CVE-2023-1932
Description
A flaw was found in hibernate-validator's 'isValid' method in the org.hibernate.validator.internal.constraintvalidators.hv.SafeHtmlValidator class, which can be bypassed by omitting the tag ending in a less-than character. Browsers may render an invalid html, allowing HTML injection or Cross-Site-Scripting (XSS) attacks.
Statement
Hibernate-validator is packaged with Red Hat OpenStack Platform 13.0's OpenDaylight (ODL). However, because ODL is technical preview in this version and the flaw is moderate, Red Hat will not be releasing a fix for the OpenStack package at this time.
Supported versions of Satellite 6 embed vulnerable versions of hibernate-validator inside the candlepin component. However, the vulnerable SafeHtmlValidator functionality is not in use, so it is not possible to exploit it.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.
