Control For Linux Arm Sl
Monthly
Concurrent monitoring requests against CODESYS control runtimes are not synchronized, letting an authenticated remote client that already holds monitoring rights corrupt internal memory structures and produce incorrect data processing or a denial-of-service condition. Affected components span the CODESYS soft-PLC family - Control RTE (SL) and Control RTE (for Beckhoff CX) SL, Control Win (SL), Runtime Toolkit, Safety SIL2, HMI (SL), Development System 3, and the Control for Linux, Linux ARM, Raspberry Pi, BeagleBone, PFC100, PFC200, PLCnext, IOT2000, emPC-A/iMX6, WAGO Touch Panels 600 and Virtual Control SL variants. Network reachable with only low privileges (PR:L), no user interaction and no non-default configuration, the race yields high integrity and availability impact but no confidentiality exposure (CVSS 4.0 base 7.2; CVSS 3.1 AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:H); no publicly available exploit code and no confirmed active exploitation were identified at time of analysis, and a vendor patch is available.
An unauthenticated remote attacker may cause the visualisation server of the CODESYS Control runtime system to access a resource with a pointer of wrong type, potentially leading to a denial-of-service (DoS) condition.
A low-privileged remote attacker could exploit the vulnerability and inject additional system commands via file system libraries which could give the attacker full control of the device. Rated high severity (CVSS 8.8), this vulnerability is remotely exploitable, low attack complexity. No vendor patch available.
CODESYS Control Runtime system before 3.5.17.0 has improper input validation. Rated high severity (CVSS 7.3), this vulnerability is remotely exploitable, no authentication required, low attack complexity. No vendor patch available.
