CWE-1254 (Incorrect Comparison Logic Granularity) documents a weakness type used across vulnerability databases and security assessments. Use the sections below for definition, context, and mapped CVEs.
Security impact
Security impact: Depends on product and context; use CVE records, severity scores, and MITRE guidance to prioritize.
Description
The product's comparison logic is performed over a series of steps rather than across the entire string in one operation. If there is a comparison logic failure on one of these steps, the operation may be vulnerable to a timing attack that can result in the interception of the process for nefarious purposes.
