DescriptionCVE.org

Dool in versions up to 1.3.8 is vulnerable to a CSV injection vulnerability when exporting data to a CSV file, as it fails to sanitize cell content beginning with special formula characters like =, +, -, or @. A local attacker can exploit this by running a process with a crafted name starting with =, which injects malicious formulas into the CSV output that execute when a victim opens the file in a spreadsheet application. The issue was addressed by pull request #117

AnalysisAI

CSV injection in Dool through version 1.3.8 allows a local attacker who can control process names on a monitored host to plant malicious spreadsheet formulas into CSV exports. When an administrator or analyst opens the exported file in a spreadsheet application such as Microsoft Excel or LibreOffice Calc, the injected formula executes in that application's context. …

Vulnerability AssessmentAI

Exploitation Two specific, sequential conditions must both be met. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 4.0 score of 4.6 with AV:L/PR:N/UI:A accurately reflects the constrained exploitation model: the attacker must have local access to the monitored system to launch a crafted process, and separately a victim must actively open the exported CSV in a spreadsheet application with formula execution enabled. … 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 The upstream fix is available via GitHub pull request #117 at https://github.com/scottchiefbaker/dool/pull/117; however, no officially tagged release version incorporating this fix has been independently confirmed, so deployers should apply the PR directly from the repository or monitor for a tagged release. … Detailed patch versions, workarounds, and compensating controls in full report.
