An OpenSSL TLS server may crash if sent a maliciously crafted renegotiation ClientHello message from a client. If a TLSv1.2 renegotiation ClientHello omits the signature_algorithms extension (where it was present in the initial ClientHello), but includes a signature_algorithms_cert extension then a NULL pointer dereference will result, leading to a crash and a denial of service attack. A server is only vulnerable if it has TLSv1.2 and renegotiation enabled (which is the default configuration). OpenSSL TLS clients are not impacted by this issue. All OpenSSL 1.1.1 versions are affected by this issue. Users of these versions should upgrade to OpenSSL 1.1.1k. OpenSSL 1.0.2 is not impacted by this issue. Fixed in OpenSSL 1.1.1k (Affected 1.1.1-1.1.1j).

An unauthenticated remote attacker can causes the CODESYS web server to access invalid memory which results in a DoS.

Improper Neutralization of Input During Web Page Generation (XSS or 'Cross-site Scripting') vulnerability in Mediavine Mediavine Control Panel allows Stored XSS.This issue affects Mediavine Control Panel: from n/a through 2.10.4.

An unauthenticated remote attacker can use a malicious OPC UA client to send a crafted request to affected CODESYS products which can cause a DoS due to incorrect calculation of buffer size.

Control Web Panel mysql_manager Command Injection Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Control Web Panel. Authentication is required to exploit this vulnerability. The specific flaw exists within the mysql_manager module. The issue results from the lack of proper validation of a user-supplied string before using it to execute a system call. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-21080.

Control Web Panel wloggui Command Injection Local Privilege Escalation Vulnerability. This vulnerability allows local attackers to escalate privileges on affected installations of Control Web Panel. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the cwpsrv process, which listens on the loopback interface. The issue results from the lack of proper validation of a user-supplied string before using it to execute a system call. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of root. Was ZDI-CAN-21079.

Control Web Panel Missing Authentication Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Control Web Panel. Authentication is not required to exploit this vulnerability. The specific flaw exists within the implementation of authentication within the web interface. The issue results from the lack of authentication prior to allowing access to functionality. An attacker can leverage this vulnerability to execute code in the context of a valid CWP user. Was ZDI-CAN-20582.

Control Web Panel dns_zone_editor Command Injection Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Control Web Panel. Authentication is required to exploit this vulnerability. The specific flaw exists within the dns_zone_editor module. The issue results from the lack of proper validation of a user-supplied string before using it to execute a system call. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-20581.

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.
