Vulnerabilidades

A flaw was found in Undertow. For an AJP 400 response, EAP 7 is improperly sending two response packets, and those packets have the reuse flag set even though JBoss EAP closes the connection. A failure occurs when the connection is reused after a 400 by CPING since it reads in the second SEND_HEADERS response packet…

A flaw was found in Undertow. A potential security issue in flow control handling by the browser over HTTP/2 may cause overhead or a denial of service in the server. This flaw exists because of an incomplete fix for CVE-2021-3629.

It was found that the smallrye health metrics UI component did not properly sanitize some user inputs. An attacker could use this flaw to conduct cross-site scripting attacks.

A arbitrary code execution flaw was found in the Fabric 8 Kubernetes client affecting versions 5.0.0-beta-1 and above. Due to an improperly configured YAML parsing, this will allow a local and privileged attacker to supply malicious YAML.

A flaw was found in Undertow. A buffer leak on the incoming WebSocket PONG message may lead to memory exhaustion. This flaw allows an attacker to cause a denial of service. The highest threat from this vulnerability is availability.

In CmpChannelServer of CODESYS V3 in multiple versions an uncontrolled ressource consumption allows an unauthorized attacker to block new communication channel connections. Existing connections are not affected.

In CmpBlkDrvTcp of CODESYS V3 in multiple versions an uncontrolled ressource consumption allows an unauthorized attacker to block new TCP connections. Existing connections are not affected.

In multiple CODESYS products, file download and upload function allows access to internal files in the working directory e.g. firmware files of the PLC. All requests are processed on the controller only if no level 1 password is configured on the controller or if remote attacker has previously successfully…

Multiple CODESYS Products are prone to a out-of bounds read or write access. A low privileged remote attacker may craft a request with invalid offset, which can cause an out-of-bounds read or write access, resulting in denial-of-service condition or local memory overwrite, which can lead to a change of local files.…

Multiple CODESYS Products are prone to a buffer over read. A low privileged remote attacker may craft a request with an invalid offset, which can cause an internal buffer over-read, resulting in a denial-of-service condition. User interaction is not required.

Multiple CODESYS products are affected to a buffer overflow.A low privileged remote attacker may craft a request, which can cause a buffer copy without checking the size of the service, resulting in a denial-of-service condition. User Interaction is not required.

In multiple CODESYS products, a low privileged remote attacker may craft a request, which cause an out-of-bounds read, resulting in a denial-of-service condition. User Interaction is not required.

In multiple CODESYS products, a remote attacker may craft a request which may cause an unexpected sign extension, resulting in a denial-of-service condition or memory overwrite.

In multiple CODESYS products, a low privileged remote attacker may craft a request, which may cause a heap-based buffer overflow, resulting in a denial-of-service condition or memory overwrite. User interaction is not required.

In multiple CODESYS products, a low privileged remote attacker may craft a request that cause a read access to an uninitialized pointer, resulting in a denial-of-service. User interaction is not required.

In CODESYS V2 PLCWinNT and Runtime Toolkit 32 in versions prior to V2.4.7.57 password protection is not enabled by default and there is no information or prompt to enable password protection at login in case no password is set at the controller.

In the CODESYS Development System multiple components in multiple versions transmit the passwords for the communication between clients and servers unprotected.

Multiple products of CODESYS implement a improper error handling. A low privilege remote attacker may craft a request, which is not properly processed by the error handling. In consequence, the file referenced by the request could be deleted. User interaction is not required.

A flaw was found in undertow. The HTTP2SourceChannel fails to write the final frame under some circumstances, resulting in a denial of service. The highest threat from this vulnerability is availability. This flaw affects Undertow versions prior to 2.0.35.SP1, prior to 2.2.6.SP1, prior to 2.2.7.SP1, prior to…

A vulnerability has been identified in SIMATIC PCS 7 V8.2 (All versions), SIMATIC PCS 7 V9.0 (All versions < V9.0 SP3 UC06), SIMATIC PCS 7 V9.1 (All versions < V9.1 SP1 UC01), SIMATIC WinCC Runtime Professional V16 and earlier (All versions), SIMATIC WinCC Runtime Professional V17 (All versions < V17 Upd4), SIMATIC…

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.

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.

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.

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 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.
