CVE-2007-1420

NVD-CWE-OtherPublished: March 12, 2007· Updated: Jun 16, 2026

2.1

CVSS v3.1

Official Description

MySQL 5.x before 5.0.36 allows local users to cause a denial of service (database crash) by performing information_schema table subselects and using ORDER BY to sort a single-row result, which prevents certain structure elements from being initialized and triggers a NULL dereference in the filesort function.

Technical Analysis

CVE-2007-1420 requires local access, meaning attackers must already have a foothold on the target system.

Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.

A proof-of-concept (PoC) exploit exists for CVE-2007-1420. While not yet confirmed in active campaigns, the availability of PoC code increases exploitation risk substantially.
