Actively exploited vulnerability
SugarCRM products: code execution flaw under attack
CVE-2023-22952 · Multiple SugarCRM Products Remote Code Execution Vulnerability
What is affected
SugarCRM products are found on ordinary personal computers and phones, so this is not only a problem for companies. If you use them and have not updated since the fix was released, you are exposed.
Multiple SugarCRM products contain a remote code execution vulnerability in the EmailTemplates. Using a specially crafted request, custom PHP code can be injected through the EmailTemplates.
What an attacker can do
This is a code execution flaw. It lets an attacker run their own commands or programs on the affected system. In practice that usually means taking it over: installing malware, stealing data or using it to reach other devices on the same network.
- How it is reached
- Over the internet or network
- Access the attacker needs
- A basic user account
- Does the victim have to do something?
- No, works without the victim doing anything
What to do
- Update SugarCRM products now. Open the update or "About" screen, install whatever is offered and restart the app or device, because the fix is not active until you do.
- Turn on automatic updates so the next fix arrives without you having to look for it.
- If your device is too old to receive this update, stop using the affected app for anything sensitive and plan a replacement.
Apply updates per vendor instructions.

How urgent is it
CISA added this vulnerability to its Known Exploited Vulnerabilities catalogue on February 2, 2023, which means there is reliable evidence of attacks in the wild. US federal agencies must fix it by February 23, 2023, a deadline that has already passed. That deadline does not bind anyone else, but it shows how seriously the agency rates it.
The EPSS model estimates a 80% probability that this flaw will be exploited somewhere in the next 30 days. That is higher than 99.6% of all scored vulnerabilities.
Its CVSS severity score is 8.8 out of 10 (high), as recorded in the US National Vulnerability Database.
