Samsung MagicINFO flaw exploited days after PoC exploit publication

Pierluigi Paganini May 06, 2025

Threat actors started exploiting a vulnerability in Samsung MagicINFO only days after a PoC exploit was published.

Arctic Wolf researchers observed threat actors beginning to exploit a high-severity vulnerability, tracked as CVE-2024-7399 (CVSS score: 8.8), in the Samsung MagicINFO content management system (CMS) just days after proof-of-concept (PoC) exploit code was publicly released.

The vulnerability is an improper limitation of a pathname to a restricted directory vulnerability in Samsung MagicINFO 9 Server version before 21.1050, an attacker can exploit the flaw to write arbitrary file as system authority.

“As of early May 2025, Arctic Wolf has observed exploitation in the wild of CVE-2024-7399 in Samsung MagicINFO 9 Server—a content management system (CMS) used to manage and remotely control digital signage displays.” reads the report published by Arctic Wolf. “The vulnerability allows for arbitrary file writing by unauthenticated users, and may ultimately lead to remote code execution when the vulnerability is used to write specially crafted JavaServer Pages (JSP) files.”

CVE-2024-7399 is a flaw in Samsung MagicINFO 9 Server’s input validation, it allows unauthenticated attackers to upload JSP files and execute code with system-level access.

Samsung first disclosed the flaw in August 2024, and at the time, there were no signs of it being exploited. However, just days after a proof-of-concept (PoC) was published on April 30, 2025, threat actors began taking advantage of it. Given how easy it is to exploit, and the public availability of the PoC, experts believe that the attacks are likely to continue.

Samsung addressed the vulnerability with the release of MagicINFO 9 Server version 21.1050 in August 2024.

“Given the low barrier to exploitation and the availability of a public PoC, threat actors are likely to continue targeting this vulnerability.” concludes the report. “Arctic Wolf will continue to monitor for malicious post-compromise activities related to this vulnerability, and will alert Managed Detection and Response customers as required when malicious activities are observed. “
