CODESYS Control RTE (SL): Exposure of Resource to Wrong Sphere
CVE-2022-22515 is a high-severity exposure of resource to wrong sphere vulnerability in CODESYS Control RTE (SL) from Codesys, with a CVSS 3.1 base score of 8.1 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 V3.5.17.40 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 1.29% chance of exploitation within 30 days, higher than 71% of scored CVEs.
High severity with no evidence of exploitation so far.
