Cross-Site Request Forgery (CSRF) Vulnerability in NPAPI Plugins

CVE-2018-12364 · MEDIUM Severity

AV:N/AC:M/AU:N/C:P/I:P/A:P

NPAPI plugins, such as Adobe Flash, can send non-simple cross-origin requests, bypassing CORS by making a same-origin POST that does a 307 redirect to the target site. This allows for a malicious site to engage in cross-site request forgery (CSRF) attacks. This vulnerability affects Thunderbird < 60, Thunderbird < 52.9, Firefox ESR < 60.1, Firefox ESR < 52.9, and Firefox < 61.
