The vulnerability of the TCP/IP communication protocol implementation in the development environment for programmable logic controllers ISaGRAF Workbench allows a attacker to upload, read, and delete files.

The vulnerability of the TCP/IP communication protocol implementation in the development environment for programmable logic controllers ISaGRAF Workbench relates to the transmission of data in an unencrypted form. Exploiting this vulnerability allows a malicious actor to upload, read, and delete...

CVE-2023-34188

The HTTP server in Mongoose before 7.10 accepts requests containing negative Content-Length headers. By sending a single attack payload over TCP, an attacker can cause an infinite loop in which the server continuously reparses that payload, and does not respond to any other requests...

The vulnerability of the ISN Handler TCP connection processing component in Siemens’ software and hardware products allows attackers to intercept existing sessions.

The vulnerability of the ISN Handler TCP connection processing component in Siemens’ software and hardware products is related to the predictability of random session numbers. Exploiting this vulnerability allows a malicious actor to intercept existing sessions remotely...

kernel: NFSD: Protect against send buffer overflow in NFSv2 READ

In the Linux kernel, the following vulnerability has been resolved: NFSD: Protect against send buffer overflow in NFSv2 READ Since before the git era, NFSD has conserved the number of pages held by each nfsd thread by combining the RPC receive and send buffers into a single array of pages. This...
