DescriptionCVE.org

Snipe-IT is an IT asset management application. In Snipe-IT master-branch builds after 8.6.3 (the code was never included in a tagged release), SettingsController::downloadLocationScopingReport streams the FMCS location-scoping mismatch report (GET /admin/settings/location-scoping-report.csv) through a bare fputcsv() call without applying League\Csv\EscapeFormula, unlike the other CSV exports which honor config('app.escape_formulas'). An authenticated user with ordinary create/edit rights can place a spreadsheet formula in free-text fields that appear in the report (item name, asset tag, serial, item or location company name, location name) and arrange for the record to be FMCS-mismatched so it is included in the export. When a superuser downloads the report and opens it in Excel, LibreOffice Calc, or Google Sheets with formula evaluation enabled and external-content warnings dismissed or disabled, cells beginning with =, +, -, @, tab, or CR are executed in the victim's spreadsheet context, enabling data exfiltration (e.g., HYPERLINK/WEBSERVICE) or, on Windows Excel, legacy DDE command execution. This issue is fixed in version 8.7.0.

AnalysisAI

CSV formula injection in Snipe-IT's location-scoping report export allows an authenticated low-privileged user to plant spreadsheet formulas in free-text asset fields that execute when a superuser downloads and opens the report in Excel, LibreOffice Calc, or Google Sheets. The vulnerable endpoint GET /admin/settings/location-scoping-report.csv uses a bare fputcsv() call without the League\Csv\EscapeFormula sanitization that all other CSV exports in the application apply, creating an inconsistency exploitable for data exfiltration via HYPERLINK or WEBSERVICE formulas, or command execution via legacy DDE on Windows Excel. …

Vulnerability AssessmentAI

Exploitation Three concrete conditions must align simultaneously. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 4.0 score of 5.1 (AV:N/AC:L/AT:N/PR:L/UI:P) accurately captures the two-actor nature of the attack: the injecting party needs only low-privileged authenticated access, but exploitation requires a superuser to actively download and open the CSV. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario Full exploit scenario with step-by-step reproduction available after sign-in.
Remediation Vendor-released patch: 8.7.0. … Detailed patch versions, workarounds, and compensating controls in full report.
