Cross-site scripting (XSS) vulnerability in CA SiteMinder 12.0 through 12.51, and SiteMinder 6 Web Agents, allows remote attackers to inject arbitrary web script or HTML via vectors involving a " (double quote) character.
The Web Agents component in CA SiteMinder R6 before SP6 CR2 and R12 before SP3 CR2 does not properly handle multi-line headers, which allows remote authenticated users to conduct impersonation attacks and gain privileges via crafted data.
CA SiteMinder allows remote attackers to bypass cross-site scripting (XSS) protections for J2EE applications via a request containing non-canonical, "overlong Unicode" in place of blacklisted characters.
