CVE-2024-39717
CVE-2024-39717 is a security flaw in Versa Director. Attackers can upload a file to Versa Director and make it run. The US Cybersecurity and Infrastructure Security Agency (CISA) added it to its catalog of flaws known to be used in attacks on 23 Aug 2024.[1]
Versa Director is business software or equipment. Most families won’t have it, but attackers break into it to get inside companies, and from there to what those companies hold about their customers, patients and staff. Fixed in version 21.2.3 before 2024-06-21, 21.2.3_2024-06-21, 22.1.2_2024-06-21 and 22.1.3_2024-06-21.
Description
CISA calls it a dangerous file type upload in Versa Director. In its words: “The Versa Director GUI contains an unrestricted upload of file with dangerous type vulnerability that allows administrators with Provider-Data-Center-Admin or Provider-Data-Center-System-Admin privileges to customize the user interface. The “Change Favicon” (Favorite Icon) enables the upload of a .png file, which can be exploited to upload a malicious file with a .png extension disguised as an image.”[1]
The CVE record adds: “The Versa Director GUI provides an option to customize the look and feel of the user interface. This option is only available for a user logged with Provider-Data-Center-Admin or Provider-Data-Center-System-Admin. (Tenant level users do not have this privilege). The “Change Favicon” (Favorite Icon) option can be mis-used to upload a malicious file ending with .png extension to masquerade as image file. This is possible only after a user with Provider-Data-Center-Admin or Provider-Data-Center-System-Admin has successfully authenticated and logged in.”[2]
The underlying weakness is unrestricted file upload (CWE-434), in MITRE’s list of common software weaknesses.
It scores 7.2 out of 10 on the Common Vulnerability Scoring System, which rates it high, scored by NVD using CVSS 3.1.[2]

Exploitation
CISA added it to its catalog of known exploited vulnerabilities on 23 Aug 2024, within a day of it being made public. CISA lists a flaw only when it has reliable evidence of it being exploited, and gave US federal agencies until 13 Sep 2024 to fix it.[1]
FIRST’s Exploit Prediction Scoring System, which estimates how likely a flaw is to be used in attacks in the next 30 days from what it sees across the internet, puts it at 4%. That’s in the top 10% of the flaws it scores.[4]
CISA assesses it as not automatable: each attack takes some work.
CISA doesn’t say who was attacked, or how.
Fix
Versa has published a fix or advice.[3] CISA’s required action: “Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable.”[1]
- Check whether you use it.Versa Director is business software or equipment, so most families won’t have it. If you run a business, or work from home on company equipment, ask whoever looks after your IT.
- Send this page to your IT person.Ask them to confirm it’s fixed (fixed in version 21.2.3 before 2024-06-21, 21.2.3_2024-06-21, 22.1.2_2024-06-21 and 22.1.3_2024-06-21), or not in use. CISA gave US government agencies until 13 Sep 2024 to fix it.
- If it can’t be fixed, take it offline.CISA’s advice when there’s no fix is to stop using the product, or take it off the internet, until there is one.
You can’t fix someone else’s server, but you can watch for what follows a break-in like this: a breach notice, a password reset you didn’t ask for, or a scam message that knows things it shouldn’t. HARD watches for those for you and your family.
