AI Powered Q&A
Can you explain this vulnerability to me?
This vulnerability exists in IBM Verify Identity Access Container and IBM Security Verify Access products in certain versions. It occurs because certificate listings retrieved via a browser session return a JSON payload but incorrectly specify the response Content-Type as text/html.
Because the content is delivered with an HTML MIME type, browsers may interpret the JSON data as executable script under certain conditions. This misinterpretation creates an opportunity for JavaScript injection, which can lead to cross-site scripting (XSS) attacks.
How can this vulnerability impact me? :
The vulnerability can allow an attacker to perform cross-site scripting (XSS) attacks by injecting malicious JavaScript into the JSON payload that is interpreted as executable script by the browser.
This can lead to unauthorized actions being performed in the context of the affected user's browser session, potentially compromising user data confidentiality and integrity.
According to the CVSS score, the impact includes low confidentiality and integrity impact, no availability impact, and requires low privileges and user interaction.
