Security Vulnerabilities
- CVEs Published In April 2022
An authenticated remote attacker can cause a null pointer dereference in the CmpSettings component of the affected CODESYS products which leads to a crash.
An authenticated, remote attacker can gain access to a dereferenced pointer contained in a request. The accesses can subsequently lead to local overwriting of memory in the CmpTraceMgr, whereby the attacker can neither gain the values read internally nor control the values to be written. If invalid memory is accessed, this results in a crash.
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 products.
The SysDrv3S driver in the CODESYS Control runtime system on Microsoft Windows allows any system user to read and write within restricted memory space.
An unauthenticated, remote attacker can disrupt existing communication channels between CODESYS products by guessing a valid channel ID and injecting packets. This results in the communication channel to be closed.
A bug in CmpUserMgr component can lead to only partially applied security policies. This can result in enabled, anonymous access to components part of the applied security policy.
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.
ASUS RT-AX56U’s update_json function has a path traversal vulnerability due to insufficient filtering for special characters in the URL parameter. An unauthenticated LAN attacker can overwrite a system file by uploading another file with the same file name, which results in service disruption.
ASUS RT-AX56U’s update_PLC/PORT file has a path traversal vulnerability due to insufficient filtering for special characters in the URL parameter. An unauthenticated LAN attacker can overwrite a system file by uploading another PLC/PORT file with the same file name, which results in service disruption.
ASUS RT-AX56U’s SQL handling function has an SQL injection vulnerability due to insufficient user input validation. An unauthenticated LAN attacker to inject arbitrary SQL code to read, modify and delete database.
