Kerentanan Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') pada concretecms concrete cms. Skor CVSS 3.1 4.8 (Medium) menurut NVD.

Deskripsi (NVD)

Concrete CMS 9.5.0 and below is vulnerable to Stored XSS via OAuth integration name. The OAuth authorize template renders the integration name (admin-controlled) through Concrete's t() translation helper as a sprintf-style format. The <strong>...</strong> wrap is built by PHP string interpolation before t() runs, so the integration name lands in the translated output as raw HTML. A rogue admin could potentially snoop on login submissions.The Concrete CMS security team gave this vulnerability a CVSS v.4.0 score of 7.3 with vector CVSS:4.0/AV:N/AC:L/AT:P/PR:H/UI:P/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N  Thanks Yonatan Drori (Tenzai) for reporting.
