CVE-2009-3030

Vulnerability

A cross-site scripting (XSS) vulnerability exists in Symantec SecurityExpressions Audit and Compliance Server versions 4.1.1, 4.1, and earlier [1]. The issue is an HTML injection flaw that allows arbitrary web script or HTML to be injected via vectors that trigger an error message in a response [1]. The exact input vector is not fully disclosed, but it occurs when the application reflects user-controllable data in error responses without proper sanitization.

Exploitation

An attacker can exploit this vulnerability by crafting a malicious request that includes injected script or HTML in a parameter that is later reflected in an error message returned by the server [1]. The attacker does not need authentication if the vulnerable endpoint is accessible pre-authentication; however, some error pages may only be reachable after login. The user must interact by viewing the error response in a browser, making this a user-assisted attack.

Impact

Successful exploitation allows the attacker to execute arbitrary web script or HTML in the context of the victim's browser session [1]. This can lead to session hijacking, credential theft, or defacement. The scope is limited to the browser's security context; no direct server-side compromise is described.

Mitigation

Symantec has not released a patch for this issue in the available references [1]. Users are advised to apply proper input validation and output encoding. As of the publication date (2009-10-15), no fixed version is documented. This CVE is not listed on CISA's Known Exploited Vulnerabilities catalog.
