infocert:gosign:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "D2FBEC2B-9A8C-4C70-A2D2-232DB7D8D059", "versionEndExcluding": "2.4.1"}], "operator": "OR"}]}], "sourceIdentifier": "disclosure@vulncheck.com"}
