RSA Authentication Agent postdata parameter cross-site scripting
| rsa-auth-postdata-xss (20098) |  Medium Risk |
Description:
RSA Authentication Agent for Web is vulnerable to cross-site scripting caused by improper validation of user-supplied input to the postdata parameter. A remote attacker could embed malicious script in the postdata parameter in a URL request to the /WebID/IISWebAgentIF.dll which, once the link is clicked, would be executed in the victim's Web browser within the security context of the hosting site. An attacker could use this vulnerability to steal the victim's cookie-based authentication credentials.
Platforms Affected:
- Microsoft, IIS 5.0
- Microsoft, IIS 6.0
- Microsoft, Windows 2000 SP4
- Microsoft, Windows 2003 Server Enterprise
- Microsoft, Windows 2003 Server Standard
- Microsoft, Windows 2003 Server
- RSA, Authentication Agent for Web 5.2
