CWE-1094: Excessive Index Range Scan for a Data Resource

Source-backed guidance

Additional facts reviewed against primary or authoritative security sources.

Detect imprecise mappings involving CWE-1094

Review mappings to CWE-1094, Excessive Index Range Scan for a Data Resource, with MITRE's mapping and navigation criteria. Flag any selection that points to a View or Category, remains at a higher abstraction than the available evidence supports, or ignores relevant parent, child, peer, and alternative entries. Treat those findings as mapping-quality defects, correct them before publication, and retain the comparison trail for repeatable audits.

Prevent CWE-1094 through an SSDF control plan

Use NIST SSDF practices to make prevention of CWE-1094, Excessive Index Range Scan for a Data Resource, an explicit development outcome. Translate the CWE definition into security requirements and design constraints, choose safer implementation patterns and toolchain checks, and define acceptance evidence before release. Feed every confirmed occurrence back into the requirements, design review, and coding rules so the same root cause is removed across the product rather than patched in one location.

Triage CWE-1094 against known exploitation evidence

Use CISA's Known Exploited Vulnerabilities catalog to test whether a vulnerability mapped to CWE-1094, Excessive Index Range Scan for a Data Resource, has evidence of exploitation in the wild. Confirm the CVE-to-CWE root-cause mapping independently before attaching the example, then capture the affected product, required action, and remediation deadline. A missing KEV match is not evidence that the weakness is unexploited, and a KEV entry must not be generalized to every occurrence of this CWE.

Validate CWE-1094 with root-cause mapping checks

Apply MITRE's root-cause mapping quick tips to CWE-1094, Excessive Index Range Scan for a Data Resource. Confirm the finding describes the causal weakness rather than an impact or attack pattern, compare the abstraction and mapping notes with plausible alternatives, and have a second reviewer challenge the selection. Preserve the evidence and reasoning so recurring defects can be measured against one consistent identifier.

Frequently Asked Questions

What is CWE-1094: Excessive Index Range Scan for a Data Resource?+

CWE-1094: Excessive Index Range Scan for a Data Resource is a Common Weakness Enumeration (CWE) entry maintained by MITRE. The product contains an index range scan for a large data table, but the scan can cover a large number of rows. While the interpretation of "large data table" and "excessive index range" may vary for each product or developer, CISQ recommends a threshold of 1000000 table rows and a threshold of 10 for the index range.

What are the security consequences of Excessive Index Range Scan for a Data Resource?+

If exploited, CWE-1094 (Excessive Index Range Scan for a Data Resource) it can compromise Other, leading to outcomes such as Reduce Performance.

Which programming languages are affected by Excessive Index Range Scan for a Data Resource?+

CWE-1094 commonly affects Not Language-Specific. Note that weaknesses are often language-agnostic patterns, so secure coding practices apply broadly.

What is the difference between a CWE and a CVE?+

A CWE (Common Weakness Enumeration) like CWE-1094 describes a category of software weakness — the underlying flaw type. A CVE (Common Vulnerabilities and Exposures) identifies a specific, real-world vulnerability in a particular product. In short, a CWE is the kind of mistake, and a CVE is an instance of that mistake being found in software.
