AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N
Network-reachable MITM but AC:H due to required on-path position plus revoked cert with private key; no auth required from the driver's perspective; no availability impact.

Improper OCSP response validation in the Snowflake Python, Go, JDBC, and Node.js drivers allowed a revoked TLS certificate to be accepted as valid, because OCSP responses were not reliably bound to the certificate being validated and definitive verification failures were treated as transient. A man-in-the-middle attacker holding a revoked certificate and its private key for a Snowflake or stage hostname could cause the driver to establish a TLS session to the attacker-controlled endpoint anyway, allowing the attacker to read and modify data transmitted within that connection. Successful exploitation requires that on-path position and the corresponding private key, and impact is limited to data carried within the intercepted connection. The fix is available in the patched versions listed above. Users must manually upgrade.

AnalysisAI
Improper OCSP response validation across the Snowflake Python, Go, JDBC, and Node.js drivers allowed a revoked TLS certificate to be treated as valid, enabling a man-in-the-middle attacker to intercept and tamper with driver-to-Snowflake TLS sessions. The root flaw is twofold: OCSP stapled or fetched responses were not reliably bound to the specific certificate under validation, and definitive OCSP verification failures were treated as transient errors (soft-fail), causing the driver to proceed with a connection rather than abort it. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Successful exploitation requires two simultaneous and non-trivial conditions: (1) the attacker must hold a network on-path position between the Snowflake driver host and a Snowflake service or storage-stage hostname - this could be achieved via ARP poisoning on a local network, BGP hijacking, a compromised cloud NAT or proxy, or a malicious Wi-Fi access point; and (2) the attacker must possess a TLS certificate that was previously issued for the target Snowflake or stage hostname and has since been revoked, along with the corresponding private key - this implies a prior CA compromise, certificate theft, or an attacker who originally held a legitimate cert that was later revoked. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | Real-world risk is moderate-to-high for organizations transmitting sensitive data through Snowflake drivers but is substantially constrained by the attack prerequisites. … 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 | Users must manually upgrade each affected driver; no automatic update mechanism is described. … Detailed patch versions, workarounds, and compensating controls in full report. |
