This vulnerability allows remote attackers to create a denial-of-service condition on affected installations of C-MORE HMI EA9 Firmware version 6.52 touch screen panels. Authentication is not required to exploit this vulnerability. The specific flaw exists within the EA-HTTP.exe process. The issue results from the lack of proper input validation prior to further processing user requests. An attacker can leverage this vulnerability to create a denial-of-service condition on the system. Was ZDI-CAN-10527.

free5GC hasProtocol Compliance Violation in UPF Leading to SMF Service Disruption

free5GC is an open-source project for 5th generation (5G) mobile core networks. free5GC go-upf versions up to and including 1.2.6, corresponding to free5gc smf up to and including 1.4.0, have an Improper Input Validation and Protocol Compliance vulnerability leading to Denial of Service. Remote attackers can disrupt core network functionality by sending a malformed PFCP Association Setup Request. The UPF incorrectly accepts it, entering an inconsistent state that causes subsequent legitimate requests to trigger SMF reconnection loops and service degradation. All deployments of free5GC using the UPF and SMF components may be affected. As of time of publication, a fix is in development but not yet available. No direct workaround is available at the application level. Applying the official patch, once released, is recommended.

Pre-Authentication Denial of Service Vulnerability in MongoDB Server's OIDC Authentication

The MongoDB Server is susceptible to a denial of service vulnerability due to improper handling of specific date values in JSON input when using OIDC authentication. This can be reproduced using the mongo shell to send a malicious JSON payload leading to an invariant failure and server crash. This issue affects MongoDB Server v7.0 versions prior to 7.0.17 and MongoDB Server v8.0 versions prior to 8.0.5. The same issue affects MongoDB Server v6.0 versions prior to 6.0.21, but an attacker can only induce denial of service after authenticating.

Russh: SSH message fields were decoded through allocation-first parsers before field-specific bounds

Russh is a Rust SSH client & server library. From version 0.34.0 to before version 0.61.0, several russh client and server message handlers decoded attacker-controlled SSH strings, name-lists, and byte fields into owned allocations before applying field-specific bounds. A remote SSH peer could send oversized, high-fanout, or malformed length-prefixed fields and make the library allocate, attempt to allocate, or split data before rejecting input that should have been rejected earlier. This issue has been patched in version 0.61.0.
