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.
In the CODESYS Development System multiple components in multiple versions transmit the passwords for the communication between clients and servers unprotected. Rated high severity (CVSS 7.5), this vulnerability is remotely exploitable, no authentication required, low attack complexity. No vendor patch available.
A remote, unauthenticated attacker can send a specific crafted HTTP or HTTPS requests causing a buffer over-read resulting in a crash of the webserver of the CODESYS Control runtime system. Rated high severity (CVSS 7.5), this vulnerability is remotely exploitable, no authentication required, low attack complexity. No vendor patch available.
An unauthenticated, remote attacker can disrupt existing communication channels between CODESYS products by guessing a valid channel ID and injecting packets. Rated high severity (CVSS 7.5), this vulnerability is remotely exploitable, no authentication required, low attack complexity. No vendor patch available.
A remote, authenticated attacker could utilize the control program of the CODESYS Control runtime system to use the vulnerability in order to read and modify the configuration file(s) of the affected. Rated high severity (CVSS 8.1), this vulnerability is remotely exploitable, low attack complexity. No vendor patch available.
An authenticated, remote attacker can gain access to a dereferenced pointer contained in a request. Rated high severity (CVSS 7.1), this vulnerability is remotely exploitable, low attack complexity. No vendor patch available.
An authenticated remote attacker can cause a null pointer dereference in the CmpSettings component of the affected CODESYS products which leads to a crash. Rated medium severity (CVSS 6.5), this vulnerability is remotely exploitable, low attack complexity. No vendor patch available.
An issue was discovered in 3S-Smart CODESYS V3 products. Rated high severity (CVSS 8.8), this vulnerability is no authentication required, low attack complexity. No vendor patch available.
