CiscoWorks Common Services versions 3.0 and 3.1 contain a vulnerability that could allow an unauthenticated, remote attacker to conduct cross-site scripting attacks.
The vulnerability exists due to an input validation error in the CiscoWorks Server login page. An unauthenticated, remote attacker could exploit this vulnerability by convincing a user to follow a malicious URL. If a user follows the malicious URL, CiscoWorks Server may return attacker-supplied script code to the affected user within the security context of the CiscoWorks Common Services site. If the attacker-supplied script code is returned, the attacker may be able to execute arbitrary script code or HTML within a user's browser session and access sensitive information.
Cisco has confirmed this vulnerability in a security response and released updated software.
Indicators of Compromise
CiscoWorks Common Services versions 3.0 and 3.1 on Solaris and Windows platforms are vulnerable.
This vulnerability exists in the login screen of the CiscoWorks Server due to a lack of input validation. The affected parameter and script details have not been disclosed.
An unauthenticated, remote attacker could exploit this vulnerability by convincing a user to follow a malicious URL that is designed to exploit the cross-site scripting flaw. If the user follows the URL, the attacker-supplied HTML or script code will be executed in the user's browser session within the security context of the affected site. The malicious URLs provided to users may target services that run on the default port, TCP port 1741, or the secure port, TCP port 443.
To exploit this vulnerability, an attacker must convince the user to follow a malicious link. An exploit could allow the attacker to execute arbitrary HTML or script code in the context of the affected site. As a result, the attacker could access confidential browser information or take actions on the affected site as the user.
