CWE-502Published: October 4, 2023· Updated: Jun 17, 2026
Official Description
A CWE-502: Deserialization of untrusted data vulnerability exists that could allow an attacker to
execute arbitrary code on the targeted system by sending a specifically crafted packet to the
application.
Risk Analysis
Several Schneider Electric EcoStruxure products are vulnerable to deserialization of untrusted data, which can lead to remote code execution. This critical vulnerability allows an attacker to execute arbitrary code via crafted packets.
No public exploit is known, and it is not in the KEV catalog. The vulnerability is remotely exploitable with low attack complexity.
Apply the security patches provided by Schneider Electric for the affected EcoStruxure software versions.
Technical Analysis
CVE-2023-5391 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.
A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.8.
From a weakness classification perspective (CWE-502): Insecure deserialization vulnerabilities allow attackers to inject malicious objects during deserialization, potentially enabling remote code execution.
