Vulnerabilities

A Vulnerability is a state in a computing system (or set of systems) which either (a) allows an attacker to execute commands as another user, (b) allows an attacker to access data that is contrary to the specified access restrictions for that data, (c) allows an attacker to pose as another entity, or (d) allows an attacker to conduct a denial of service.Advisories relating to Symantec products may be viewed here.

Microsoft Office CVE-2017-11876 Cross Site Request Forgery Vulnerability

Risk:
High
Date Discovered:
November 14, 2017
Description:
Microsoft Office is prone to a cross-site request-forgery vulnerability. Exploiting this issue may allow a remote attacker to perform certain unauthorized actions in the context of the affected application. Other attacks are also possible.
Technologies Affected
  • Microsoft Project Server 2013 Service Pack 1
  • Microsoft SharePoint Enterprise Server 2016
Recommendations
  • Run all software as a nonprivileged user with minimal access rights.
    To reduce the impact of latent vulnerabilities, always run nonadministrative software as an unprivileged user with minimal access rights.
  • Deploy network intrusion detection systems to monitor network traffic for malicious activity.
    Deploy NIDS to monitor network traffic for signs of suspicious or anomalous activity. This may help detect malicious actions that an attacker may take after successfully exploiting vulnerabilities in applications. Review all applicable logs regularly.
  • Do not accept or execute files from untrusted or unknown sources.
    To reduce the likelihood of successful exploits, never handle files that originate from unfamiliar or untrusted sources.
  • Implement multiple redundant layers of security.
    Since this issue may be leveraged to execute code, we recommend memory-protection schemes, such as nonexecutable stack/heap configurations and randomly mapped memory segments. This tactic may complicate exploits of memory-corruption vulnerabilities.
Updates are available. Please see the references or vendor advisory for more information.
