CVE-2011-0893

Vulnerability

HP Operations for UNIX version 9.10 contains a cross-site scripting (XSS) vulnerability. The issue arises from insufficient sanitization of user-supplied input in an unspecified component, allowing an attacker to inject arbitrary web script or HTML. The vulnerability is remotely exploitable and does not require authentication, as indicated by the CVSS vector (AV:N/AC:M/Au:N/C:N/I:P/A:N) [1].

Exploitation

An attacker can exploit this vulnerability by crafting a malicious request containing script code and tricking a user into interacting with a crafted link or page served by the affected HP Operations interface. No prior authentication is needed, but the attack requires some user interaction (e.g., clicking a link) to trigger the XSS payload [1].

Impact

Successful exploitation allows the attacker to execute arbitrary JavaScript in the context of the victim's browser session. This can lead to disclosure of sensitive information, session hijacking, or unauthorized actions performed on behalf of the authenticated user. The CVSS impact score indicates partial integrity compromise with no direct confidentiality or availability impact [1].

Mitigation

HP has released a hotfix to address this vulnerability. Affected users should contact HP Services support and request the hotfix package QCCR1A121284_QCCR1A121281_hotfix.tar.gz [1]. No workarounds are documented in the available reference.
