CVE-2022-48197
Published: 02 January 2023
Summary
CVE-2022-48197 is a medium-severity Cross-site Scripting (CWE-79) vulnerability in Yui Project Yui. Its CVSS base score is 6.1 (Medium).
Operationally, ranked in the top 2.8% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis
Reflected cross-site scripting exists in the Sandbox examples hosted in the YUI2 repository. The vulnerability is tracked as CVE-2022-48197 with a CVSS 3.1 score of 6.1 and is classified under CWE-79. Only the Sandbox examples are affected; the YUI2 download distributions, the TreeView component, and the overall YUI JavaScript library are explicitly stated as unaffected. The issue impacts only products that are no longer supported by the maintainer.
An unauthenticated remote attacker can supply a crafted request that is reflected back to a victim who visits a malicious link or page referencing the Sandbox examples. Successful exploitation allows the attacker to execute arbitrary script in the context of the affected Sandbox page, resulting in limited confidentiality and integrity impacts without requiring privileges or user interaction beyond visiting the link.
Public references include a Packet Storm advisory and a GitHub repository containing proof-of-concept material, but no vendor patches or mitigation guidance are provided because the affected code resides in an unsupported repository. The EPSS score has remained at 0.3674 with no material increase after disclosure.
