Technical details
A cross-site scripting (XSS) vulnerability exists in Microsoft Office SharePoint due to improper neutralization of input during web page generation (CWE-79). An attacker with low-privileged credentials (PR:L) can exploit this over the network by injecting malicious scripts into SharePoint pages. Successful exploitation requires a victim to interact with the affected page (UI:R). This allows the attacker to perform spoofing attacks, potentially leading to unauthorized data disclosure or integrity compromises within the context of the victim's session. Microsoft has released security updates to address this issue.
