Vulnerabilities

An untrusted search path vulnerability in the AprolConfigureCCServices of B&R APROL <= R 4.2.-07P3 and <= R 4.4-00P3 may allow an authenticated local attacker to execute arbitrary code with elevated privileges.

Diffie-Hellman groups with insufficient strength are used in the SSL/TLS stack of B&R Automation Runtime versions before 6.0.2, allowing a network attacker to decrypt the SSL/TLS communication.

Improper DLL loading algorithms in B&R Automation Studio versions >=4.0 and <4.12 may allow an authenticated local attacker to execute code in the context of the product.

B&R Automation Studio Upgrade Service and B&R Technology Guarding use insufficient cryptography for communication to the upgrade and the licensing servers. A network-based attacker could exploit the vulnerability to execute arbitrary code on the products or sniff sensitive data.

The FTP server used on the B&R Automation Runtime supports unsecure encryption mechanisms, such as SSLv3, TLSv1.0 and TLS1.1. An network-based attacker can exploit the flaws to conduct man-in-the-middle attacks or to decrypt communications between the affected product clients.

Incorrect Permission Assignment for Critical Resource vulnerability in B&R Industrial Automation Automation Studio allows Privilege Escalation.This issue affects Automation Studio: from 4.6.0 through 4.6.X, from 4.7.0 before 4.7.7 SP, from 4.8.0 before 4.8.6 SP, from 4.9.0 before 4.9.4 SP.

Improper initialization implementation in Portmapper used in B&R Industrial Automation Automation Runtime <G4.93 allows unauthenticated network-based attackers to cause permanent denial-of-service conditions.

Improper Authentication vulnerability in B&R Industrial Automation B&R VC4 (VNC-Server modules). This vulnerability may allow an unauthenticated network-based attacker to bypass the authentication mechanism of the VC4 visualization on affected devices. The impact of this vulnerability depends on the functionality provided in the visualization. This issue affects B&R VC4: from 3.* through 3.96.7, from 4.0* through 4.06.7, from 4.1* through 4.16.3, from 4.2* through 4.26.8, from 4.3* through 4.34.6, from 4.4* through 4.45.1, from 4.5* through 4.45.3, from 4.7* through 4.72.9.

A reflected cross-site scripting (XSS) vulnerability exists in System Diagnostics Manager of B&R Automation Runtime versions >=3.00 and <=C4.93 that enables a remote attacker to execute arbitrary JavaScript in the context of the users browser session.

Insufficient validation of input parameters when changing configuration on Tbase server in B&R APROL versions < R 4.2-07 could result in buffer overflow. This may lead to Denial-of-Service conditions or execution of arbitrary code.

Improper Input Validation vulnerability in the project upload mechanism in B&R Automation Studio version >=4.0 may allow an unauthenticated network attacker to execute code.

Buffer Overflow vulnerability in B&R Automation Runtime webserver allows an unauthenticated network-based attacker to stop the cyclic program on the device and cause a denial of service.

An issue was discovered in B&R Industrial Automation APROL before R4.2 V7.08. Some web scripts in the web interface allowed injection and execution of arbitrary unintended commands on the web server, a different vulnerability than CVE-2019-16364.

A memory leak in the TFTP service in B&R Automation Runtime versions <N4.26, <N4.34, <F4.45, <E4.53, <D4.63, <A4.73 and prior could allow an unauthenticated attacker with network access to cause a denial of service (DoS) condition.

A denial of service vulnerability in B&R GateManager 4260 and 9250 versions <9.0.20262 and GateManager 8250 versions <9.2.620236042 allows authenticated users to limit availability of GateManager instances.

The local file inclusion vulnerability present in B&R SiteManager versions <9.2.620236042 allows authenticated users to impact availability of SiteManager instances.

A directory traversal vulnerability in SharpZipLib used in the upgrade service in B&R Automation Studio versions 4.0.x, 4.1.x and 4.2.x allow unauthenticated users to write to certain local directories. The vulnerability is also known as zip slip.

An authentication weakness in the SNMP service in B&R Automation Runtime versions 2.96, 3.00, 3.01, 3.06 to 3.10, 4.00 to 4.63, 4.72 and above allows unauthenticated users to modify the configuration of B&R products via SNMP.
