CODESYS Control RTE (SL): Incorrect Resource Transfer Between Spheres
CVE-2025-41660 is a high-severity incorrect resource transfer between spheres vulnerability in CODESYS Control RTE (SL) from Codesys, with a CVSS 3.1 base score of 8.8 out of 10. It can be exploited remotely over the network by an attacker with a low-privileged account, without any action from a user. The record lists version 3.5.22.0 as the first without the flaw, so updating CODESYS Control RTE (SL) to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.46% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update CODESYS Control RTE (SL) to 3.5.22.0 or a later version.
- Update CODESYS Control RTE (for Beckhoff CX) SL to 3.5.22.0 or a later version.
- Update CODESYS Control Win (SL) to 3.5.22.0 or a later version.
