Nombre: Insufficient Visual Distinction of Homoglyphs Presented to User

The product displays information or identifiers to a user, but the display mechanism does not make it easy for the user to distinguish between visually similar or identical glyphs (homoglyphs), which may cause the user to misinterpret a glyph and perform an unintended, insecure action.

Informaciones generales

Modos de introducción

Architecture and Design : This weakness may occur when characters from various character sets are allowed to be interchanged within a URL, username, email address, etc. without any notification to the user or underlying system being used.

Note: An attacker may ultimately redirect a user to a malicious website, by deceiving the user into believing the URL they are accessing is a trusted domain. However, the attack can also be used to forge log entries by using homoglyphs in usernames. Homoglyph manipulations are often the first step towards executing advanced attacks such as stealing a user's credentials, Cross-Site Scripting (XSS), or log forgery. If an attacker redirects a user to a malicious site, the attacker can mimic a trusted domain to steal account credentials and perform actions on behalf of the user, without the user's knowledge. Similarly, an attacker could create a username for a website that contains homoglyph characters, making it difficult for an admin to review logs and determine which users performed which actions.

Manual Dynamic Analysis

If utilizing user accounts, attempt to submit a username that contains homoglyphs. Similarly, check to see if links containing homoglyphs can be sent via email, web browsers, or other mechanisms.
Efectividad : Moderate

Notas de mapeo de vulnerabilidades

Justificación : This CWE entry is at the Base level of abstraction, which is a preferred level of abstraction for mapping to the root causes of vulnerabilities.
Comentario : Carefully read both the name and description to ensure that this mapping is an appropriate fit. Do not try to 'force' a mapping to a lower-level Base/Variant simply to comply with this preferred level of abstraction.

Patrones de ataque relacionados

CAPEC-ID Nombre del patrón de ataque
CAPEC-632 Homograph Attack via Homoglyphs
An adversary registers a domain name containing a homoglyph, leading the registered domain to appear the same as a trusted domain. A homograph attack leverages the fact that different characters among various character sets look the same to the user. Homograph attacks must generally be combined with other attacks, such as phishing attacks, in order to direct Internet traffic to the adversary-controlled destinations.
