Medium Nessus Plugin ID 84085
SynopsisThe remote Microsoft Exchange server is affected by multiple vulnerabilities.
DescriptionThe remote Microsoft Exchange server is missing a security update. It is, therefore, affected by multiple vulnerabilities :
- A server-side request forgery vulnerability exists in Microsoft Exchange web applications due to improper management of same-origin policy. An attacker can exploit this by using a specially crafted web application, allowing further attacks to be carried out. (CVE-2015-1764)
- A cross-site request forgery vulnerability exists in Microsoft Exchange web applications due to improper management of user sessions. A remote attacker can exploit this by tricking a user into visiting a specially crafted web page, resulting in gaining access to sensitive information, impersonating the user's identity, or injecting malicious content into the victim's web browser. (CVE-2015-1771)
- An HTML injection vulnerability exists in Microsoft Exchange web applications due to not properly sanitizing user-supplied HTML strings. A remote attacker can exploit this by submitting a crafted script to a target site that uses HTML sanitization, resulting in the execution of malicious code in the security context of the user visiting the site. (CVE-2015-2359)
