IBM Sterling File Gateway 6.2.0.0 through 6.2.0.6_1, 6.2.1.0 - 6.2.1.2, 6.2.2.0 - 6.2.2.1 could allow a remote attacker to obtain sensitive information due to improper access control.

AnalysisAI

Improper access control in IBM Sterling File Gateway (6.2.0.0 through 6.2.0.6_1, 6.2.1.0-6.2.1.2, and 6.2.2.0-6.2.2.1) lets a remote, unauthenticated attacker reach file-transfer data they should not be able to see. The CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N, C:H) describes a trivially reachable, no-credentials-required read of sensitive information with no integrity or availability impact. …

Vulnerability AssessmentAI

Exploitation The prerequisite is that the vulnerable access-control path is reachable from the attacker's position - in practice, a Sterling File Gateway deployment whose web/partner interface is exposed beyond a trusted network, which is the normal configuration for MFT hubs accepting external trading partners. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The signals point to a genuine but situational priority. … 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 IBM has released a vendor fix; apply the corrected Sterling File Gateway fix pack identified in the IBM support page https://www.ibm.com/support/pages/node/7287180 for your 6.2.0.x, 6.2.1.x, or 6.2.2.x line, and treat any 6.2.0.6_1, 6.2.1.2, or 6.2.2.1 build as vulnerable until upgraded. … Detailed patch versions, workarounds, and compensating controls in full report.
