CVE-2024-57653

What it actually does

Crafted SQL statements cause a denial of service condition within the qst_vec_set_copy component.

Why it matters to the business

Service availability is disrupted, leading to operational downtime and potential loss of access to dependent systems.

How an attack unfolds

An attacker connects to the database and submits specially crafted SQL statements targeting the vulnerable vector handling logic, resulting in a crash or hang of the service.

How to fix it

Upgrade flashplugin-nonfree on Ubuntu 14.04 LTS to version 11.2.202.632ubuntu0.14.04.1 or later. Apply vendor patches for virtuoso-opensource if a matching fixed release becomes available.

How to confirm the fix worked

Confirm the installed package version matches or exceeds the listed fixed version and test that crafted SQL no longer produces a denial of service response.

Typical attack path

1. Locate an exposed instance of the affected database software
2. Establish a client connection with valid credentials
3. Submit crafted SQL statements via the qst_vec_set_copy path
4. Trigger repeated requests to sustain the denial of service condition

How to detect it

Inspect database logs and process monitors for repeated crashes or hangs immediately following SQL statement execution; correlate with connection records showing unusual query patterns.

What your security team should do

• Prioritize patching within standard change windows given low EPSS and absence from KEV
• Review database access controls to limit exposure of the affected component
• Monitor for unusual SQL patterns that could indicate attempted exploitation
