Questions about CVE-2014-6287
What does this mean?
The flaw lets a remote party run commands on the target system by using a %00 sequence to get past the macro filters, which allows a VBS script to be created and run.Source: github.com
Am I affected, and how do I check?
The 2.3 series of Rejetto HTTP File Server (HFS) is named as affected, and testing was done on HFS v2.3b. To check an installation, compare the HFS version number shown by the program against that series.Source: github.com
What should I do about it?
The checked facts do not name a fixed version, so no upgrade target can be given. Check the vendor's download or advisory pages for a newer release.Source: github.com
Is it being exploited?
Yes. CISA added it to its Known Exploited Vulnerabilities catalog on 2022-03-25, which means it has evidence of attacks. No public exploit code is tracked.Source: cisa.gov, cve.now feed data
What if there's no patch?
The checked facts do not describe a workaround. The flaw involves bypassing the macro filters, so the checked facts offer no filter-based mitigation.Source: github.com
