A vulnerability in Cisco Wide Area Application Services (WAAS) software, when configured with the SharePoint acceleration feature, could allow an unauthenticated, remote attacker to cause a reload of the application optimization handler. The vulnerability is due to incorrect parsing of SharePoint responses. An attacker could exploit this vulnerability by convincing a user to access a malicious SharePoint application. An exploit could allow the attacker to cause partial service disruptions during the reload of the application optimization handler. Cisco has confirmed the vulnerability in a security notice and released software updates. To exploit the vulnerability, the attacker may provide a link that directs a user to a site that contains a malicious SharePoint application and use misleading language or instructions to persuade the user to follow the provided link.
The Cisco Product Security Incident Response Team (PSIRT) is not aware of any public announcements or malicious use of the vulnerability that is described in this advisory.
