New! Vulnerability Priority Rating (VPR)
Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.
VPR Score: 5.9
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)
SolutionMicrosoft has released a set of patches for Exchange 2013.
