Severity

critical9.2

CVSS measures technical severity, not the likelihood of an attack.

Known exploitation

Not listed in the checked CISA KEV catalog

Absence from CISA KEV does not rule out attacks.

Public exploit

Not established by this record

Missing evidence does not mean no public exploit exists.

Remediation

Fix status not established

No structured fix or guidance is available here. Check the latest publisher advisory.

What this means

Amazon Redshift JDBC Driver versions before 2.3.0 may allow an attacker with influence over the JDBC connection URL or AWS credentials profile to execute arbitrary code, given a suitable class on the application classpath. The weakness is due to unsafe reflection in connection parameter handling. An upgrade to version 2.3.0 or later is recommended.

Summarized by @cf/meta/llama-3.3-70b-instruct-fp8-fast. Verify details against the original sources.

What to do

Compare your installed product and version with the affected versions above. A matching product name alone does not confirm exposure.

No structured fix or remediation guidance is available here. Check the full source description and vendor’s latest advisory for a patch or workaround; do not assume another version is safe.

Original source description

Read the full publisher description

Unsafe reflection in the connection parameter and credentials profile handling of Amazon Redshift JDBC Driver before 2.3.0 might allow an actor who can influence the JDBC connection URL or the AWS credentials profile to execute arbitrary code in the application context, provided a suitable class is available on the application classpath.

To remediate this issue, users should upgrade to version 2.3.0 or later.
