MISP contains a reflected cross-site scripting (XSS) vulnerability in the legacy taxonomy tag management confirmation forms (add tag and disable tag).<\/p>\n
The affected forms echoed a user-supplied tag name value from the request unescaped into the rendered HTML output. An attacker who can induce a site administrator to visit a crafted URL containing a malicious tag name parameter can execute arbitrary JavaScript in the administrator’s browser session.<\/p>\n
Preconditions:<\/p>\n
– The target must be running a MISP instance with the legacy taxonomy tag confirmation views enabled.<\/p>\n
– The victim must be an authenticated site administrator.<\/p>\n
– The victim must navigate to the attacker-crafted URL (e.g., via a phishing link).<\/p>\n
Security impact:<\/p>\n
– Execution of arbitrary client-side script in the context of the administrator’s browser.<\/p>\n
– Potential theft of session tokens, CSRF tokens, or other sensitive data accessible from the page.<\/p>\n
– Potential for performing privileged actions on behalf of the administrator within the MISP interface.<\/p>\n
