Since this thread auto closes today I’d like to sum up the current status from my point of view for any latecomers: Right out of the box, the [TRB500 is vulnerable](https://teltonika-networks.com/support/security-centre#:~:text=Three%20denial%2Dof%2Dservice%20vulnerabilities%20in%20third%2Dparty%20chipsets%20affecting%20our%205G%20devices) to three high severity (CVSS score: 7.5) issues: - [CVE-2023-33042](https://nvd.nist.gov/vuln/detail/CVE-2023-33042) - [CVE-2023-33043](https://nvd.nist.gov/vuln/detail/CVE-2023-33043) - [CVE-2023-33044](https://nvd.nist.gov/vuln/detail/CVE-2023-33044) The built-in FOTA modem updater is disabled and there are no other modem firmware versions available online other than these two: - RG501QEUAAR12A08M4G\_04.001.04.001 **(vulnerable)** - RG501QEUAAR12A07M4G\_04.001.04.001 **(vulnerable)** According to Teltonika’s own security center, and based on the common hardware config among devices, the latest known non-vulnerable modem version is: - RG501QEUAAR12A11M4G\_04.200.04.200 **(safe)** The only way to get this updated firmware though is through private channels, e.g. by contacting Teltonika through this forum (you need to to this in a separate thread since this one closes today). I haven’t seen any official update yet but it is safe to say that they are aware of the problem and are working on it. Maybe one of their representatives can leave a comment here for us to feel more comfortable, an ETA would be even better. @Teltonika: Thanks for the support so far, if you are looking for beta testers I’m definitely interested in joining in (you know where to find me). --- _[View the full topic](https://community.teltonika.lt/t/trb500-latest-modem-firmware/10373)._
